Maybe my original email was unclear, but this is an NFS server, not a
client. Why would an NFS exported filesystem hang xfsdump? (or even du -k
?)
ie.

 1149 ?        D      2:21 xfsdump -F -J -l 1 - /dev/md4

This xfsdump is trying to dump /dev/md4 which is obviously local to the
server and it's stuck. Why is it stuck? /dev/md4 itself doesn't appear to
be stuck, as I can access files on it both locally and via NFS mounts on
other Linux boxes (and samba mounts on Win boxes)

BTW: It's a Debian server (3.0 with security updates, I downloaded and
compiled xfsprogs and xfsdump rather than use the supplied Debian ones)
It's running a stock 2.4.21 kernel patched with Alan Coxes ac4 patches
which include XFS. I've heard that these patches are "old" though. Right
now I have lots more processes stuck in D state so I'll have to reboot it
in the morning.

Tomorow, I'll see what the latest snapshot patches on 2.4.21 do, if
nothing better then it's back to ext2 for this partucular box )-:
