RHBA-2011:0986 - Bug Fix Advisory

Topic

An updated lvm2-cluster package that fixes several bugs and adds various
enhancements is now available for Red Hat Enterprise Linux 5.

Description

The lvm2-cluster packages contain support for Logical Volume Management (LVM) in
a clustered environment.

This updated lvm2-cluster package ensures that the fixes provided with the Red
Hat Enterprise Linux lvm2 advisory are also fixed in a clustered environment.
The full list of changes is detailed in the WHATS_NEW file located in the
/usr/share/doc/lvm2-[version]/ directory.

This package also provides fixes for the following bugs:

• Wrongly-paired unlocking in the pvchange command has been fixed. (BZ#667517)
• O_DIRECT is now always used when block devices are opened to check for

partitioning. (BZ#673615)

• The clvmd daemon now respects the settings in the lvm.conf configuration file

when it initializes syslog.

• The exclusive lock now remains unchanged when a device is suspended by the

clvmd daemon.

• The clvmd daemon now properly increments the DLM lockspace reference count.
• The clvmd daemon now creates the /var/run/lvm/ directory during initialization

if it is missing.

In addition, this updated package provides the following enhancements:

• Activating snapshots of clustered logical volumes is now supported.

(BZ#501437)

• The clvmd daemon now supports the "--help" option, and returns proper exit

status codes upon exit. (BZ#666991)

• The clvmd daemon now supports the "-f" option, which prevents it from forking,

and the description for the "clvmd -d[number]" command has been improved.

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