Norman,
I am extremely interested in what distribution you are running on it and
what type of SW raid you are employing (besides the one you showed here),
are all 48 drives filled, or?

Justin,
This is a Sun X4500 (Thumper) box, so it's got 48 drives inside.
/dev/sd[a-z] are all there as well, just in other RAID sets. Once you
get to /dev/sdz, it starts up at /dev/sdaa, sdab, etc.
I'd be curious if what I'm experiencing is a bug. What should I try to
restore the array?

Neil,
Is this a bug?
Also, I have a question for Norman-- how come your drives are sda[a-z]1?
Typically it is /dev/sda1 /dev/sdb1 etc?
Justin.

But why do two show up as "removed"?? I would expect /dev/sdal1 to show up
someplace, either active or failed.
Any ideas?
Thanks,
Norman

So I had my first "failure" today, when I got a report that one drive
(/dev/sdam) failed. I've attached the output of "mdadm --detail". It
appears that two drives are listed as "removed", but the array is
still functioning. What does this mean? How many drives actually
failed?
This is all a test system, so I can dink around as much as necessary.
Thanks for any advice!
