David, do you know if 4k disks over NFS works for sanlock?
When using files, sanlock always does 512 byte i/o. This can be a problem when there are 4k disks used under NFS. On disks, sanlock detects the sector size (with libblkid) and uses 512/4k accordingly. If vdsm knows when to use 4k i/o over files, I can add a sanlock flag that vdsm can use to create 4k sanlock leases. Dave
