Logs? Kernel version? etc.

To be clear, you've deleted partitions other than the partition of
interest? I suppose that shouldn't effect things either way, but I'm not
really sure what the disk utility might do. It might be worth checking
whether 'file -s <device>' still identifies the partition as an XFS
filesystem..?

Beyond that, I'd suggest to capture and post the logs of the failed
mount and perhaps the output of 'xfs_repair -n <dev>.' This will attempt
a dry-run (e.g., no modifications) check and repair of the filesystem.
