I have a very odd situation on my new Linux server/disk pool, as
described in the subject.

Here is the "Q STGPOOL"

                             CRC Data: No
                     Reclamation Type:
          Overwrite Data when Deleted:

It says 77% utilized but nothing migratable.  Trying to MIG STGPOOL says
"nothing to migrate" yet doing a BACKUP STGPOOL is running and backing up.
 I did an audit on one of the disk volumes and it said "yup - there is
something in there and it is OK/no problems".

As you can see, caching is NOT turned on (never have used that feature -
usually too much traffic flowing through to make it of any value).....and
what is with the "Pct Logical" is 100%?

This is a server I upgraded from 5.5.  The disk pools were recreated from
scratch so it's not like there was anything left behind......
