Thanks Eric. That was it. When I had taken the LVM back to it's
original size I inadvertantly subtracted too many extents. Once I made
the LVM the corrent number of extents, I was able to read the

Or is it possible to rebuild the superblock?
Are you sure your lvm volume is reassembled properly... after repair
finds the first superblock, it checks to be sure it looks fairly sane,
then compares it against a number of other superblocks, checking for
consistency. Here it looks like it's trying to check a superblock
that should be towards the end of the disk - looks like still a bit
under 2T - and it's failing because it can't seek out to that location
(not an xfs problem per se, this is a seek() system call that fails).
what does xfs_info on the filesystem say - I'd double check the
geometry /size it reports and compare it with the size of your volume....
