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

2016-05-24T09:36:44+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.

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

2016-05-24T09:36:31+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: stonith-enabled option set error in new pacemaker

2016-05-19T10:17:30+00:00

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."

glusterd-ganesha : copy ganesha export configuration files during reboot

2016-05-06T12:59:44+00:00

glusterd creates export conf file for ganesha using hook script during
volume start and ganesha_manage_export() for volume set command. But this
routine is not added in glusterd restart scenario.
Consider the following case, in a three node cluster a volume got exported
via ganesha while one of the node is offline(glusterd is not running).
When the node comes back online, that volume is not exported on that node
due to the above mentioned issue.
Also I have removed unused variables from glusterd_handle_ganesha_op()
For this patch to work pcs cluster should running on that be node.
