RHBA-2017:0992 - lvm2 bug fix update

Synopsis

lvm2 bug fix update

Type/Severity

Bug Fix Advisory None

Topic

Updated lvm2 packages that fix one bug are now available for Red Hat Enterprise Linux 7.

Description

The lvm2 packages include complete 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 bug:

• When the clvmd service used the cpg_mcast_joined() call, corruption of the inter-process communication (IPC) ring buffer in some cases occurred. As a consequence, the Corosync engine entered an endless loop, and sometimes caused unavailability of services on a server node managed by Corosync. This update implements a mutual exclusion algorithm to protect cpg_mcast_joined(), which prevents the described problem. (BZ#1436311)

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

Solution

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