RHBA-2013:1471 - lvm2 bug fix update

Synopsis

lvm2 bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated lvm2 packages that fix several bugs are now available for Red Hat Enterprise Linux 6.

Description

The lvm2 packages include all of the support for handling read and write operations on physical volumes, creating volume groups from one or more physical volumes and creating one or more logical volumes in volume groups.

This update fixes the following bugs:

• Previously, on certain HP servers using Red Hat Enterprise Linux 6 with the xfs file system, a regression in the code caused the lvm2 utility to ignore the "optimal_io_size" parameter and use a 1MB offset start. Consequently, there was an increase in the disk write operations which caused data misalignment and considerably lowered the performance of the servers. With this update, lvm2 no longer ignores "optimal_io_size" and data misalignment no longer occurs in this scenario. (BZ#965810)

• The lvm2 tools determine the PowerPath major number by searching for an "emcpower" line in the /proc/devices file. Previously, some versions of PowerPath used the ID string "power2". Аs a consequence, on systems with such an identifier, PowerPath devices were not given the expected precedence over PowerPath components which exhibit the same physical volume UUID. With this update, detection of EMC power devices works as expected, and the priority of devices is now set properly (BZ#965968)

• Due to an error in the LVM allocation code, lvm2 attempted free space allocation contiguous to an existing striped space. When trying to extend a 3-way striped logical volume using the lvextend command, the lvm2 utility terminated unexpectedly with a segmentation fault. With this update, the behavior of LVM has been modified, and lvextend now completes the extension without a segmentation fault. (BZ#1016083)

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

Solution
