RHBA-2007:0861 - dlm-kernel bug fix update

Synopsis

dlm-kernel bug fix update

Type/Severity

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.

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.
