RHBA-2011:0134 - Bug Fix Advisory

Topic

Updated rgmanager packages that provide a fix for a bug and add an enhancement
are now available for Red Hat Enterprise Linux 5.

Description

The rgmanager packages contain the Red Hat Resource Group Manager, which
provides the ability to create and manage high-availability server applications
in the event of system downtime.

This update addresses the following bugs:

• HA-LVM now resolves volume group names correctly (BZ#506587)
• HA-LVM can now protect from metadata changes by utilizing CLVM; logging has

also been improved (BZ#509368 BZ#572311 BZ#583769 BZ#585229)

• The NetBIOS name stored in the automatically generated smb.conf files for

services now has spaces removed (BZ#531098)

• It is now possible to stop rgmanager before CMAN finishes starting (BZ#545229)
• Failover domains are now documented in the rgmanager.8 man page (BZ#557562)
• SAPInstance and SAPDatabase resource agents no longer leave extraneous

temporary files (BZ#565363)

• Rgmanager now retries the operation if it tries to relocate a service to

another node before that node has reread the cluster configuration file
(BZ#568126)

• fs.sh no longer sleeps unnecessarily if the file system is already unmounted

during a stop operation (BZ#573705)

• Postgres-8 agent will now stop correctly if there are active clients connected

(BZ#587735)

• Restricted failover domain boundaries are now honored when performing virtual

machine migrations (BZ#592380)

• Temporary files created when using NFS lock code are now deleted (BZ#595455)
• Live migrations now use the correct interfaces when using migration mappings

(BZ#596016)

• Errors from tomcat.sh have been addressed (BZ#591003)
• Previously, clusters failed to recover from a clurgmgrd crash if the reboot()

system call failed. With this update, the rgmanager watchdog process now uses a
more robust method to reboot the machine if the main rgmanager process crashes.
(BZ#608397)

• clustat no longer returns 255 if rgmanager is not running (BZ#620730)
• If openais dies, rgmanager now halts services and exits (BZ#639961)
• Handling of CIFS mount points mounted from the netfs agents has been improved

(BZ#640676)

• User-specified migration URIs work correctly with the fix for BZ#569016

(BZ#659477)

• The postgres-8 resource agent now correctly places IP netmask information into

the configuration files it generates (BZ#614456)

This update also contains the following enhancements:

• Previously, vm.sh only checked the status of the VM itself, not the status of

any services inside. With this update, administrators may now use a newly
provided status check program which checks the availability of services within
virtual machines running Red Hat Enterprise Virtualization Manager. Timeouts for
starting and stopping virtual machines are now configurable in cluster.conf. The
start timeout is based on the status check program. (BZ#583788)

• Independent subtrees may now be flagged as 'non-critical', meaning they may

fail and have their components manually restarted without the entire service
being affected (BZ#605733)

• The file system agent will now accept 'vxfs' as the file system type

(BZ#531843)

• The file system agent will now accept 'ext4' as the file system type

(BZ#636550)

• Users of Oracle database may now separate the listener from the database

instance and have multiples of each resource type in a single cluster. This
feature is offered as a Technical Preview and is not supported in production
environments. (BZ#629208)

All users of Red Hat Resource Group Manager are advised to upgrade to these
updated packages, which address these issues and add these enhancements.
