1.90.2. RHBA-2011:0287: lvm2 bug fix update

An updated lvm2 package that resolves several issues is now available.
The lvm2 package contains support for Logical Volume Management (LVM).
This updated lvm2 package provides fixes for the following bugs:
* With this update, the "File-based locking initialization failed." warning, which was displayed during the system start-up, is now suppressed. (BZ#673975)
* 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 This could result in the use of outdated metadata values.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#673981)
* This update fixes a faulty initialization which in certain cases lead to a full unconditional rescan of devices. As a result, all lvm operations were slowed down and exhibited poor performance. (BZ#673986)
All users of lvm2 are advised to upgrade to this updated package, which resolves these issues.
