SUSE Recommended Update: Recommended update for cluster-glue and SBD
Announcement ID: SUSE-RU-2012:0839-1
Rating: low
References: #738295 #753559 #761797 #762300 #767293
Affected Products:
  • SUSE Linux Enterprise High Availability Extension 11 SP2

  • An update that has 5 recommended fixes can now be installed. It includes one version update.


    This update to the STONITH Block Device (SBD) adds support
    for taking the quorum state and Pacemaker health into
    account when the majority of SBD devices is unreachable.

    This allows clusters running SBD to survive transient
    faults in the storage layer as long as the cluster
    partition remains quorate and the node is in a healthy
    state. This new feature is activated using the "-P" flag
    in /etc/sysconfig/sbd; please see the sbd man page for
    further details.

    IO to the devices is now fully asynchronous, and enforces
    its own timeouts and retries. Previously, IO processes
    could get stuck on certain multipath issues, and SBD had
    to wait until the SCSI IO timed out. This allows SBD's
    watchdog and msgwait timeouts to be reduced and thus
    results in faster fail-overs in the cluster.

    The restart logic of IO processes has been improved and
    clarified in the man page.

    It is now possible to specify a different watchdog timeout
    for the crashdump support, so that crashdumps do not get
    interrupted by the watchdog triggering.

    Missing devices no longer fail the list or dump commands.

    sbd is now provided as a separate RPM from cluster-glue;
    both are automatically installed by this update.

    Please refer to the changelog for further details.
