RHBA-2014:1218 - Bug Fix Advisory

Topic

Updated lvm2 packages that fix two bugs and add one enhancement are now
available for Red Hat Enterprise Linux 5.

Description

The lvm2 packages provide support for Logical Volume Management (LVM).

This update fixes the following bugs:

• Prior to this update, the user had to specify major number together with minor

number when using persistent (-My/--persistent y) device numbers for logical
volumes (LVs). However, in kernel versions higher than 2.4, the "--major" option
is ignored because the kernel now assigns major numbers by itself. This behavior
cannot be overridden. Now, when specifying the persistent minor number with the
"lvcreate/lvchange -My/--persistent y --minor !" command, the user no longer
needs to specify the major number with the "--major" argument. If the "--major"
argument is used, the user is now informed by the following message:

"Ignoring supplied major number - kernel assigns major numbers dynamically.
Using major number <major number assigned by kernel> instead." (BZ#204997)

• Previously, if the pvmove command was executed on clustered volume groups,

temporarily activated pvmove devices were activated on all nodes. This was
incorrect and in some situations, such as using tags or HA-LVM configuration, it
caused pvmove failures. With this update, pvmove activates all needed pvmove
devices exclusively when moving logical volumes are already exclusively
activated. (BZ#1053849)

In addition, this update adds the following enhancement:

• Previously, the lvm-dumpconfig utility displayed the whole configuration but

without the logical volume (LVM) configuration tags set for the host. This
update introduces the "lvm tags" command which displays the configuration tags
set for the current host including the tag configuration which is used on the
host. (BZ#569511)

Users of lvm2 are advised to upgrade to these updated packages, which fix these
bugs and add this enhancement.
