I use Samba / XFS / xfsdump with SUSE 9.0 at the office, so I know it
works with the 2.4 kernel.

If I had to guess, your /srv/shares/pdoxdata directory is not a mount point.

xfsdump works on an entire filesystem/partition.  I don't think is
allows dumping of a directory tree.

ie. The last arg of xfsdump has to be a mount point to my knowledge.
