Just FYI, starting with 2.6.30 or 31-rcx you no longer get that message
on a xfs->lvm->raid-5 setup. I am not sure if this is because lvm
says it supports barriers or an XFS issue.
This does not seem to be an uncommon setup so getting this working in
the long run would be nice.
Kind regards,
Michael
