PFS mirror problems

Hi,
I think I must have setup the mirroring incorrectly because nothing is
happening. I tried following the guide "how to implement hammer pseudo
file system( pfs ) slave mirroring from pfs master" on the website but
something appears to have gone wrong.
I have two 7.3tb hammer filesystems spread over two physical disks each
on the same system. I had problems creating the slave PFS so created it
as a master, demoted it, then altered the shared-uuid to match before
trying to mirror it. When I do a mirror-copy I get this result:
# hammer mirror-copy /usr/stor/backups /usr/backup-stor/pfs/backups
Mirror-read /usr/stor/backups succeeded
#
The data is obviously not being copied over:
# df -h /usr/stor /usr/backup-stor
Filesystem Size Used Avail Capacity Mounted on
stor1 7.3T 44G 7.2T 1% /usr/stor
backup-stor1 7.3T 1.0G 7.3T 0%
/usr/backup-stor
As far as I can tell they're setup correctly:
# hammer pfs-status /usr/stor/backups /usr/backup-stor/backups/ | egrep
'(shared-uuid|operating)'
shared-uuid=4138d697-3355-11e5-99b1-e13f494aab78
operating as a MASTER
shared-uuid=4138d697-3355-11e5-99b1-e13f494aab78
operating as a SLAVE
Can someone help point me towards the problem? I feel like I may have
missed something.
Thank you!
