Hmm, yes, thats a bit too large.

These all look pretty wierd... I'd start with reseting all these to
sane default values, then run repair again.  I created a file like
yours, and repair was OK with it, so possibly there'll be some other
issues - send me the repair output if it still fails after resetting.
So, the db commands would be something like:

# xfs_db -x /dev/mdXXX
xfs_db> inode 134762498
xfs_db> write core.format 2
xfs_db> write core.size 0
xfs_db> write core.dmevmask 0
xfs_db> write core.dmstate 0
xfs_db> quit

then run xfs_repair again and see how that goes.

cheers.
