lvm2-cluster bug-fix and enhancement update

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

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

This update ensures that the bugs fixed by the lvm2 advisory RHBA-2009:8160
are also fixed in a clustered environment.

This updated package applies the following bug fixes:

* Several bugs in the clvmd daemon that could cause the daemon to hang or
crash, have been resolved.
* Fixes uninitialized mutex in clvmd if all daemons are not running at
start up.
* Make clvmd refresh its internal state correctly when "lvm.conf" is updated.
* Make clvmd return at once if other nodes down in a gulm or openais cluster.

Also, this updated package adds the following enhancements:

* More detailed error messages. Many unnecessary error messages are now
suppressed.
* Updated man page and mention of the default "--clustered" setting in the
vgcreate man page.
* pvmove is now supported in a clustered VG if clustered mirroring support
is installed (kmod-cmirror).
* Indicate whether or not a VG is clustered in vgcreate log messages.
* clvmd now maintains local backups of VG metadata on each node.
* Decodes numbers in clvmd debugging output.
* Doesn't call openlog for every debug line output by clvmd.

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

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