NBU 6.5 DSU problems

[Chris_Colvin]

Has anyone else had problems with Staging after moving to 6.5 from 5.1?  I have units that seem to not want to expire the old images, or stage off.   So far I haven't found any problems with restores, just lots of disk full problems.   My solution is to swap them out a few at a time and clean the old ones out manually.

Also, how do I set it so I only have one stream running from disk to tape for the DSUs at a time?  I use the DSUs to concentrate slow, small backups on disk and them move them to tape much more quickly than if they'd been written directly, when NBU spawns off 4 or 5 streams, it kills my read IOs.

Hi,

Have the same problem. Upgraded from 6.0 MP5 to 6.5.2. Now the staging disk get full and I have to expire images manually. It seems to ignore the high water mark. I have opened a case with symantec but still no sollution.

my by the convertion of the image files are not running correctly. Delete all of the old images from NetBackup 5.1 and 6.0 over the Gui!

Perhaps you could limit the number of staging streams by MAX_STAGING_JOBS touch file. This approach did a trick in 5.1.

I was totally wrong in my suggestion. Here is the info on contemporary DSSU behaviour.
