March 7, 20233 yr Hey everyone, I am preparing to migrate my server to unraid, so I am testing some fail safes. My test was: Open unraid, format a usb stick as XFS encrypted on a debian I am decrypt with `sudo cryptsetup open /dev/sdd1 luksrecoverytarget -- type luks` and it is actually mapping it to `/dev/mapper/luksrecoverytarget` Now the problem is to mount it... `sudo mount /dev/mapper/luksrecoverytarget /tmp/data/` returns: mount: /tmp/data: wrong fs type, bad option, bad superblock on /dev/mapper/luksrecoverytarget, missing codepage or helper program, or other error. And more debugging here: sudo xfs_repair /dev/mapper/luksrecoverytarget Phase 1 - find and verify superblock... Superblock has unknown compat/rocompat/incompat features (0x0/0x8/0x8). Using a more recent xfs_repair is recommended. Found unsupported filesystem features. Exiting now. sudo xfs_db -c uuid /dev/mapper/luksrecoverytarget Superblock has unknown read-only compatible features (0x8) enabled. Attempted to mount read-only compatible filesystem read-write. Filesystem can only be safely mounted read only. can't read superblock for AG 0 failed to read UUID from AG 0 cache_purge: shake on cache 0x2399920 left 1 nodes!? cache_purge: shake on cache 0x2399920 left 1 nodes!? cache_zero_check: refcount is 1, not zero (node=0x23ae0d0) Any idea ? I am getting scared and probably will abort my plan to migrate to unraid.
March 7, 20233 yr Community Expert It is not clear to me where the formatting and reading are taking place? I would expect you to be partitioning and formatting on the Unraid side to ensure the partitioning conforms to Unraid standards. You should then be trying to read this on the Debian system to prove it can be read outside Unraid. Your narrative suggests you might be trying the other way around?

Sorry I skipped that step on my text. Yes, the preparation was: I added the pendrive to a unraid installation with no disks! I added the pendrive to disk 1, choose XFS encrypted, and I started the array! After that I shut it down and then I am now trying to open the disk outside of unraid.

This suggests you are using an older and incompatible xfs progs, you can always boot using an Unraid trial key on a different computer and mount the disks there.
March 9, 20233 yr Community Expert Works fine on ubuntu for me. Don't even have to fiddle with the command line, plug it in, window pops up asking for passphrase, enter it, mounted. Edited March 9, 20233 yr by Kilrah
