RHBA-2010:0432 - Bug Fix Advisory

Topic

Updated lvm2-cluster packages that fix various bugs are now available.

Description

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

This update ensures that the bugs fixed by the lvm2 advisory are also fixed in a
clustered environment, namely these bugs:

• avoids repeated full device scans if using internally-cached VG metadata

(which happens on systems with a missing device in a Volume Group). (BZ#584705)

• fixes unexpected symbolic link removal if device is still active after

deactivation failure. (BZ#580831)

This update also applies the following clustered lvm only bug fixes:

• fixes thread race which can happen if clvmd is under high load and leads to

clvmd hangs. (BZ#584706)

• fixes clvmd init script info to properly shutdown Logical Volumes if GFS is

used on them. (BZ#591524)

• fixes vgscan to refresh device cache if cluster locking is used and device

filter in lvm.conf is changed. (BZ#592220)

Users of lvm2-cluster are advised to upgrade to these updated packages, which
resolve these issues.
