ugh, that looks nasty - inode 448 seems to be a recuring theme.
can you send me output from:
# xfs_db -r -c 'inode 448' -c p /dev/XXX

[at a guess I'd say 448 is a directory inode, something in repair
thinks its free, and some other part of repair doesn't, and all the
other inodes are direct children of 448]

it would also help greatly if I could get access to the filesystem,
eg. by ssh or by downloading the compressed image (probably way too
big in your case by the look of it).

cheers.
