Thank you to everybody for their help and suggestions. I went ahead and
disabled hardware compression on my drive.
Unfortunately, I am running into further problems in my attempts to
clear out the previously spooled dumps with amflush. amflush fails
after a short time without writing anything at all to tape.
Here is what happens...
I rum amflush and get the following output:
Scanning /local0/ambackup/nextrials...
20030703: found Amanda directory.
20030704: found Amanda directory.
Multiple Amanda directories, please pick one by letter:
A. 20030703
B. 20030704
Select directories to flush [A..B]: [ALL]
I get the same results, whether I pick A, B, or ALL. The amflush report
looks like:

This is frustrating, I need to get the spool disk flushed or else
backups will fail completely tonight due to lack of space.
Amanda has been chugging along just fine for over a year, this problem
has just now crept up as my ammount of data storage has grown.
Thanks again, you folks are super helpful!
