Thanks for your suggestion. 
My concern is that whether my current XFS 1.0.1 release may
lose data for files opened as read-only. Someone has seen once or twice that
"fstab" is corrupted after power off. I know XFS 1.1 has made
lots of enhancements, is it ever possible this also happens
with XFS 1.1? 

Can anyone give a clear answer on this for both 1.0.1 and 1.1? Thanks.
