My only thought is that in essence, you did a database reorg on the new
instance, and left big holes in the databae on the old instance.  When
we split databases, we had to do a reorg on the old instance to free up
the space.

I would have to agree there seems to be an issue. I just recently split my 
enviroment to 2 tsm servers. I have exported over 1\2 the nodes and 55 percent 
of the files to the new server. Before the split server a db size was 80 gb 91% 
full. After the split server b's db is 20 gb and like I said it has more files 
than server a.
After deleting the nodes from server a I still have 90 % of the 80 gb database 
taken up and expiration does run to completion daily.
Thoughts?

It's just a shot in the dark, but the last time this kind of thing
started happening, W2K system objects weren't being expired correctly
and it was these filespace occupancies that were clearly increasing the
db and storage. I say 'clearly', it only really became evident after 6
months.

I'm not at this level of code, so can't check and I would hope that I am
wrong and the bug hasn't been reintroduced, but it is something to look
at and check off the list as not being the problem.

May want to check W2K3 system state and system services also.

Graph your occupancy (num_files) by domain for each server and see if it
shows uniform growth.

If not, drill down to node occupancies (num_files), and so on.

I might have thought that too if it wasn't all 3 instances. I graphed my
database sizes back to 2004 (I have them in a mysql database), and it is
striking the growth curve since 11/12/2005.

On November 11th, we upgraded our 3 tsm instances from 5.2.1 to





5.2.4.5.  Since then, our three databases have grown at an alarming





rate.  They have grown:

56GB to 75GB (33%, 19Gb growth)
46GB to 65GB (41%, 19Gb growth)
53GB to 63GB (18%, 10Gb growth)

Anyone have problems like this?  Thanks.
