AFAIK you cannot change the kernel's view of the partition size while
the partition is mounted.  Adding the extra disk has to be done with
the partition (and hence the filesystem) offline.  xfs_growfs works on
mounted filesystems.  My comment mistakenly merged the two, quite
separate, requirements.
