The primary superblock is not good, and it's trying to find a valid
secondary superblock. Doesn't sound promising so far - reapir can't
start until a valid superblok is found....

Can you dump the first sector of the device the fielsystem is
on:

# dd if=/dev/mapper/vg0-hladata3 bs=512 count=1 iflag=direct 2> /dev/null | od -Ax -x

So we can see if that really holds a primary XFS superblock?

Cheers,

Dave.
