# The rgmanager resource agent in rgmanager/src/resources/nfsserver.sh.in
# did the unshare for gssd and idmapd as well, even though it seems unclear why.
# Let's start with just the nfs-server, and add others if/when we have clear

The nfsserver resource agent offloads the start/stop/monitor

nfsserver varies on different Linux distro. In the event that this

this location, ${DEFAULT_INIT_SCRIPT}, or detect a systemd unit-file
to use in the event that no init script is detected.

RFC8881, 8.4.2.1 State Reclaim:
If the server scope is different, the client should not attempt to
reclaim locks. In this situation, no lock reclaim is possible.
Any attempt to re-obtain the locks with non-reclaim operations is
problematic since there is no guarantee that the existing
filehandles will be recognized by the new server, or that if
recognized, they denote the same objects. It is best to treat the
locks as having been revoked by the reconfiguration event.
For lock reclaim to even be attempted, we have to define and set the same
server scope for NFSD on all cluster nodes in the NFS failover cluster.
This agent won't "guess" a suitable server scope name for you, you need to
explicitly specify this. But without it, NFSv4 lock reclaim after failover
won't work properly. Suggested value: the failover "service IP".
