Hi,

Finally, this problem be fixed:)

This problem in my TODO list for long time, always no time to do
that(because it doesn't impact many test machines). This
patch looks good, but still more others problems cause by
mutil-strip device. Likes:

1. mkfs warning:
+Warning: AG size is a multiple of stripe width.  This can cause performance
+problems by aligning all AGs on the same disk.  To avoid this, run mkfs with
+an AG size that is one stripe unit smaller, for example 1966016.

2. some cases depand on some certain sunit.

Are you planning to fix them all? Or only this one?

Thanks,
Zorro
