Hello Justin,

since xfs_repair works independently of the in-kernel XFS implementation 
it is possible to repair a directory-corruption broken XFS filesystem 
with Knoppix 5.0.1.

It did so already. I used 5.0.1 to rsync a workstation image and sure it 
had this slight corruption afterwards. Thus I xfs_repair'ed it and 
xfs_check'ed it afterwards and all was well again.

No this is not a recommendation to use Knoppix 5.0.1 to rsync an 
workstation image ;), but an xfs_repair should be possible (unless one 
hits the unfixable bug). 

Important: When XFS needs to be mounted first before repair in order to 
clean the log it might not be wise to use Knoppix 5.0.1 tough.

BTW when using Knoppix 5 or even an older version instead I recommend 
switching off the write cache to be on the safe side (hdparm -W0).
