ganesha/scripts : delete nfs-ganesha folder from shared storage during clean up

2016-06-24T00:48:38+00:00

A directory named "nfs-ganesha" will be created inside shared storage when
'gluster nfs-ganesha enable' is executed. Similarly this directory should be
removed when 'gluster nfs-ganesha disable' is executed.

common-ha: race/timing issue setting up cluster

2016-06-04T04:10:02+00:00

The ganesha_grace resource agent can start before the ganesha_mon
resource agent, with the result that the crm_attribute that
ganesha_grace expects to find has not been created yet.

This is never (never? Or just so rarely that it has never actually
been seen during development) seen with four nodes, but with just
two nodes it's very repeatable.

Note that when long (FQDN) names are used it is not unexpected to
see Failed Actions in the output of `pcs status`, e.g.:

* nfs-grace_monitor_5000 on node1.fully.qualified.domain.name.com
'unknown error' (1): call=20, status=complete, exitreason='none',
last-rc-change='Wed Jun  1 12:32:32 2016', queued=0ms, exec=0ms
* nfs-grace_monitor_5000 on node2.fully.qualified.domain.name.com
'unknown error' (1): call=18, status=complete, exitreason='none',
last-rc-change='Wed Jun  1 12:32:42 2016', queued=0ms, exec=0ms

and as long as all the ganesha_grace_clone and cluster_ip-1
resource agents are in Started state then this is okay.

common-ha: wait for cluster to elect DC before accessing CIB

2016-05-24T09:35:58+00:00

access attempts, e.g. `pcs property set stonith-enabled=false`
will fail (or time out) if attempted "too early", i.e. before
the cluster has elected its DC.

common-ha: post fail-back, ganesha.nfsds are not put into NFS-GRACE

2016-05-24T08:41:18+00:00

A little known, rarely used feature of pacemaker called
"notification" is used to follow the status of the ganesha.nfsds
in the cluster. This is done with location constraints and other
Black Magick.

When a nfsd dies, the ganesha-active attribute is cleared, the
associated floating IP (VIP) fails over to another node, and the
ganesha_grace notify method is invoked with post-stop on all the
nodes where the ganesha.nfsd is still running. The notify methods
send dbus msgs to put their nfsds into NFS-GRACE, and the nfsds
perform their grace processing, e.g. taking over locks from the
failed nfsd.

N.B. Fail-back was originally not planned to be a feature for
glusterfs-3.7, but we sorta got it for free.

For fail-back, the opposite occurs. The ganesha-active attribute
is recreated, the floating IP fails back, and the notify method is
invoked with pre-start on all the nodes where the surviving
ganesha.nfsds continue to run. The notify methods send dbus msgs
again to put their nsfds into NFS-GRACE again, and the nfsds clean
up their locks.

Setting the option too early results in an error in newer versions
of pacemaker. Postpone setting the option in order for it to succeed.

N.B. We do not use a fencing agent. Yes, we know this is not supported.
