No, nothing. Not for lvm, not for xfs.

Ah, silly me. Right, will try.

The problem is that xfs_repair does not at all complain, but when I 
mount it nothing is correct. I cannot even get those data which is at 
least displayed normally. xfs_repair doesn't find a problem - that's the 
problem.

All data should be there. As I understand it, partitioning a disk writes 
to the partition table (sector 0?), the partition created should have 
started at sector 63 or 2048, and the "mkswap" will have written only a 
very small amount too. I guess that a very bad block has been hit, but 
is really everything lost now?
