RHEA-2012:0996 - Product Enhancement Advisory

Topic

Updated sanlock packages that add multiple enhancements are now available for
Red Hat Enterprise Linux 6.

Description

The sanlock packages provide a shared disk lock manager that uses disk paxos to
manage leases on shared storage. Hosts connected to a common Storage Area
Network (SAN) can use sanlock to synchronize the access to the shared disks.
Both libvirt and vdsm can use sanlock to synchronize access to shared virtual
machine (VM) images.

The sanlock packages have been upgraded to the latest upstream version, which
provides a number of enhancements over the previous version. (BZ#782600)

All users of sanlock are advised to upgrade to these updated packages, which add
these enhancements.
