What kernel version? i.e. uname -r
At the time of the mount failure, what do you get for:
$ lsmod | grep xfs
xfs 1892352 0
$ dmesg | grep -i xfs
[ 717.658384] SGI XFS with ACLs, security attributes, scrub, quota,
no debug enabled
I suspect you get neither of the above results. Try:
$ sudo modprobe xfs
Now try mount. Does that work?
