You have /var/lib/mfs/metadata.mfs on the master, it might not be corrupt 
after all?

I'd suggest:

- backup /var/lib/mfs to another disk/server (for later recovery if needed)
- make sure you have free space in your main disk
- then simply try to start mfsmaster
- check mfs.cgi (web interface) if it looks OK


BUT: if you can, wait for confirmation from Michał Borychowski first, in case 
what I'm telling you is not safe.


(BTW: You have Reply-To set to che...@cp..., I don't know if that's 
intentional on your part)

Hope it helps,
