RHBA-2011:0236 - Bug Fix Advisory

Topic

An updated lvm2 package that fixes several bugs and adds an enhancement is now
available for Red Hat Enterprise Linux 4.

Description

The lvm2 packages provide support for Logical Volume Management.

This update fixes the following bugs:

• This update ensures that the pvcreate utility correctly detects and

conditionally wipes swap space signatures. (BZ#488354)

• This update enables the use of cached metadata for the pvs and pvdisplay

commands to avoid excessive memory consumption when processing Volume Group with
large number of Physical Volumes (PVs). (BZ#488739)

• Under certain circumstances, running the pvmove utility could cause a device

to be left in a suspended state. This update fixes the pvmove abort to be
cluster-aware when a temporary mirror activation fails. (BZ#500849)

• The manual page for the lvs utility has been corrected to provide more

detailed information about supported arguments of the "-o" command line option.
(BZ#500861)

• Previously, the vgreduce utility could terminate unexpectedly with a

segmentation fault when a device disappeared from the system. With this update,
a backported patch has been applied to address this issue, and the absence of a
device no longer causes vgreduce to crash. (BZ#531250)

• Due to an error in the device-mapper library, on certain configurations, the

vgchange utility could terminate unexpectedly with a segmentation fault when
calling a hash table lookup function. This occurred during the execution of the
lookup function when keys of different lengths were compared. With this update,
the package has been updated to use the corrected device-mapper library, and
hash table lookups no longer cause a segmentation fault. (BZ#571699)

As well, this update adds the following enhancement:

• The pvmove utility has been updated to produce a more descriptive error

message when when all source logical volumes (LVs) are skipped. (BZ#500898)

Users of lvm2 are advised to upgrade to this updated package, which resolves
these issues and adds this enhancement. In clustered environments, this bug fix
must be applied along with the lvm2-cluster advisory.

Solution

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

This update is available via Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
