rgmanager bug fix and enhancement update

Updated rgmanager packages that fix various bugs and add enhancements are
now available.

The rgmanager package contains the Red Hat Resource Group Manager, which
provides high availability of critical server applications in the event of
planned or unplanned system downtime.

These updated packages address the following issues:

* running the "clustat" command when qdisk has been configured caused the
status of nodes to be reported incorrectly. Interaction between rgmanager
and qdisk has been resolved in this update.

* if the node processing a request from clusvcadm crashed, clusvcadm would
hang. This has been resolved in these updated packages.

* using rg_test to stop, start then stop a cluster service with an IP
address and no netmask specifically defined, caused the following warning
"Warning: Executing wildcard deletion to stay compatible with old scripts.
Explicitly specify the prefix length (<ip-address/prefix>) to avoid this
warning. This special behavior is likely to disappear in further releases,
fix your scripts!". This was due to a change in how iproute2 parses
parameters. These updated packages resolve this issue.

* a fail-restart loop occurred instead of failover when a link was
unplugged. In these updated packages ip.sh fails during the start phase
if a link is unplugged.

* previously rgmanager could stop resources in the wrong order. Implicit
ordering guarantees are now provided in cluster.conf, resolving this issue.

* rgmanager live migration for VMs is now enabled and functional.

* nodes were able to run multiple resources marked as "exclusive" which
could lead to data corruption. These updated packages change this
behavior, allowing only one service to run as "exclusive".

* subtrees can now be restarted without restarting the service.

* previously resource agents were not probing according to configured time
intervals. This behavior has been resolved in this update.

* restarting rgmanager no longer restarts the node erroneously.

* the rgmanager init script now provides correct exit codes.

* rgmanager now correctly mounts the Veritas File System (VxFS).

* previously stopping the rgmanager service on a node caused rgmanager to
exit uncleanly without stopping the Distributed Lock Manager (DLM)
service. This prevented the Cluster Manager (CMAN) service stopping on the
last node. Rgmanager's DLM lock space is no longer left open if the CMAN
service is stopped first, resolving this issue.

* rgmanager now prevents more than one status check from being queued,
preventing long status checks repeatedly being queued.

* rgmanager no longer restarts virtual machines when adding them as a
Cluster Managed service.

* rgmanager no longer causes a node to restart if it is shutdown while
processing a relocation request.

* a memory leak occurring during the simultaneous relocation of multiple
services has been fixed.

This update also adds the following enhancements:

* there is now a clusvcadm flag to respect failover domain priorities
when enabling services.

* rgmanager now detects virtual machine migration if non-cluster tools are
allowed.

* nested resources can now inherit attributes from all direct ancestors,
not just direct parents.

All rgmanager users should upgrade to these latest packages, which
resolve these issues and add these enhancements.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
