RHBA-2012:0353 - fence-agents bug fix update

Synopsis

fence-agents bug fix update

Type/Severity

Bug Fix Advisory

Topic

An updated fence-agents package that fixes one bug is now available for Red Hat Enterprise Linux 6.

Description

Red Hat fence agents are a collection of scripts to handle remote power management for several devices. They allow failed or unreachable nodes to be forcibly restarted and removed from the cluster.

This update fixes the following bug:

  • The fence_rhevm fencing agent uses the Red Hat Enterprise Virtualization API to check the power status ("on" or "off") of a virtual machine. In addition to the states of "up" and "down", the API includes other states like "unassigned", "powering_up", "paused", "migrating", "unknown", "not_responding", "wait_for_launch", "reboot_in_progress", "saving_state", "restoring_state", "suspended", "image_illegal", "image_locked" or "powering_down". Previously, only if the machine was in the "up" state, the "on" power status was returned. The "off" status was returned for all other states although the machine was actually running. This allowed for successful fencing even before the machine was really powered off. With this update, the fence_rhevm agent detects power status of a cluster node more conservatively, and the "off" status is returned only if the machine is really powered off, it means in the "off" state. (BZ#785816)

All users of fence-agents are advised to upgrade to this updated package, which fixes this bug.
