[libvirt-users] Sanlock - what are my options?

Hi all, I have an RHCS 2 node cluster utilizing SAN storage with GFS2 for the VM images. I am looking into configuring Sanlock, however am running into some architecture questions with it. The documentation for Sanlock states: "The sanlock plugin needs to create leases in a directory that is on a filesystem shared between all hosts running virtual machines. Obvious choices for this include NFS or GFS2." I do not have a highly available NFS mount where I can store the disk leases, and I cannot store the lockspace on the same GFS2 mount as the disk images as during fencing/journal recovery disk I/O can become blocked, which causes Sanlock to log warnings/errors about renewals. Is there another option for configuration?
