RHBA-2014:1219 - lvm2-cluster bug fix update

Synopsis

lvm2-cluster bug fix update

Type/Severity

Bug Fix Advisory

Topic

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

Description

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

This update fixes the following bugs:

  • 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#966283)

  • 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#1005408)

  • 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. (BZ#1025881)

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

Solution

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