Thought I'd mention that I'm in the process of moving my 1TB backup pool
from one jfs array to another on the same system.  Both arrays are RAID-5
via mdadm.

I'm using "rsync -avP -H src dest," which I started Friday, nearly five
days ago.

The data in cpool moved relatively quickly.  On the other hand, rsync has
been re-establishing hard links to the pc directories for quite a while,
and has quite a ways to go.  On the plus side, it's showing no signs of
stopping or running out of resources, so it looks like it will do the job
... eventually.
