Synology btrfs vs ext4 reddit. People tend to consider it more stable.

Synology btrfs vs ext4 reddit BTRFS isn't a Synology specific feature, it's a linux file system. Make a hyper backup to the new disk with all settings/programs (and export containers according to guide. I use a DS-918+ with 3 6TB drives at home and one empty slot. Looking at ordering a new DS1821+ shortly and will be coming from an older diskstation currently with two volumes which are Ext4. It has ~6-7TB of data on the 12TB (SHR) volume. Backed up data to USB drives. Why do you think ext4 would be better regarding fragmentation? Looks to me if anything btrfs has more features avoiding fragmentation like tail packing. g usb, you could format those drives in either ntfs or exfat , and they can be read by either Synology or Windows. It just find the issue and alert you, don't blame it. Assuming you want to have a volume 2 with the 2x6 drives, add those to bay 3-4. Btrfs is always faster than ext4 when used with the nodatacow mount option. Basically Btrfs but better in every way (mostly because everything works, Btrfs is still a work in progress). F2FS on the other side, even though is driven by a private company, it's open source and it's showing very good potential for desktop/phone environments. Depends. Actually, Btrfs might have the upper hand there even, if zstd filesystem compression is used. All of the drives that had data converted from ext4 to btrfs with a btrfs versions prior to that keenel v. They use md-raid instead, and run btrfs over it as on single virtual disk. Some of the things BTRFS was slow at and you had to have the speed then maybe you'd have to disable CoW or use EXT4 and live without the security of CoW and checksumming. With SSD array this is negligible, but not zero. I documented the process and wrote up a blog post for anyone that is considering the same thing. Try to copy a very big file. You CAN make a bigger storage pool. We got a new one and are wondering if EXT4 is still the best for big files and video editing or is BTRFS is the way to go. I have 32TBs (29 actual) of capacity but only about 14 of that was used so my situation was a little different than most. Similar to HW raid. The 218+ supports BTRFS but the 416 does not. Get the Reddit app Scan this QR code to download the app now A community to discuss Synology NAS and networking devices Members Online. (DS218+, 2x4GB HDD) Hey there! I'm very new to the world of NAS systems, I'm thinking of buying the DS 220j as my first NAS. 2). Only works with btrfs. Because somebody at Synology liked BTRFS, but then BTRFS stagnated in terms of it's built-in volume management, and flexible storage resizing. As of DSM 7. I’m going to upgrade from my old ds213j. The array presents itself to btrfs as a single device. Hi all I am expecting a new NAS on Saturday and planning to migrate data and configs. () Synology has implemented the layers in between the file systems and disks to ensure that Synology has full control to achieve the highest stability. Here we discuss the next These were formatted in ext4 because Btrfs is unavailable on a DS212. Btrfs or EXT4. Btrfs is better. Performance shouldn't be your concern. Imagine a 12TB volume taken down for filesystem checks. After reading the threads about ext4 vs. If you are concerned about the external drives, e. If you can setup this, the data volume should use BTRFS, the surveillance volume ext4. The redundancy is planned to be handled by Snapraid and the disks are planned to be independent. For Btrfs there are several options for deduplication. HDD is also more reliable, besides being cheaper. Stepping away from btrfs also means stepping away from several "advanced" Synology packages and features exclusive to btrfs formatted systems. We basically had to modify the SID of our AD to achieve unified ids. Synology passes btrfs checksum errors up the stack to mdraid/lvm to allow it to then repair from parity/redundancy, which is not trivial to implement. Basically I'm going to be using a Windows computer most of the May 12, 2023 · In the context of Synology NAS devices, both Btrfs and Ext4 are viable file systems, but they serve different needs. Synology backup doesn't scale if you have backups of small files with a size greater than 10TB. Synology's NAS also use it. Not trivial on a boot disk in Linux. I took the opportunity to finally move off ext4 to BTRFS. Btrfs has it's own volume management. People tend to consider it more stable. I still prefer btrfs for root because of snapshots and compression. So they don't allow you ( at least without custom non supported scripts) to make a volume of 108tb. Of course "some people" say restore doesn't work. agree with ssps, just run memory test first. So in the end, any filesystem besides Ext4 might offer some slight performance improvements over Ext4, but they are much less reliable. Overall, my experience with btrfs vs lvm are similar. Since Fedora does literally nothing to take advantage of BTRFS (unlike OpenSuSE, for example), I don't get much out of it, though - checksumming is really it. provides. I hope that Ugreen can keep their promises and at worst it will shake up the competition, although I don’t think QNAP / Synology is worried about this. E. Looked through the sub and couldn’t find the exact answer. If I should keep BTRFS on my DS920+, or you would keep BTRFS in my situation, can I have a vote up. Awhile ago I was looking for advice on how to migrate an ext4 volume to btrfs on my 920+. e. I found BTRFS to be plenty stable, and with checksumming and self healing - even more so. Yes, btrfs is a "next gen" filesystem, but it's still unstable; while ext4 is proven and solid. Makes the learning curve less painful. Btrfs is definitely a much more modern filesystem which is why many use it, but there's a reason ext4 is the default on almost every distro. Some things BTRFS was faster, some things EXT4. 2 TB of data. For more information and supported models, refer to this article. You can use the Synology product search to filter for all models that support BTRFS. So yes the size after raid matters. Additionally, some important shares get snapshot-replicated to another NAS, and one small-but-critical share gets Hyperbackup to SynoC2. For my file servers data volumes I use btrfs. Then you kina abandon ext4 metadata and start using the btrfs one. r/ipv6. I think F2FS is used sometimes. Will I see a big performance hit? I read that btrfs is no friend to database activities. Synology does not currently offer a file system conversion application that I'm aware of. 4TB, and it loaded and migrated without a hitch up to the very latest DSM. Once I installed the client app on my laptop it said that I would need to have the synology drives formatted as btrfs. However, it's backwards compatible with ext3. I understand some people swear by BTRFS, some don't, but it seems an almost religious debate, like Mercedes vs BMW. That was basically migrating shares, blowing up the array, rebuilding an array as BTRFS. And deduplication matters. It took a long time to write the data but it was pretty easy overall. RAID6 in 1819+ Hey all - currently have a DS1819+ with (8) 4TB WD Red disks in "RAID6" on EXT4 filesystem. seems to be smashup of your list. I don't have immense storage needs,… Edit: I'm thinking of using ext4 because I understand BTRFS is slower and I don't think I need the extra features like snapshot etc. And so on. Sometimes performance. A place to answer all your Synology questions. Is that sufficient? Apart from that, btrfs is the default filesystem of for example Suse Linux and Fedora. I had to manually reimport dkms and the volumes every time a new kernel was installed. So btrfs can't be that bad. Then you have the raidz1 to raidz3 variants which are similar (bot not the same) to raid 5/6. You’d be an idiot to pay the premium for a synology and not use that feature. It'd need synopartindex and maybe an older, pre kernel 4. You can kill the volume and recreate with btfrs, copy from volume 1 to new BTRFS volume 2 and carry on. Best Strategy to migrate from EXT4 to BTRFS? I have a DS-918+ with 3 6TB drives and my single EXT4 volume is ~43% full. Ext4. I'm currently using BTRFS but I really don't use snapshots or any other feature that BTRFS provides but Ext4 doesn't. there is a way to convert ext4 to btrfs by basically fencing off a bit of a free space on the ext4 filesystem, creating btrfs filesystem metadata there, and then creating the files in btrfs filesystem that "point" to the same data blocks that ext4 uses. It may still suit as part of your backup strategy if you have a reliable onsite backup or a cloud backup, or if you’re comfortable that having two 220j devices minimizes the odds of both having bitrot occur at the same time. Don't get me wrong. This list is known as the "Synology Products Compatibility List". "Due to the Btrfs RAID issues, Synology chose Linux RAID. The only thing that did recover the space was the following command entered by the Synology developers in Tiawan on my NAS in a shell. This is my interpretation of what I have to do. Linux vs. You could just use 5x disks in SHR1 so you don't have to blow the pool away everytime you want to change a disk (allows raid auto bad block repair and allows btrfs self heal if Checksum is used) but this is your choice I want to change from current ext4 to btrfs system and I was wondering if I can add one more 18TB drive and create a new storage pool with btrfs, transfer my data from current volume to the new one. 1, use the Btrfs (Peta Volume) file system instead. "Instead of buying a cheap j-model, which generally does not support BTRFS, upgrade to a model that does support BTRFS, for example a model in the plus-series. If your DSM version is 7. Only a reflink is made. So your raid 5 example is most likely valid. btrfs sub cr /mnt/@ (the @ alone is the convention for "root directory" in btrfs) btrfs sub cr /mnt/@home. Personal order of preference: ZFS, ext4, Btrfs, XFS. There is a mix of digital photos (rarely changes) TimeMachine backups (always changing), Videos (rarely changes) and work project files (small and large, some of which change often, some of which don't. Now, how good BTRFS is at restoring is directly proportional to how much the user understands how it works. I would highly recommend you stay from this in production. Happened many times. Our current Synology uses ext4 and LVM. If you're using RAID5 don't use btrfs, it's RAID5 feature still has reliability concerns. For most uses I still use ext4. And it will work straight of the bat? I then deleted the larger volume and re-created it to BTRFS. I was using LVM on LUKS with ext4 and kept getting file corruptions without doing anything special and being forced to repair filesystem every once in a while to boot into the OS. 1. Ext 4 has been around a good while longer than Btrfs. I would deploy ext4 on smallest appliances only, and Btrfs on servers and workstations. As you said, DSM is much easier to use and provides more features/configurations than QNAP. This means that it will eventually show up all over the place, but Synology was the first to get it implemented stably between Synology and I guess the best way to move forward is to buy 4 new HDDs put the old DS412+ in it's original configuration 4 HDDs X 4TB each with EXT4 and do some sort of data transfer to the new DS920+ using the btrfs format for the new HDD that I buy, correct? Ext4 is preferred for storage pools used by Surveillance Station. The question is XFS vs EXT4. The rest of the btrfs filesystem is generally OK, if confusing. There's no way to convert in-place to ext4. In support of this, I was hoping to create new btrfs volumes on the new NAS and then use migration assistant to bring everything from the source NAS which is ext4 into the new device. I had the opposite experience. Personally for me, I find btrfs being snappier and faster compared to ext4. I went with ext4 instead of btrfs for the large (50+TB) data volume because of speed, stability and reliability. I hope you have that entertainment library backed up somewhere. Can I upgrade to any of the ds218 series? And what about Btrfs or EXT4? What are the differences and is it possible while upgrading to change from EXT4 (which I believe is used in my old ds213J) and the new Btrfs? Yes, you can simply put your old drives into any new 18 series NAS. Mirror / Raid1. 1. The reason is that you can read anything from anything once in a recovery scenario unless it's encrypted, but the community using the filesystem for a given OS will be largest with the default. My home file share runs zol because I prefer zfs to btrfs and run it at work a lot so I'm much more comfortable with it. Just looking for ways I can boost the performance of docker apps, and the system overall, whilst also changing to btrfs. Now I am in the process of creating new shares and moving the data from the old shares to the new ones that have checksum A community to discuss Synology NAS and networking devices remove the old ext4 volume, create a new btrfs one and finally copy your data back. While it is recommended by Synology that you use the products on this list, you are not required to do so. Heck, even ext4 principal developer recommend btrfs (I’ll add a link when I find it. 7 mdadm version. I assume the best bet for this is to get one of the overpriced Synology RAM sticks so it matches the existing 4GB module already installed? BTRFS vs EXT4. As long as you’re not trying to use it to make complex RAID, it’s a solid choice in the pool of choices. Since I changed the file system to BTRFS here is what I am experiencing: 1. If my synology unit broke and I want to read my files using a external USB HDD reader directly in to my Mac, its better to use what kind of partition? So the DRIVE isn't formatted in BTRFS, the VOLUME that is inside the STORAGE POOL is formatted in BTRFS. On the other hand Btrfs can do it without a hitch because it was designed to I'm familiar with the process of converting from ext4 to Btrfs, as it has been well documented here: How to change from an ext4 volume to a Btrfs volume. I've done some reading and yes I see that it offers a lot more features than ext4 which is an older format on synology but from my understanding on Linux systems ext4 performs much better than btrfs so I dont know if there is some sort of tradeoff here getting loads of features with btrfs but slower read/write speeds than what ext4 offers. I'm liking btrfs for the snapshots as they are very similar to NetApp NAS appliances how they snapshot their volumes at the file I wouldn't worry about btrfs overhead here. I installed arch on btrfs for a test run. They use MD. " Note the hedging/vague words "generally" and "for example". The permanent stream of camera data collides with other data requests, dragging performance down. Welcome to the IPv6 community on Reddit. Plug in external drive to usb (or swap one of the raid disk with the new disk and format it to btrfs). I use lvm snapshots only for the root partition (/var, /home and /boot are on a different partitions) and I have a pacman hook that does a snapshot when doing an upgrade, install or when removing packages (it takes about 2 seconds). I just did a migration from EXT4 to BTRFS. In general, if you’re using a NAS device, you most likely want to use Btrfs for its snapshot and data integrity features. Phones also have flash storage and none of them use EXT4/BTRFS or any other filesystems that were created with HDDs in mind. I followed the instructions from website meticulously and still I can’t see the page choosing ext4 or btrfs. Synology for example uses MDADM for the RAID itself and then uses BTRFS on top (which is a valid option). 4x6TB SHR1 on an ext4 volume, ~8TB of data stored of the available 16. DS920+ running DSM v7. I've read a lot about Btrfs and was just wondering what some of you thought about it, and your experience with Brtfs.

In the process of doing this, I would like to transition to BTRFS so that I can get snapshot benefits. It works perfectly now with no issues. And then delete and reinitialize the drives from old volume to new one. Synology has been doing it this way for long time and has modified btrfs so it can talk to mdadm to fetch redundant copy via mirror or parity(1 attempt) even dual parity (2 attempts) so the self heal part of btrfs still functions Apr 26, 2023 · In general, Btrfs is not as stable as Ext4, though it offers features that Ext4 doesn’t. Nothing else change, i. If you would keep EXT4 in my situation please give a vote down. Tried running VM manager. It absolutely depends on your underlying hardware to respect write barriers, otherwise you'll get corruption on that device since it depends on the copy on write mechanism to maintain atomicity. I'm going to reinstall Artix and I want to make the right choice. Ext4 is fast and rock solid, and easily recovered on a desktop machine if things go really bad. A continuación, os vamos a explicar brevemente las principales características de EXT4 y de Btrfs. But Btrfs has some cool features such as protection against bit-rot and snapshots. This brings up a question, how big is the VOLUME you currently have as EXT4? Is there space to make a new BTRFS volume? If you migrate the shares from one volume to another, you are moving the files from from an EXT volume to a BTRFS volume. For the sake of comparison: Synology uses BTRFS, with snapshots, but it does this by avoiding BTRFS' dodgy RAID5/6 implementation and uses its own. The idea of spanning a file system over multiple physical drives does not appeal to me. Btrfs is a better file system, but you can certainly choose to use Ext4, if you want . It will be used for some normal file sharing for 1 or 2 users as well. 4. ZFS typically benchmarks very well, so long as you have enough system resources. On btrfs it is very fast, - because really, nothing is copied. If there is a way I can use snapshots without btrfs then I would probably be fine to stay on ext4. Even backed it up to 2 separate drives. Btrfs is meant to be like a potential substitute for Ext4, once we reach the theoretical size limit. During the transition, I want to switch to btrfs. Ext4 does not guarantee data consistency. May 25, 2022 · Synology NAS-Systeme bieten generell zwei Dateisysteme an: ext4 und Btrfs. From the side by side comparison it seems like btrfs is way better, but in the more detailed sections the author goes into how it is a bit less mature and that ext4 is more well supported and reliable. 4 TB (which was the maximum available), where it had previously been 32. Backups can be done on either ext4 or btrfs with timeshift I've already read into this issue a bit after being met with the options upon installing EndeavourOS in a VM, but I'd like to hear some more opinions. So, it's conditional. I just had too many broken btrfs stuff in the past years so I don't trust it with my important data. Be careful with all you read about btrfs on the 'net. Nothing new or exciting out it. Reddit is dying You're better off by using "the right tool for the right job". For much heavier DB usage, it's sometimes recommended to make two volumes (on one pool of disks), btrfs for normal usage, and ext4 for high-block-write database usage. Btrfs advantages: It's a CoW file system so copied files take up zero space. A community to discuss Synology NAS and networking devices Ext4 or btrfs? Ext4 has a limit where as btrfs does not. Probably a minor issue, but I know Synology tweaks their Btrfs implementation, and you can't say for certain that VMM would play nicely with another distro's Btrfs configuration. . That however would disable a lot of the Btrfs features. ) Synology doesn't use btrfs-RAID, they use mdadm (linux default) RAID and put a btrfs filesystem on top. No go on ext4. Synology's adaptation bypasses those shortcomings. https://linuxhint. But to be honest, it might be easier for me to work around than the lack of the possibility for single-file clone that btrfs, XFS etc. Yes, btrfs is not as stable as ext4 but I think it's stable enough and is coming along pretty nicely. Hey fellow GNU/Linux enthusiasts, I'd like to know your opinions about using Ext4 vs BTRFS. 2Tb 10. 4Tb available The goal is to convert fully to btrfs. 1) have techniques to reduce the need to defragment. Not sure about BTRFS, haven't had time still (nor interest) to dig into it much. Not relevant to Synology nas as they use btrfs (single data/dup for metadata) on top of mdadm/LVM raid they did some tweaks to btrfs so it can talk to the raid layer to allow self heal to still be attempted Data scrub works fine (triggers a btrfs scrub first if Checksum is enabled when you create the share folders, raid sync afterwards) Hi there! We hope you're doing well! We're an unofficial forum for Synology hardware, software news, discussions, and community support. 0. 5TB of data. Btrfs shines with its data integrity features, snapshots, and error correction, making it ideal for users concerned about data safety. Regarding community: my personal experience is, BTRFS community is smaller, but more prosumers and experts are willing to help. This started as we grew tired of the lack of Moderator involvement in the /r/Synology community, so we decided to take things into our own hands. you can also use the longer legible form of the command that is btrfs subvolume create. In practice, I don't consider the Btrfs slowdown really relevant for desktop usage on an SSD, VM performance aside. Am I right in thinking I can create a new btrfs volume of 10. Synology decided to hack their way around the BTRFS issue by reversing the order of mdraid & lvm2, in such a way that permits disks of different size to be fully utilized in the storage volume. Yay! BTRFS vs. synology "fixed" btrfs raid problems by very simple and effective way: avoiding it completely. I did some research, realize that using BTRFS system could prevent silent corruption and bla bla bla. EXT4 Hi folks, I am looking for your experienced comments! I am preparing to move from a 216j (SHR, ext4) to a 920+. 1-42218 4x14Tb HDD Volume 1 = ext4 27. I use my system in certain ways that makes btrfs a no-brainer for me over ext4, but someone without those reasons has no reason to convert their system to btrfs. I picked up a DS920+ over the weekend and have just got 2 more 3TB drives today. ) Lots of buffering when initially playing, or trying to forward or rewind in a movie The total data in reality was around 49Tib, but btrfs reported the volume as using 55TiB. In some benchmark tests Ext4 has had stronger performance as well. I have also had several system crashes and power failures with no data loss. For my "portable backup" targets, I use btrfs and commandline scripts to send/receive snapshots to the external drive. The only thing that attracts me to Btrfs features is the ability to do versioning on files without much impact on storage vs ext4 where the whole backup is DOUBLED/DUPLICATED at least once first before versioning takes place (thus a 7TB data backed up to NAS results to 14TB initial requirement, too much!) Sure the snapshot creation and rollback ist faster with btrfs but with ext4 on lvm you have a faster filesystem. 4Tb, then move all the apps across to this new volume, remove the large ext4 volume and then expand the 10. Hi! Come and join us at Synology Community. The USB drive is mounted as a shared folder, which means the raw VM disk files would be visible to the user. Btrfs will give you much more, replication, quotas, consistency, Drive versioning disk space saving. Just use ZFS. Took me ~4-5 days of total work, and that was for a 4-bay system with only ~5. What are the advantages and disadvantages of btrfs over ext4, In many tests, ext4 is a bit faster. I let the OS dictate my filesystem. Btrfs sits on top. recreate and restore from backup is all. Synology has fixed Btrfs raid by using Btrfs to detect corruption but MDRAID parity to repair it. From reading the posts here I see that the Synology Migration Assistant will only support migration to the same file system. WD & Windows vs. Btrfs is a bit slower with writes because of its Copy-on-write nature, but just as fast when it comes to reads. Same usage behavior on btrfs I've never had to do anything it just works. Synology maintains a list of compatible devices that they have tested and verified to work with their products. Unix, etc. Rsync is sync, not backup. Synology’s instructions on this process are confusing me. This did NOT affect drives that had been normally formated with btrfs (it only affected drives that had used the ext4 to btrfs conversion tool). I want to make the change for two reasons (1) to be able to run virtual machines and (2) I want to move back to SHR-1. Ext4 is more battle tested, but nowadays most of BTRFS, specifically the RAID-1,10 (but not RAID-5,6) and scrubbing (corruption healing) features are not only production ready, but also used by default by SUSE and Red Hat on Fedora, two heavy weights in the Linux corporate and server space. One wonders why btrfs doesn't just implement this and scrub their attempt at RAID5, since that's (AFAIK) literally the entire feature. 1 to 7. What your doing is more suitable for ext4 file system on Synology due to lack of checksumming on ext4 filesystem, so if the part of the file is corrupted it will still deliver the data quite happily (you have to use manual scans to verify past md5 sum scan to make sure they still match) btrfs or ext4 for DS918+ for surveillance? The primary purpose of a new 918+ is for Surveillance Station with about 6-10 cameras. However with encryption it will be worse, as Synology still doesn't deploy proper full disk encryption. I use many features of btrfs (subvolumes, compression, snapshots, etc. Btrfs takes atomic snapshots (0b instantaneous snapshots that grow in size over time as you delete/edit files). It isn't straightforward to setup under Linux, either. I like btrfs because it does not require a lot of ram like zcache does and you can use dissimilar drive sizes. You can use hyper backup from Btrfs to ext4 but then of course you don’t have bitrot protection. It's unfortunate that Synology defaults to ext4 when formatting external drives. BTRFS it is becoming clear that I should probably convert to BTRFS in the future. Restore data to the Btrfs volume I wonder if it would be possible to copy some Synology binaries to a Linux computer and use them to create DSM 6 style partitions and trick DSM on the NAS into thinking the drive had been migrated from another Synology. Some (such as ZFS, UFS2, ext4, and even NTFS5. Raid1 and 10 are stable with btrfs. client machine, network switch, cables, NAS. Btrfs does by writing checksums of the data. I think you should go with btrfs, btrfs is very stable, the problem is your hardware. As I said, while filesystems can work with SSDs, they don't always use the features that SSDs have. I ended up completing the migration last week, without having to use a backup copy. My questions are: I use BTRFS on Fedora. Hoping to migrate in as automated a way as possible. x. Removed volume. 2. I would like btrfs mainly because I want to utilise snapshots. Depending on why you want btrfs, you could run zfs. When things do go wrong, it does offer recovery options, arguably more in it's No easy way - if you're very comfortable using the commandline and probably not getting support from Synology, you can force btrfs to work on that device - google will find you instructions if you're brave enough. The benefits from Btrfs far outweighs the drawbacks. ) All 4K movies have stuttering/choppy video 2. I understand that btrfs have a major problem with Raid, - and that is a problem. The catch is I have about 40 TB of data on an existing ext4 ( 4-disk, raid 5) volume that I would need to backup first before I convert to a new volume. x got corrupted after updating the kernel to that kernel version 4. Btrfs RAID can be trusted about as far as I could throw Andre the Giant with no arms, so Synology uses mdraid's dm-integrity mode to detect errors instead. I'll make a decision based on the majority. Data is about 8TB. Qnap doesn't support it yet continues to do fine. , USB device, PC, or a remote Synology NAS), or expand the storage capacity by adding extra drives (DSM 7/DSM 6. With hard drives that introduces additional latency on write and read. ). Synology may recognize and keep volume 2 as it was or not but all your data should be on volume 1 anyways as it was part of the backup. I've installed the new drives, and set them up as a new storage pool & volume using Btrfs, and now they're "Optimising in the background". Other useful feature is when you create the share folder you can enable checksum (unfortunately it's usually disabled by default in Synology for some reason and worse can't be enabled after the fact, have to create new share folder and move the data to it) this enables btrfs self heal capability so if a file is damaged it has 1 or 2 (SHR1 or 2) attempts at correcting the file, if it can't I would want to avoid BTRFS and ZFS. BTRFS has many modern features compared to EXT4 (copy-on-write, snapshots, bitrot detection,etc whereas EXT4 has more reliability and performance history. Hi I decided to change my main volume (Volume 1) from EXT4 to BTRFS and just noticed that the Volume size is now only 31. " So yes you have the btrfs filesystem, but it does not control the disks. When I was setting up my device, I couldn’t figure out where to choose btrfs and I end up using ext4 right now. I know very little about the file format but most articles im reading are suggesting Btrfs being preferred. Ext4 is a "pure filesystem" while Btrfs has disk and volume management built-in. Facebook also uses it. H. Reply Basically it's determined by the amount of metadata btrfs ( or ext4) needs and synologys willingness to test things. Conclusion: Btrfs vs. I'd stick with ext4 if the data is critical or important. Daher stellt sich bei vielen die Fragen: Welches ist das richtige Dateisystem für mein NAS? Um das genau beantworten zu können, ist es hilfreich zu wissen, was ein Dateisystem genau ist, welche Dateisysteme es generell gibt und ob sich für den Privatnutzen ein anderes I have an older DS214+ Synology NAS that is running Ext4, and I just ordered a new Synology DS1618+. a large professional setup like in a data center with funding I'd go for zfs. mount the recently formatted btrfs partition without special options just with mount /dev/nvme0n1p2 /mnt and create the subvolumes you want, e. Here's basically all you need to know when choosing Btrfs. Ask a question or start a discussion now. Mount an ext3 drive and you can use most ext4 features but not all - some of them will require a reformat to use. More like EXT4 vs F2FS. Backups can be done on either ext4 or btrfs with timeshift These were formatted in ext4 because Btrfs is unavailable on a DS212.
