Well, the main reason I use MD for all my personal RAID needs is becuse I trust it more than any other RAID solution I have ever come across. Even in the event of a disaster, I know my data is there and I know I have the ability to get it back. I use LVM when I need to do volume management for the same reason. I know it, I trust it, I like it. It sounds like you have a setup that works well and accomplishes your goals.

Unless you want to LVM your / too, you can get away without initrd by using the kernel command-line to assemble your md devices. If you've never seen it, check Documentation/md.txt for syntax and details. Debian's mkinitrd scripts do a pretty good job of building initrd's for md, though I can't vouch for their LVM support. My workstation runs Slackware, and I'm far too lazy to build my own initrds ::-). -- Ross Vandegrift ross@xxxxxxxxxxxx "The good Christian should beware of mathematicians, and all those who make empty prophecies.
