   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.
