RAID5 temperorary loss two disk

   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.

    Thank You

Unfortunately very little effort seems to be spent on documenting the

features of device-mapper and how to use them. I originally intended to use
DM, but since i could not find any information on how to configure mirrored
multipath devices i decided against it.

What is the word on MD and DM? I miss some sort of road map and a general

overview (preferrably with executive summary). (I am willing to write one if
i can find/get the necessary information.)

I'm quite fond of my docs on multipath with the device-mapper subsystem.
You can find them at http://christophe.varoqui.free.fr

Hope it helps.
