I'm on 4.6-RELEASE. When I unmounted and remounted the base hammer filesystem it showed a matching size. But when I stop the mirror-stream and mount the former-slave PFS, I have no data to show for it. After a reboot the size is off again.
I'm a little confused about what's actually going on with it at the moment. Data appears to be there but inaccessible. I think that bug is related to what I'm seeing.
