Snapraid.

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%, …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 calculates parity to recover data if a drive fails. They work well together to replicate a similar type of " JBOD parity" system as unraid uses. The difference here being that unraid does the parity calculations in real-time (and therefore seriously hurts write performance) vs SnapRAID which does the calcuations on a timed basis every X time …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 …Here is my /etc/snapraid.conf file, edit it as you see fit – it is fairly self explanatory but you do need to make sure each drive is individually mounted in /etc/fstab. # Example configuration for snapraid # Defines the file to use as parity storage # It must NOT be in a data disk # Format: "parity FILE_PATH" parity /mnt/parity1/snapraid ...

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.

Insert drive in DrivePool, then stop service to move files to the new poolpart folder, restart service and remeasure pool. Edit Snapraid config to replace the old drive by the new.

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. C :\ All Data>snapraid scrub -p full Self test ...

To get set up, first you need to download and compile SnapRAID, so let's get Debian based Linux OS ready by ensuring we're up to date, and have gcc, git, and make installed: sudo apt-get update. sudo apt-get upgrade. sudo apt-get install gcc git make -y. Now let's download, compile and install: cd ~/Downloads.

Summary. SnapRAID is a backup program for JBOD disk arrays. SnapRAID stores data parity information which enables the recovery of disk failures. SnapRAID is targeted toward home media centers, with a lot of large files that rarely change. However, SnapRAID works well in similar environments were data stores are largely static.One forum site said to use snapraid -c snapraid.content to see the drives and figure out where the issue is. sudo snapraid -C snapraid.content.

Snapshot: Real-time: Real-time Snapshot: Real-time Snapshot: Real-time Snapshot: Real-time: Integrity If data is validated with some kind of checksum, and which one is the default. YesFor recovery you need all the data on all the disks (plus parity) as they were at the last sync (that's snapshot part). And of course minues 1 of any disk per parity. But if you make changes and you can't revert those changes (revert your txt) then SnapRAID is useless for you. That's why it's also a good practice to not delete files you want to ...You can use Snapraid-btrfs wrapper (and Snapraid-btrfs-runner script). Snapraid-btrfs will create read only snapshots of each drive/subvolume (it's instant) before each sync. This way you will never sync the live filesystem. This also overcomes the biggest downside of snapraid: if files are modified between syncs, you can't restore!Two of the biggest perks of using SnapRAID/MergerFS over standard RAID is the fact that the data is directly on the physical disk and can be moved to another system in tact which is impossible in a RAID. The other is that you can use multiple disk sizes with SnapRAID/MergerFS and grow without too much difficulty.

So I have a 24 bay Computer case and have 24 x 8TB drives. Previously I had my Data Drives as a mix of 8TB and 4TB and my Parity Drives as all 4TB. I was doing Triple Parity and had 2 x 4TB drives per parity. Have Moved over to 8TB Parity drives and was still using 2 x 8TB per parity for the triple parity and noticed it's only filling …SnapRAID will have trouble repairing files where the parity info is mixed with that deleted data, until the next sync. (Although, I understand, SnapRAID can still use the moved data even it's on another drive.) But mainly, constantly moving files - especially when you can avoid it - isn't a good thing for best recoverability.

Snapraid is like raid 5 (or 6) and needs at least 3 drives. If you only have two drives, you would be better offer to have a scheduled rsync to sync the two drives together. With unionfs, you would never want your parity disk in the pool. So, if you want backup (highly recommended), you shouldn't pool anything until you get more drives.So I have a 24 bay Computer case and have 24 x 8TB drives.

SnapRAID doesn't care about MergerFS. MergerFS creates a "storage pool" from the data drives, that you can read and write to like a normal drive. It passes these reads and writes through to the data drives, where the files are actually stored. MergerFS doesn't care about SnapRAID.Snapraid looks for its configuration in /etc/snapraid.conf. The Ubuntu package already comes with a default configuration, which still requires the following additions: disk: the mountpoint of the disks you wish to protect; parity: the absolute path of the file where the parity information will be stored.Karachi-based SnappRetail wants to help Pakistan’s kiryanas digitize all their operations, while also providing micro-loans.

These errors are reported in the "scrub" result, but related blocks are not marked as bad. The 30 removed files is probably screwing it up.
