Neither is very good. If half your file systems "goes away" you'll probably end up losing more than half your data. LVM will, by default, not do striping and a non-stripped loss seems more likely to be recovered by an fsck. Software RAID (md) also seems to have a non-striped mode with should work just as well. I think the LVM approach is a little more flexible, but the md approach could perform a little better. Buy another 500GB disk and do software RAID 5 if you really need 1TB of space. It won't be great, but it'll be a LOT safer than what you are proposing. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
