Cool! Would you by any chance have information on the interaction
between journal filesystems with write barrier functionality, and
software RAID (md)? Based on my experience with 2.6.17, XFS detects that
the underlying software RAID 1 device does not support barriers and
therefore disables that functionality.
Cheers!
