So I was trying to copy over some Indiana Jones wav files and it
wasn't going my way. I noticed that my software raid device showed:
/dev/md1 on / type ext3 (rw,errors=remount-ro)
Is this saying that it was remounted, read only because it found a
problem with the md1 meta device? That's what it looks like it's
saying but I can still write to /.
mdadm --detail showed:

I have two 1 terabyte sata drives in this box. From what I was
reading wouldn't it show an F for the failed drive? I thought I would
see that /dev/sdb1 and /dev/sdb2 were failed and it would show an F.
What is this saying and how do you know that its /dev/sdb and not some
other drive? It shows removed and that the state is clean, degraded.
Is that something you can recover from with out returning this disk
and putting in a new one to add to the raid1 array?
Thanks,
Jonathan
