Question mdadm says drives can't be found but I can find them...


Had a kernel panic on my screen when I woke up.

2 of my 4 mdadm arrays won't start. I can blkid the drives and find them, smartctl says everything is ok on all the drives of the array.

running mdadm --details /dev/md0 shows the configure and I can see the drives listed but the array is inactive and the drives all show up with -- under the number and raid device columns.

I'm not sure where to go from here.

Managed to get one array going with some playing. Was able to run mdadm -A /dev/md0 /dev/sda /dev/sdd /dev/sdf
which got the array going... then mdadm --add /dev/md0 /dev/sdg. Then it was immediately clean. I think some how my array' states got screwed up.

The last array is a bigger problem states with mdadm -E show

AA--
AAAA
A-AA
A-AA

So no matter what I try it shows max 2 drives as ok. Any way to clear those states to make it think all the drives are OK? (as one drive thinks)
