Hi,

i've got a raid1 setup, where one drive died, it was replaced with a new
one, but its stuck in a (S) state and I can't seem to get it added into
the array, /proc/mdstat looks like this:

md3 : active raid1 sdc1[2](S) sdd1[1]
      976759672 blocks super 1.2 [2/1] [_U]

where sdc1 is the replaced drive.

Hi Micah,

What does the output from mdadm --detail /dev/md3 look like?
