RHBA-2013:0286 - fence-agents bug fix and enhancement update

Synopsis

fence-agents bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated fence-agents packages that fix multiple bugs and add four enhancements are now available for Red Hat Enterprise Linux 6.

Description

The fence-agents packages provide the Red Hat fence agents to handle remote power management for cluster devices. The fence-agents allow failed or unreachable nodes to be forcibly restarted and removed from the cluster.

This update fixes the following bugs:

• The speed of fencing is critical because otherwise, broken nodes have more time to corrupt data. Prior to this update, the operation of the fence_vmware_soap fence agent was slower than expected when used on the VMWare vSphere platform with hundreds of virtual machines. With this update, the fencing process is faster and does not terminate if virtual machines without an UID are encountered. (BZ#769798)

• Prior to this update, the attribute "unique" in XML metadata was set to TRUE (1) by default. This update modifies the underlying code to use FALSE (0) as the default value because fence agents do not use these attributes. (BZ#822507)

• Prior to this update, certain fence agents did not generate correct metadata output. As a result, it was not possible to use the metadata for automatic generation of manual pages and user interfaces. With this update, all fence agents generate their metadata as expected. (BZ#825667)

• Prior to this update, the fence_apc script failed to log into APC power switches where firmware changed the end-of-line marker from CR-LF to LF. This update modifies the script to log into a fence device as expected. (BZ#842314)

• Prior to this update, the fence_rhevm agent failed to run the regular expression get_id regex when using a new href attribute. As a consequence, the plug status was not available. This update modifies the underlying code to show the correct status either as ON or OFF. (BZ#863568)

This update also adds the following enhancements:

• This update adds the fence_ipdu agent to support IBM iPDU fence devices in Red Hat Enterprise Linux 6. (BZ#740869)

• This update adds the fence_eaton agent to support Eaton ePDU (Enclosure Power Distribution Unit) devices in Red Hat Enterprise Linux 6. (BZ#752449)

• This update adds symlinks for common fence types that utilize standards-based agents in Red Hat Enterprise Linux 6. (BZ#800650)

• This update adds the fence_bladecenter agent to the fence-agents packages in Red Hat Enterprise Linux 6 to support the --missing-as-off feature for the HP BladeSystem to handle missing nodes as switched off nodes so that fencing can end successfully even if a blade is missing. (BZ#818337)

• This update supports action=metadata via standard input for all fence agents. (BZ#837174)

All users of fence-agents are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
