3.4 6.1. RHBA-2014 :1218 — lvm2 bug fix and enhancement updat e
Updated lvm2 packages that fix two bugs and add one enhancement are now available for Red Hat
Enterprise Linux 5.
The lvm2 packages provide support for Logical Volume Management (LVM).
B u g Fixes
B Z #204 9 9 7
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."
B Z #105384 9
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.
In addition, this update adds the following

B Z #56 9 511
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.
Users of lvm2 are advised to upgrade to these updated packages, which fix these bugs and add this
enhancement.
3.4 7. microcode_ct l
3.4 7.1. RHEA-2014 :1236 — microcode_ct l enhancement updat e
Updated microcode_ctl packages that add one enhancement are now available for Red Hat
Enterprise Linux 5.
The microcode_ctl packages provide utility code and microcode data to assist the kernel in updating
the CPU microcode at system boot time. This microcode supports all current x86-based, Intel 64based, and AMD 64-based CPU models. It takes advantage of the mechanism built-in to Linux that
allows microcode to be updated after system boot. When loaded, the updated microcode corrects the
