No because I've already "been there" and "done that" -- It is IMPOSSIBLE to recover a RAID-1 array that just one day (after properly shutting down the system and not having hardware failures) decided not to boot.
Ahhh, now this is interesting :) The main reason I was creating the RAID1 array was so that if one drive failed, I could receive a message from mdadm, swop out the bad drive and continue working, without losing data.
In view of the above comment, I guess it is time I ordered the 3rd HDD and rather setup RAID5.
No Hylton. Andrew just had one bad experience. You can use Soft RAID1 with no problem. I use both RAID1 and RAID5 on several machines and, if a drive "dies", I get a message from mdadm stating it. I can also change the faulty HD with no downtime at all ( depending on your hardware ). IMO, you should take Andrew's experience as Linux Software RAID is not perfect. Well... nothing is... but IMO, it is very close to it :)

Maybe the issue is not mdadm but instead openSUSE 11.0? Either way I'd advise to stay away from md RAID and its horrible mdadm tool. For me I prefer to switch to hardware RAID cards and keep on using openSUSE.
HW RAID cards are a MAJOR expense for a home hobbyist who just likes to make sure their data is retrievablein the event of a HDD crash.
