Snapraid.

SnapRAID is an easy, software RAID system for Windows and Linux systems that allows users to set up a drive pool to house data easily. The program is free of charge, is open source, and runs on most Linux operating system with ease. In this tutorial, we’ll be focusing on setting up SnapRAID on Ubuntu server.20 May 2019 ...

On the most basic level, it offers protection to the contents of a file-system …With SNAPRAID, just note that scrubs, fixing silent corruption, and other maintenance processes are not automatic. You'll need to schedule commands such as snapraid sync, snapraid scrub and snapraid -e fix. These commands can be scheduled in the GUI using Scheduled Jobs, where the output can be E-mailed to you.

So I decided to look into MergerFS and SnapRAID. The install is really easy (and well laid out in the above linked-to posts). Essentially, it’s 1) install MergerFS, 2) figure out the drive serial IDs, 3) create directories for the mount points (including one for the “usable” mount point, 4) edit fstab to mount the drives, and 5) run mount ...Second option: I think maybe it`s good idea to add my nvme to mergeFS pool as first drive, change policy to "Existing path - first found" (because now I have "Most free space") and setup "Minimum free space" as 25% of nvme space. My idea that all data will be writen to nvme till it will be filled in for 75%, …Only then should you shut down the machine and physically remove the drive and restart the machine. At this point if OMV starts throwing errors about a now missing drive or filesystem or shares, etc. you must solve those problems before continuing with the snapraid recovery step. I told you what to change in the snapraid.conf file.

I'm doing some experiments with a OMV VM with mergerfs + snapraid. I created 4 x 60GiB virtual disk. Three of them were merged in one mergerfs disk with policy: Most free space. I configured snapraid with the same 3 data disk e 1 parity disk. Then I copied about 30 GiB of files inside the shared merged disk. Then I made the first sync.

If the disk was completely empty you can just put a hashtag to comment out the line from config like this: #disk d2 F:\PoolPart.ad2f4be6-a6e1-4d79-b99a-9329a37be308\. And run sync. If it was not completely empty you first need to point d2 to an empty folder like this: disk d2 F:\SomeEmptyFolder\. And run …I am running an almost identical configuration to what you quoted having just (in the last week) switched from omv snapraid script to the snapraid btrfs python driver script used in that page. I currently have 4 data drives and 2 parity drives and all drives have a /merged subdirectory that is connected with mergerfs.One advantage of SnapRAID is that it uses fewer disks (1 parity for up to 4 data drives, 2 parity for up to 14 data drives, 3 parity up to 21 data drives, etc). But more importantly, using parity it also can protect against file corruption, something folder or pool duplication on DrivePool cannot.SnapRAID won't be able to properly detect the UUID when using a snapshot, so it won't be able to use inodes to detect move operations. As a workaround, you can temporarily disable snapraid-btrfs, either globally by doing a regular snapraid sync, or for specific drives by doing a snapraid-btrfs sync using the -U option to select snapshot 0 (i.e ...

I have a somewhat peculiar installation (see this for a common problem ZFS users have) with ZFS (via openmediavault-zfs 5.0.6) in the mix on OMV 5 with MergerFS (via openmediavault-unionfilesystems 5.1.4) and SnapRAID (via openmediavault-snapraid 5.0.8).I've kinda set-it-and-forgot-it due to a lot of crazy world life stuff, but I believe it's …

Or sometime you might run a "snapraid scrub" before you "snapraid sync" and lose all your changes. In this case, you can snapshot your top level archive before running "snapraid scrub" and if something goes wrong you can always remount the snapshot and recover gracefully. There is a script "snapraid-btrfs" that uses snapper to …

SnapRAID stores the list and check-sums of your files in the content file. It's a binary file, listing all the files present in your disk array, with all the check-sums to verify their integrity.

In the past, adding larger data disk always came with the issue of needing parity disks as large or larger than your data disks. For example, let’s say you add …In other words with enterprise drives it is OK to scrub 100% every week and for cheaper drives like Seagate archive and WD Green/Red you should probably try to stay below 40% per week and even less if you also have other significant workload on the disks. Scrubing 100% every few months is definitely …SnapRAID will fix the parity. With two parities, SnapRAID will also be able handle the case of a missing or corrupt file. SnapRAID always does the right thing because it keeps hashes of all the files, and it knows what is correct and what is not. This is one of the main difference with unRAID. Ciao, Andrea

linuxserver/snapraid. SnapRAID is an application which computes parity across a set of hard drives (usually in JBOD configuration) allowing recovery from drive failure. It is known as a ‘snapshot’ RAID implementation meaning that it is not ‘real-time’ such as mdadm, ZFS or unRAID. It is free and open source under a GPL v3 license.Raspberry Pi NAS - Streamline setting up your home NAS (up to 128TB data on RPI 4B 8GB) with VPN remote access and automatic computer-to-computer sync by combining Snapraid, Mergerfs, Hamachi & Syncthing using bash install scripts and preconfigured config files to minimise manual input. syncthing …

It seems to me that SnapRaid should have recognized that the CRC for the files was already good and that it was the parity that was at fault. Failing that, it should have recognized that the parity data was unreadable and not attempted to repair the data at all.

It is stored in files, so if you change of hard drive, you just have to copy these parity files to the new one. You can exclude some folders if you don't want to generate parity for them. This is why SnapRAID is better suited for data that rarely change. On the other hand, newly added files don't prevent recovering already existing files. You may only lose the recently added files, if they are on the failed disk. Other SnapRAID limitations are: With SnapRAID, you still have separate file-systems for each disk.Snapraid would in that case consider the file to be modified and snapraid won't be able use that file to restore other files on other data disks until after you have synced again.
