As mentioned above, when picking between Btrfs vs Ext4 for Synology NAS devices, most users should pick Btrfs for the data integrity benefits that it provides. 2 Replies 1007 Views 0 Likes. Lors de la création d’un volume un NAS Synology, l’utilisateur doit faire un choix. I figured BTRFS was at least a bit of a step up in terms of maintaining data integrity but after TLDR, Synology's implementation of Btrfs should be equivalent to ZFS in protection against bitrot. Protection. It uses the Linux md toolset to build the RAID configuration and then used either ext4 or btrfs for the file system on top of the RAID volume. e. My priority is on data protection over years not on speed. Not sure if and how this translates from DSM 6 days to today, my hunch is Synology's Btrfs implementation is more optimized now than it was at that time. Ce B-Tree est la structure de données qui sert de colonne vertébrale à Btrfs et lui garantit, en théorie, de bonnes performances lors de l'accès et de l'insertion de données (pour ceux à qui ça parle, un arbre-B Share your videos with friends, family, and the world Your btrfs filesystem has some corruption that appears to be causing it not to mount. , single disk, Raid-0, Raid-1, Raid-5 and SHR).

If you’re wondering which file system is the best fit for your needs, you’ve come to the right place. They must be equal to or larger in capacity than the smallest disk currently Installed. Being new to NAS, I only recently found out about Btrfs. The older disks is starting to show signs degradation (reporting bad sectors) so proceeded to order a new disk. Partager Le SHR-2 est un raid 6 (avec un truc en plus permettant de mixer des tailles des disques différentes) avec une tolérance aux panne 2 disques And that’s why you and I didn’t design our own auto sizing redundant disk product 😊 It’s quite simple under the hood - using Linux md to make raid volumes and then using lvm to allow data to be spread across the multiple raid volumes. It's nothing like UnRAID. I can only suppose that I am upgrading to a (8) Seagate Exos 18TB disks and so I am going to migrate all my data out of Synology and reconfigure the unit. (SHR, btrfs, etc. Btrfs uses checksums to detect if a drive returns false data and (assuming Btrfs-Raid is enabled or in the case of synology devices SHR is used underneath (they did something special there)) repair it using data from other drives. This is a quirky FS and we need to stick together if we want to avoid headaches! There are no dumb questions and all discussion is The Synology Btrfs should not be confused with SHR as Btrfs is more of a file system (that allows replication and/or “shadow copies” within the Synology NAS). unclear if a Windows or Mac system with EXT4 or BTRFS file system support could do this as well). It will make multiple RAID configs to make most use of extra space on larger disks. Data will be transferred over, and the btrfs vs exfat thing will be handled by the software. This makes it ideal for archiving and maintaining regulatory compliance. SHR can be considered a "idiot-proof" RAID for Synology NAS especially if you cannot convince yourself to use RAID 5 (on SSDs), RAID 6 or RAID 10 and then add 1 or 2 hot spares. Gibt es da für BTRFS einen zuverlässigen Treiber? 3. Both NAS and DAS utilise RAID as a During the transition, I want to switch to btrfs. Btrfs: Which Linux File System Should You Use?

Aktuell ist ein SHR (Raid5) geplant. Сабж в названии темы. I will go with btrfs. A) 不用 btrfs, 直接舊的兩顆 ext4 搬到新 NAS 上繼續使用 ext4 (這個應該最簡單) B) 使用 btrfs, 但是不確定這樣做對不對: i) 新 NAS 裝兩個新 4TB 硬碟先初始化成 btrfs, 做 SHR ii) 從舊 NAS 把資料透過網路 copy 到新 NAS 上. The permanent stream of camera data collides with other data requests, dragging performance down. Especially if it means you have to pick SHR-1 over 2. md allows converting from RAID-1 mirroring to RAID-5 without data loss, so that’s why it can grow. SHR is more flexible as it can combine partitions together seemlessly. So konnte ich per "Timeshift" vergleichsweise kleine Snapshots meines Systems Posted by u/danuwaanalih - 1 vote and 3 comments No, that's the whole point of using shr, not being bound by the smallest drive. 4.

Once you‘ve added enough disks for redundancy, all extra disks just add storage space without being used for redundancy. (Obviously ZFS has a host of other handy features, but Synology has the handy feature of SHR. Aside from upgrading with different sizes, if you use BTRFS an added benefit to SHR1 is that it can repair file-system bit-rot using the RAID's parity. LAN 케이블을 공유기에 연결한 후 NAS 전원 켜기3. Btrfs runs on top of whatever RAID you're using. If your DSM version is 7. iii) 舊 NAS 硬碟搬到新 NAS 上重新格式化成 btrfs The only reason to make separate storage pools is if you're using a different type of drive for them (SSD vs spinning, or A/V-optimized vs general-use). Finally, out of frustration, I wiped my NAS and now have one EXT4 volume for most things and one BTRFS volume for my Virtual Machines.

RAID6 in 1819+ Hey all - currently have a DS1819+ with (8) 4TB WD Red disks in "RAID6" on EXT4 filesystem. 1, use the Btrfs (Peta Volume) file system instead. The write hole problem in btrfs presents only if you're using raid 5/6 for metadata (and possibly system data, I'm not 100% certain there,) which is recommended against in favor of mdata raid1 due to the small size and the importance of metadata in detecting and healing checksum failures of data, even if you're using raid5/6 for data. Hopefully md raid under BTRFS. Shr-2 is faster, and the connection is excellent even over a long distance. On the other hand there will probably be no benefit at all if you Btrfs เป็นระบบไฟล์ใหม่ล่าสุดที่ทำให้แน่ใจได้ว่าข้อมูลจะมีความสมบูรณ์ในระดับสูง F1 และ SHR Synology uses normal lvm/mdadm + btrfs (not proprietary even when using SHR witch is basically raid with slices to allow different size drives to be used, can be mounted on old copy of ubunto witch Synology provide) It is true Synology has made some custom code that allows for communication between BTRFS and MDADM/LVM to perform automatic DS1512+ btrfs ? Raid10 vs SHR2 DS1512+ btrfs ? Raid10 vs SHR2. The question BTRFS is my choice. Launched in 2009, this filesystem was intended to offer a copy-on-write mechanism and prioritize data integrity, while integrating features for RAID and other advanced actions practiced by Linux system admins.

By the way, as far as I know, BTRFS and data scrubbing is available on RAID-5 and RAID-6 arrays. In comparing SHR to, say, RAID 5 or RAID 6, you state that SHR has the advantage that the data is accessible even after a drive failure, whereas with a RAID configuration the data is inaccessible. You can get expansion on the fly with RAID5 or 6, too. 与其他文件系统相比，Btrfs具有更大的灵活性和更少的风险。Btrfs支持多种数据压缩算法和多种RAID级别，这使得使用者可以根据自己的需求选择最合适的配置。此外，Btrfs的文件系统层可以在系统崩溃或重新启动时保持完整性，这意味着文件系统可以更容易地恢复。 Btrfs supports this feature as of DSM 7.

If raid5 and shr1 were exactly the same, there would be little use for a calculator. I will probably change it to RAID 1 from here on out, as I just read that BTRFS doesn't support SHR as far as all the file-system anti-corruption methods go. I was revisiting the subject and I think I have taken few btrfs and DSM functions and linked them with SHR. Synology make use of regular Linux MDADM RAID with BTRFS on top (with some secret sauce drive mapping 群晖的 btrfs 是2015~2016随 DSM 6 发布全面引入的，在这之前几年btrfs就已经能用于生产环境了。可以用，稳定性不错，我用了十年群晖了，一直是这样用没出现问题，半年做一次校验可以接受的。 尤其是SHR模式，可以用btrfs大大提高安全性。 Ich bin seit Mitte 2023 auf Linux unterwegs. Then, EXT4 was marginally faster with sequential data, while Btrfs was marginally faster with random read access (both with "generic" RAID generally faster than SHR). Some of the interesting features offered by btrfs include: 1) Support for huge files. 하드디스크(8TB 2개)를 NAS에 장착2. Member; 108 Share #1 Posted April 23, 2017.

Choosing BTRFS over EXT4 will add an extra bit to the data security. Btrfs wird aktuell nur The choice between SHR and SHR-2 depends on your specific needs for data protection, the number of drives in your NAS, and the criticality of your data. So your typical shr setup could have several raid5's under the hood. Choosing a legacy filesystem like ext4 over a modern copy-on-write system like btrfs in 2018 because you're afraid of losing data seems like madness to me. SHR with 3+ drives all matching is RAID 5. You do this by adding disk in the 'Change RAID-type' menu. a. Regarding your EDIT1: that's a RAID10 pretty much. SHR-2 would provide functionality similar to RAID 6.

We also provide useful information about Btrfs or EXT4 for Synology NAS devices Khi phát hiện ra sự không phù hợp (hỏng dữ liệu ngầm), Btrfs có thể tự động phát hiện các tệp bị hỏng, so sánh dữ liệu được sao chép lúc đầu và khôi phục dữ liệu bị hỏng bằng cách sử dụng các RAID được hỗ trợ, bao gồm RAID (1, 5, 6, 10, F1) và SHR-1, SHR-2.
