- I don't think the original question was in reference to shared writes
- between VMS and UNIX. I think it was coordination between members of a
- cluster writing to NFS client files that they all can see. Since the
- cluster members don't see the same device (apparently you cannot mount
- NFS devices cluster-wide?) you probably don't get cluster-wide distributed
- lock-manager locking to coordinate shared writes amongst cluster members,
- right? In other words, it doesn't act like a physical disk with multiple
- paths or a single-path disk device served to the cluster and mounted
- cluster-wide.
-
- Would be neat if I'm wrong.
