RAID5 failure; possible to repair?

[Ramon Hofer <ramonhofer@bluewin.ch>]

Hi all

I have a home server with a raid5.
After switching to a new case my graphics card died and I replaced it 
with an old but very powerful card just to try things.

Unfortunately the PSU wasn't strong enough and there were some crashes.

I could fix the problems of the other disks but I had no luck with the 
raid.

What I did is:

First I checked with `mdadm --detail /dev/md0` and everything seemed fine 
(raid clean).
But it wasn't possible to mount md0 so I ran `fsck /dev/md0` which was 
busy for quite a while. It removed one disk after the other from the 
raid. Afterwards I ended with an empty raid with four spare disks and now 
I don't even have a md0 device.

Is there anything I can do to recover the files from there or should I 
start from scratch?


Best regards
Ramon
