http://rhn.redhat.com/errata/RHBA-2014-0138.html

Root Cause

fs-snapshot plugin did not work with the Device Mapper because the "dmsetup splitname" command line interface had changed and it no longer supported the "-o" option. Consequently, the fs-snapshot plugin did not work. Firstly, fs-snapshot did not take snapshots of user's filesystems before running a yum transaction. Secondly, fs-snapshot did not work with LVM (Logical Volumes), creating no new LVM snapshots.
