Hi there!
Recently due to a power failure, my self-built NAS was shut down by force and when I tried to boot it up today, I could not access my RAID anymore. First of all some tech specs:
- OMV 5.6.26-1 Usul
- btrfs filesystem
- 4 drives in a RAID which now fails to be mounted
When trying to mount the filesystem, I'm getting this error:
Fehler #0:
OMV\ExecException: Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; mount -v --source '/dev/disk/by-id/md-name-myNAS:myNAS' 2>&1' with exit code '32': mount: /srv/dev-disk-by-label-data: wrong fs type, bad option, bad superblock on /dev/md127, missing codepage or helper program, or other error. in /usr/share/php/openmediavault/system/process.inc:196
Stack trace:

#5 /usr/sbin/omv-engined(537): OMV\Rpc\Rpc::call('FileSystemMgmt', 'mount', Array, Array, 1)

Any suggestions how I could save the filesystem and get back access to the files? I'll do my best to perform any step needed, but I'm not very familiar with the CLI, so please provide the needed commands and arguments if possible.
Thank you for any help
