Thanks for the reply.

Ok, Here's the info from multi-user mode.

In single user mode the 'home' pool (second drive) doesn't show up in
status or list or anything, which is fine.
When I boot into single user mode / read only then /usr/home has 100gb
of backup. If I reboot to multi-user or mount read-write in single
user then the files in /usr/home disappear. (even if the second drive
isn't mounted). The 80 GB avail should be like 180GB I think, it's a
250GB drive. The usage stats don't change if the files in /usr/home
appear or not.

The home directory for the second drive is /home which isn't a link to
/usr/home or vice-versa AFAIK. in multi-user mode /home has my files,
/usr/home is empty. in single-user read only , /home is empty and
/usr/home has the backup files.
