NAME
       clurmtabd - Cluster NFS Remote Mount Table Daemon

DESCRIPTION
       Instances  of clurmtabd keep entries relevant to a given mount point in
       sync cluster-wide.  It does this by polling /var/lib/nfs/rmtab periodi‐
       cally.

HOW IT WORKS
       A  single  instance  of	clurmtabd  is  spawned	by the service manager
       (clusvcmgrd(8)) for each mount point in a  given	 user  service.	  Each
       instance	 polls	/var/lib/nfs/rmtab  every  few	seconds,  looking  for
       changes.	 When changes are detected, they are merged in with  the  cur‐
       rent  in-memory	view.  The entries are filtered according to the mount
       point being monitored and are subsequently written out synchronously to
       that mount point.

       When  a	user  service  is  relocated (or after a fail-over), clurmtabd
       reads the entries on a given mount point and synchronizes them with the
       new  member's  /var/lib/nfs/rmtab.   This  is done prior to running the
       exportfs(8) command so that clients of the given service do not receive
       "Stale NFS file handle" errors.

NOTES
       Clurmtabd  is not a part of NFS and can not ensure that "Stale NFS file
       handle" errors are never received.  It is a  best-effort	 attempt.   To
       fully prevent "Stale NFS file handle" errors, it is necessary to modify
       the Linux kernel as well as nfs-utils.
