Ok, this is an almost empty database with a lot of fragmentation.

I'd say, from what I read in the thread, that an unload/load at this
point will remove a lot of fragmentation, even though the estimate
says nill.

The other option is to run an export server, reformat everything, and
then import server. You'll probably want to save your devconf.txt so
you can easily recreate the stgpools, devclasses and server2server
comms you might have.

With an assigned capacity of 52GB yet only 0.1% utilized (52MB?), it
says
I can only reduce the DB by 13GB ????

So, where is the remaining 38GB of DB usage ?

There are 5-Disk STG volumes (empty/0% utilized), 2-Nodes with NO
filespaces, defined.  "Q STG" shows:

I did a "DSMSERV AUDITDB FIX=YES"  and the only thing it complained
(and
fixed) about was old schedules for non-existing nodes.  Also did an
"EXPIRE INVENTORY".
