3.45. lvm2-cluster

Updated lvm2-cluster packages that fix several bugs are now available for Red Hat Enterprise Linux 5.

The lvm2-cluster packages contain support for Logical Volume Management (LVM) in a clustered environment.

Bug Fixes

BZ#966283: Incorrect validation of the clvmd daemon request could lead to a failure with numerous error messages logged. This bug also caused considerable CPU consumption, locking up all logical volume (LVM) commands due to false interpretation of the requests and exhaustive logging. A set of patches has been provided to improve the clvmd request validation, thus fixing the aforementioned bug.
BZ#1005408: When one of the logical volume (LVM) client processes was killed, the clvmd daemon had to wait for a mutual exclusion (mutex) to stop the LVM client thread. Consequently, lvm utility commands in a cluster became indefinitely blocked. This update introduces a patch which fixes the deadlock, and lvm utility commands now work correctly.
BZ#1025881: Due to a regression, the "clvmd -R" command failed to execute with the following error message:
"EOF reading CLVMD"
The underlying source code has been fixed, and "clvmd -R" now works as intended.

Users of lvm2-cluster are advised to upgrade to these updated packages, which fix these bugs.
