Perhaps: 1) A remote machine has a mount of /mnt/md0 2) Your server has a stale mount record for /mnt/md0 3) Something has wacked out lockd, which is keeping stuff locked Try "showmount" and see if any machines have your filesystems mounted when you think they shouldn't. If some machine has a stale NFS mount, you may need to clear out the saved statd information. Ross Vandegrift ross@willow.seitz.com
