Did that a few times already, and the fs is getting mounted during boot 
anyway, but xfs_check still complains:

--------------------------------------
# xfs_check /dev/mapper/md3 2>&1 | tee fsck_md3.log

The fs is ~138 GB in size. I shall run a backup and then just let 
xfs_repair have its way. I just thought you guys might have an idea what 
these messages are about and why mounting the fs (Thanks, Dave) does not 
seem to care.
