Hi:
I have a couple of disks out of a NAS unit that I cannot mount.
They were in a Thecus N2200 NAS
When I look at the in gParted, they happily show up as xfs disks, but when I
rty to mount them, Iget a hole bunch of errors.
Can anyone point me in the right direction on how I can mount these disks to
get the data off them
root@sysresccd /mnt % man xfs_repair
root@sysresccd /mnt % xfs_repair -v /dev/sdb2
xfs_repair: cannot open /dev/sdb2: Device or resource busy
root@sysresccd /mnt % man xfs_repair
root@sysresccd /mnt %
root@sysresccd /mnt % xfs_repair -d /dev/sdb2
Phase 1 - find and verify superblock...
Phase 2 - using internal log
- zero log...
ERROR: The filesystem has valuable metadata changes in a log which needs to
be replayed. Mount the filesystem to replay the log, and unmount it before
re-running xfs_repair. If you are unable to mount the filesystem, then use
the -L option to destroy the log and attempt a repair.
Note that destroying the log may cause corruption -- please attempt a mount
of the filesystem before doing this.
root@sysresccd /mnt % mount -t xfs /dev/sdb2 /nas
mount: /dev/sdb2 already mounted or /nas busy
root@sysresccd /mnt % xfs_repair -L /dev/sdb2
xfs_repair: cannot open /dev/sdb2: Device or resource busy

That usually means the filesystem is mounted. Try unmounting it?
Cheers,
Dave.

Those "hole bunch of errors" may prove useful. Maybe you could share
them with us.
