after moving filesystem from one physical location to another, we are
experiencing /subj errors.  Filesystem is located on LVM2 volume on SCSI
RAID10.  We did dd old_system new_system and used xfs_growfs to enlarge
filesystem to match physical location.

Full error is:
Filesystem "dm-3": corrupt dinode 204364567, extent total = 6, nblocks = 0.  
Unmount and run xfs_repair.

Our current plan is to add another SCSI RAID10 volume to system and use
xfs_dump/restore (xfs_copy) to do a logical (not physical) copy of

And if there is some quicker way how to fix this error (I haven't found
an solution using archive)?  It seems that there definetely exists bug

(0. moving filesystem)
1. using LVM
2. using xfs_growfs
