Sorry for the duplicate message, my mailer is a bit strange.

I have just installed a test version of adsm server v3.1.2.40 for
os/390.  os/390 v1.3.

As a test, I created a two volume disk pool of total size 421mb.  at
this point I backed up the /usr filesystem using hpux client v2.6.

The backup failed with a server out of storage space message.
However, total size of /usr is 320mb.

Any ideas out there?
