LVM volume cannot be activated via rgmanager using clvmd on Red Hat High Availability

Solution Verified - Updated -


  • We are unable to start few services on our cluser node. we are getting error while trying to start the service.
$ /usr/sbin/clusvcadm -e service:rd1svc
Local machine trying to enable service:rd1svc...Aborted; service failed 
  • When checked mount point and respective devices, we found auto LVM getting inactive.


  • Red Hat Enterprise Linux (RHEL) including:

    • Red Hat Enterprise Linux Server 5 (with the High Availability Add on)
  • Red Hat High Availability Cluster with 2 or more nodes
  • Clustered LVM (clvm) managing shared storage
  • rgmanager managing service groups

    • Service contains an LVM resource (HA-LVM - CLVM variant), and that service has a failover domain specified (domain="rd1" for example):
        <fs device="/dev/mapper/vg_data-rd1_vol" force_fsck="1" force_unmount="1" fstype="ext3" mountpoint="/app/rd1" name="rd1fs" self_fence="0"/>
    <lvm lv_name="rd2_vol" name="rd2lvm" vg_name="vg_data"/>
      <service autostart="0" domain="rd1" exclusive="0" name="rd1svc" recovery="disable">
    <lvm ref="rd1lvm"/>
    <fs ref="rd1fs"/>
    • Service is not allowed to start on all cluster nodes. For example, the service above is part of this failover domain, and is only allowed to start on 2 of the 3 nodes (not allowed to start on node5). The failover domain is also restricted="1":
        <failoverdomain name="rd1" nofailback="1" ordered="1" restricted="1">
          <failoverdomainnode name="node4" priority="1"/>
          <failoverdomainnode name="node5" priority="1"/>
    • The LVM logical volume is (a)ctive on the 1 cluster node that the service is not allowed to run on:
    # hostname
    # lvs
      LV               VG      Attr   LSize   Origin Snap%  Move Log Copy%  Convert
      rd1_vol         vg_data -wi-a-   6.00G
