          The simplest way to clear up the file system on a SAN disk is to work with the SAN admin and have him disconnect the SAN disk from the server, unbind then rebind the SAN disk, making sure it has the same size. Once the SAN disk is rebound, he should then reattach the disk to the server.

          After rebooting the server, the SAN disk will present itself as an unformatted disk. On OVM3 manager, it will appear to be a different disk since the UUID will change.

          All of these will take a max of 15 to 20 minutes of the SAN admin's time plus the time for reboot.

          I find this method to be more effective than blanking out every block on the SAN disk.
