RHBA-2007:0861 - Bug Fix Advisory

Topic

Updated dlm-kernel packages that fix module loading issues and various bugs
are now available for Red Hat Enterprise Linux 4 Update 5, kernel release
2.6.9-55.0.6.EL.

Description

The dlm-kernel modules allow the Distributed Lock Manager (dlm) to
communicate with the kernel.

These updated dlm-kernel packages are in sync with the latest kernel
(2.6.9-55.0.6.EL). The modules in earlier dlm-kernel packages failed to
load because they did not match the running kernel. It was possible to
force load the modules. With this update, however, users no longer need to.

As well, the following issues have been addressed in this update:

• a bug was fixed which could cause a crash when /proc/cluster/dlm_locks

was viewed.

• a bug was fixed which caused dlm operations to block when a tcp

connection was initiated to the dlm port.

• a bug was fixed which caused cman to incorrectly report that clvmd

startup failed.

Users are advised to upgrade to these latest dlm-kernel packages, which are
updated for use with the 2.6.9-55.0.6.EL kernel.
