Sometimes the softraid sets get put back but not in order. This bug has apparently been fixed in 4.6 but I haven't tried yet. I got stuck with a machine I couldn't reboot because I'd stored data on a RAID 0+1 (or was it the other way? I'm hopeless with the numbers) that I'd made using softraid. Thankfully I discovered the problem in a VM or I would have had to download all those eps of Hak.5 all over again... -- Aaron Mason - Programmer, open source addict I've taken my software vows - for beta or for worse
