That is what software raid is for. The devices are stackable, so you should have no problems. You should be able to do: harddrives|sofware RAID 0|LVM+striping harddrives|hardware RAID 0|LVM+striping harddrives|hardware RAID 0+1|LVM harddrives|LVM|sofware RAID 0+1 etc... > After using Sun's, and Veritas' volume managers under solaris, I > really would like to have something like this on my linux boxes.

That's a trick and a half if there was no LVM installed to begin with. You can convert an existing system completely to LVM, with the exception of /boot (unless you have a patched Lilo), if you have less than one half of the harddrive space occupied and you're willing to use parted. -- Chad Walstrom <chewie at wookimus.net> | a.k.a. ^chewie http://www.wookimus.net/ | s.k.a. gunnarr Get my public key, ICQ#, etc. $(mailx -s 'get info' chewie at wookimus.net) -------------- next part -------------- A non-text attachment was scrubbed...
