You can (sort of) run raid on an entire disk, but you have to use LVM. You basically create a single partition on the disk, run raid on that partition and then use LVM with the /dev/md? device as a physical volume that you can then "partition" with LVM. -Dave _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
