I guess I'm a weird one that never bothers to do Raid or LVM with my mythtv server. I might do RAID-1 sometime. Myth itself eliminates the need to do any LVM, really as it can easily handle multiple disks of various sizes. Of course you don't get the speed increase from striping, but I don't need that. If my myth disks get full or need replacing, I just rsync the contents to a new disk, then mount the new disk into the same location as the old disk and Myth just happily accommodates the increased space. -------------------- BYU Unix Users Group http://uug.byu.edu/ The opinions expressed in this message are the responsibility of their author.
