I have RAID5 volume that has two disk that have been marked as failed. 
I believe this happen do to loss of communication with the disk. NOT
because of a total disk failure. I assume if I can get the superblocks
back into a good state I can reassemble the RAID5 and try to read what
data I can off the volume. Does anyone know how to force RAID5
superblocks into a state so I can do reads from the volume? I really
need help on this. By the way the kernel version is 2.4.22.

mdadm has a --force option to the assemble command which I have used to
recover from a similar situation.  Don't forget to fsck the volume
afterwards, though, since it will have bad data on it.

logical to drop the ridiculous practice of referring to "God" as "he."
