When cluster nodes are started simultaneously rgmanager fails to start service with lvm resource in RHEL 6

Solution Unverified - Updated -


  • While testing for recovery after a power outage, both nodes are brought up at the same time. Rgmanager attempts to start both services on both nodes, and they fail.
  • LVM resources fail to start if another node is starting rgmanager at the same time:
Jul 05 13:23:46 rgmanager Failed to activate logical volume, myvg/mylv
Jul 05 13:23:46 rgmanager Attempting cleanup of vgsan01/mylv
Jul 05 13:23:47 rgmanager Failed second attempt to activate vgsan01/nfs00
Jul 05 13:23:47 rgmanager start on lvm "nfs-lvm" returned 1 (generic error)
Jul  5 13:23:46 node2 lvm[10266]: Error locking on node node1.example.com: Volume is busy on another node
  • I'm using HA-LVM with clvmd. I manually activated clustered volumes on one or more nodes in the cluster, and then those resources failed to start as part of their service on another node.


  • Red Hat Enterprise Linux (RHEL) 5 or 6 with the Resilient Storage Add On
  • Using HA-LVM with the clvmd variant
    • locking_type = 3 in /etc/lvm/lvm.conf
    • A service in /etc/cluster/cluster.conf containing an lvm resource
