A new sanlock package is now available for Red Hat Enterprise Linux 6.
The sanlock package provides 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.
This enhancement update adds the sanlock package to Red Hat Enterprise Linux 6. (BZ#658971
All users who require sanlock are advised to install this new package.
