David pointed out that if you run lvm without RAID, you actually increase the risk of losing data, since if any one drive fails, you probably lose everything (or at least have to do some hard recovery work).
Because of this, I've sometimes wondered if myth should allow multiple directories to be used for storing recordings. You make one partition on each drive you have, and tell myth the list of partitions. When starting a recording it chooses one of the directories. If one of the directories goes away, you just lose those recordings, but can keep on using the rest in the meantime. (And the database could be on a raid-5 filesystem so it survives no matter which drive fails.) I personally use raid-5 even for my recordings, since disks are cheap and time is expensive, so I don't need the above feature, but I'm throwing it out in case anyone else likes the idea. Dan
