testing luci removal of nodes feature in a 2 nodes cluster + qdiskd:
remove node 2:
Message from syslogd@rhel6-node1 at Jul 20 12:09:49 ...
rgmanager: #1: Quorum Dissolved
left me a bit puzzled because qdisk is running but:
[root@rhel6-node1 ~]# cman_tool status
Config Version: 5
Cluster Name: fabbione
Cluster Id: 17126
Cluster Member: Yes
Cluster Generation: 20
Membership state: Cluster-Member
Expected votes: 1
Quorum device votes: 0
Total votes: 1
Node votes: 1
Quorum: 2 Activity blocked
it looks like qdiskd is voting 0 _probably_ because of the autovote calculation.
That sounds accurate.
