I could very well be recalling incorrectly, though. Is mdadm or raidtools being started on bootup? (Check your init scripts.) That should be able to figure out the array and get it going, even if the kernel autostart didn't. If you're using raidtools, you might want to switch to mdadm - it has the nifty ability to e-mail you when a drive goes belly-up. -- Nate Carlson <natecars at real-time.com> | Phone : (952)943-8700 http://www.real-time.com | Fax : (952)943-8500
