RHBA-2013:0419 - Bug Fix Advisory

Topic

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

Description

The fence-virt packages provide a fencing agent for virtual machines as well as
a host agent, which processes fencing requests.

This update fixes the following bugs:

• Previously, the fence_virt man page contained incorrect information in the

"SERIAL/VMCHANNEL PARAMETERS" section. With this update, the man page has been
corrected. (BZ#761228)

• Previously, the fence_virtd daemon returned an incorrect error code to the

fence_virt agent when the virt domain did not exist. Consequently, the
fence_node utility occasionally failed to detect fencing. With this update, the
error codes have been changed and the described error no longer occurs.
(BZ#853927)

This update also adds the following enhancements:

• The "delay" (-w) option has been added to the fence_virt and fence_xvm fencing

agents. The delay option can be used, for example, as a method of preloading a
winner in a fence race in a CMAN cluster. (BZ#823542)

• With this update, the documentation of the "hash" parameter in the

fence_virt.conf file has been improved to notify that hash is the weakest
hashing algorithm allowed for client requests. (BZ#843104)

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