I have tried run xfs_repair -L /dev/sdb (umount the device first)
It seems the partition is repaired now.
Here is xfs_info output

Note that this is a distro kernel...

It looks like something is up with an allocation btree block. The output
of 'xfs_repair -n' would be interesting. You might also want to provide
some basic info about the fs (xfs_info), etc.:
