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.
