Hi all,

I was just browsing redhat.com when I struck the following
http://www.redhat.com/docs/manuals/linux/RHL-8.0-Manual/admin-primer/s1-disa
ster-backups.html. Basically linux says stay well away from dump when using
ext2 and ext3 when using any kernels 2.4.x and above. As he says the cause
of this is that the page and buffer cache are no longer coherent, I am
wondering if this also applies to xfs filesystems and xfsdump/xfsrestore;
they use the same caches, right?
If this _does_ apply to xfs then I guess dump is out the window even on xfs
filesystems, which would really be a pain as I prefer [xfs]dump over tar or
cpio by a mile.
Many thanks for any answers,

Kai.
