Hi,
 I have a DB2 database (version 7) running on Windows 2000 server and
recently facing problem to backup my database. I got an error "Disk
was full" after half way running the backup.  My database size is
about 10GB, I have tried to backup the database into a DDS tape (20GB)
or hardisk (100GB free space) but still getting the same error. So,
there is no possibility that the backup media is full. Anyway, here's
part of db2diag.log file that I captured during the time backup was
failed. You will notice that besides disk full error, there are
prefetcher and buffer pool error as well. Hope it will give some hints
what could be the real cause of this problem.
 TQ!!
