RHBA-2008:0378 - Bug Fix Advisory

Topic

An updated lvm2 package that fixes several bugs and adds enhancements is
now available.

Description

The lvm2 package contains support for Logical Volume Management (LVM).

This updated package fixes the following bugs:

• changes "vgsplit -l", for the unimplemented "--list" option, into

"--maxlogicalvolumes".

• fixes the detection of PVs that have no metadata.
• prevents overwriting PVs with no metadata areas belonging to active VGs.
• fixes the "lvcreate --addtag" option to drop the "@" prefix from the

name.

• prevents the "lvconvert -s" command from using same LV as the origin and

the snapshot.

• fixes the human-readable output for odd numbers of sectors.
• fixes missing VG unlocks in some "pvchange" error paths.
• ignores and fixes any excessive device sizes found in metadata.
• fixes error messages when fixing PV sizes in LVM2 metadata.
• detects command line PE values that exceed their 32-bit range.
• fixes snapshot copy on write (COW) area deactivation if the origin is not

active.

• prints "--help" to standard output, instead of standard error output. As

well, after a command line processing error, help text is not longer
printed, but rather the "--help" option is suggested.

• prints warnings to standard error output, instead of standard output.
• updates to man pages, including the "--uuid" argument, and the

"lvdisplay" command.

• more information about clusters has been added to the output of

"lvmdump".

• kernel and Device-mapper target versions have been added to "lvmdump".
• fixes the "pvs -a" command, so that it detect VGs of PVs without metadata

areas.

As well, this updated package adds the following enhancements:

• adds metadata area, segment, and convert fields to reporting commands.
• updates "vgsplit" to accept an existing VG as a destination.
• adds a preview of the snapshot monitoring library. Refer to the

lvm.conf(5) man page for details.

• adds sizes with the "lvcreate --readahead" command.
• adds support for the full read-ahead setting.
• sets the default read-ahead value to twice the maximum stripe size.
• adds LVM2 version to the "Generated by" comments in metadata.
• detects MD superblocks versions 1.0, 1.1 and 1.2.
• adds the "%PVS" extents option to the "lvresize", "lvextend", and

"lvcreate" commands.

• adds support for renaming mirrored LVs.
• adds the "--mirrorlog" argument to specify a log type for mirrors.
• adds Sun Microsystems LDom virtual block device (vdisk) and ps3disk to

filters.

• the "vgsplit" command now handles an entire VG as a "vgrename".
• a warning is now displayed when running LVM2 commands as a non-root

user.

• adds a "vgremove -f" option, to forcefully remove a VG, even when LVs

still exist.

In clustered environments, this fix must be applied along with the
RHBA-2008:0084 lvm2-cluster advisory.

Users of lvm2 are advised to upgrade to this updated package, which
resolves these issues and adds these enhancements.
