No ARRAY statements at > all. What did I do wrong? Not sure if you did anything wrong, but now that you've done the --create operation, you might try running # mdadm --detail --scan again. You might see that it now outputs definition lines like the ones Dan presented as examples; if so, you can append those lines to mdadm.conf, and if I'm not mistaken the result should (in theory) be valid. > And again, I don't trust UUID's as moving a drive cable to a > different socket has invalidated the whole lot of them once before. Eh? That doesn't make any sense at all. The UUID is supposed to be stored *on* the drive, so that it is independent of connection. I can testify that this has been the case in my experience with mdadm RAID-array UUIDs. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
