'clustat' and 'cman_tool nodes' show the quorum disk as offline on non-master nodes when using master_wins in RHEL 5

Solution Unverified - Updated -

Issue

  • The quorum device appears as "offline" in clustat output on the second node of my cluster:
[root@jrummy5-2 ~]# clustat
Cluster Status for jrummy5 @ Fri Feb  1 08:59:43 2013
Member Status: Quorate

 Member Name                                 ID   Status
 ------ ----                                 ---- ------
 jrummy5-1-clust.ruemker.pvt                     1 Online
 jrummy5-2-clust.ruemker.pvt                     2 Online, Local
 /dev/dm-3                                       0 Offline, Quorum Disk
  • cman_tool nodes shows the quorum device with an "x" (offline) on the non-master node in the cluster:
[root@jrummy5-2 ~]# cman_tool nodes
Node  Sts   Inc   Joined               Name
   0   X      0                        /dev/dm-3
   1   M   9736   2013-02-01 08:58:55  jrummy5-1-clust.ruemker.pvt
   2   M   9732   2013-02-01 08:58:55  jrummy5-2-clust.ruemker.pvt
  • cman_tool status shows "Quorum device votes" on the first node in my cluster, but not the second:
[root@jrummy5-1 ~]# cman_tool status | grep "Quorum device"
Quorum device votes: 1
[root@jrummy5-1 ~]# 

[root@jrummy5-2 ~]# cman_tool status | grep "Quorum device"
[root@jrummy5-2 ~]# 

Environment

  • Red Hat Enterprise Linux (RHEL) 5 with the High Availability Add On
  • A quorum device configured in master_wins mode (<quorumd master_wins="1">) in /etc/cluster/cluster.conf
