RHBA-2007:0137 - Bug Fix Advisory
Synopsis
dlm-kernel bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated dlm-kernel packages that fix several bugs are now available.
Description
The dlm-kernel modules allow the dlm (distributed lock manager) to
communicate with the kernel.
Bugs fixed in these updated packages include:
- when callng the dlm_ls_unlock_wait function with the LKF_CANCEL flag, a
kernel panic could occur.
- when dlm_unlock was called on a lock that was already unlocked, a kernel
panic could occur.
These updated dlm-kernel packages are in sync with the latest kernel:
2.6.9-55.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; however, with this update, users no longer need to.
Users are advised to upgrade to these latest dlm-kernel packages, which are
updated for use with the 2.6.9-55.EL kernel.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
