1.91.2. RHBA-2011:0288: lvm2-cluster bug fix update

An updated lvm2-cluster package that fixes a bug is now available.
The lvm2-cluster package contains support for Logical Volume Management (LVM) in a clustered environment.
This update ensures that bugs fixed by the lvm2 bug fix update advisory are also fixed in a clustered environment, namely the following bug:
* Under certain circumstances, mainly on shared storage systems, the buffered read of a device was used instead of a direct device access. This could result in the use of outdated metadata values. This update ensures that all device scan operations use the direct device access. (BZ#673980)
All users of lvm2-cluster are advised to upgrade to this updated package, which resolves this issue.
