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.
