May 2May 2 I'm in the process of setting up a new array, and I'm wondering if there's any reason toa) use a filesystem other than XFS andb) not use encryption
May 3May 3 Community Expert a) Depends on how worried you are about bit-rot (it is not that common in the real world although many people are paranoid about it). XFS is probably the most stable option but does not include detecting bit-rot, whereas BTRFS (the other sensible option) does. however with XFS you can use the File Integrity plugin to automatically create checksums which can be used to file corruption. If you DO get file corruption you need to have backups to recover or be able to get the file(s) involved again.b) The downside to any encryption is that if you have file system problems it makes it much harder to recover all data intact. You have not stated why you want to use it? It really only protects against those who have physical access to the drives while Unraid is not running but that might be the reason you want it.

I had thought that if I provide the encryption key to the technician working on the drive then it should be no more difficult than recovering data from an unencrypted drive, but perhaps that was naive of me?[Edit] To answer your question, I don't have a particularly strong reason for wanting encryption - it simply makes disposing of an old/dying/dead drive simple and hammer-free.
