mount -t xfs -o loop,offset=11403264,ro,norecovery /dev/md0 /lost
gives me a mount(!!):
df -> /lost/public, but it's not a standard entry:
?--------- ? ? ? ? ? /lost/public
and dmesg coughs up many lines of XFS errors:
loop: AES key scrubbing enabled
loop: loaded (max 8 devices)
Filesystem "loop0": Disabling barriers, not supported by the
underlying device
Mounting filesystem "loop0" in no-recovery mode. Filesystem will be
inconsistent.

fs/xfs/xfs_rw.c. Return address = 0xfb2fc728
Filesystem "loop0": I/O Error Detected. Shutting down filesystem:

Please umount the filesystem, and rectify the problem(s)
