These pairs could be pinged and/or tested before the Filesystem RA tries to
connect to them. In case that one of these nodes is not reachable or does
not respond to the connection attempt the RA could try a connection with
the next nvpair.
Background:
I would like to build a openais/pacemaker cluster consisting of three nodes.
On each node should run a gluster server providing a replicated glusterfs
share, a glusterfs client (Filesystem RA clone) connected to this share and
one or more KVM-VMs=20
Due to load reason the VMs should be distributed over the cluster. In case
of crash of one of these servers the affected VM shall fail over to the
remaining nodes.
I hope I was able to explain my concerns and you or anybody else could give
me a hint to solve my problem.
Thx in advance
Uwe

ACK, that''s why we use this shared IP (e.g. for backup issues via nfs).
AFAIR glusterFS retrieves Volfile (via shared IP) and connects to the nodes.
