Name        : lvm2
Product     : Fedora 21
Version     : 2.02.115
Release     : 2.fc21
URL         : http://sources.redhat.com/lvm2
Summary     : Userland logical volume management tools
Description :
LVM2 includes all of the support for handling read/write operations on
physical volumes (hard disks, RAID-Systems, magneto optical, etc.,
multiple devices (MD), see mdadd(8) or even loop devices, see
losetup(8)), creating volume groups (kind of virtual disks) from one
or more physical volumes and creating one or more logical volumes
(kind of logical partitions) in volume groups.

--------------------------------------------------------------------------------
Update Information:

This update provides an urgent fix for a bug where newer versions of LVM2 tools do not
recognize cache mode in case cache LVs were created by older LVM2 tools where cache mode
was not specified directly in metadata. Also, this update fixes configuration for cache
tools (cache_check, cache_dump, cache_repair) so they're properly configured for use
with LVM2 tools.
