We had an issue with our mdsp storage filling up yet plenty of space was available from within NetBackup.
Netbackup does not reflect the "actual" disk space available. If you browse using explorer you can check for log files that may fill it up.
However, run this command if you haven't already:
\\installpath\veritas\pdde crcontrol --dsstat.
Look for the space that requires compacting. This can grow very large and can fill up all available space without showing up anywhere. It should look like something below (see bold text). Ours blew out to 10TB.
D:\Program Files\Veritas\pdde>crcontrol --dsstat

Use "--dsstat 1" to get more accurate statistics
I hope this helps.

Also, we experience media write errors when compaction is running with the 100 switch.
x:\program files\veritas\pdde crcontrol --compactstart 100 0 1.
The msdp is too busy to write to the disk.

Hi guys,
Im still stuck with this issue, below is the dsstat info. Can anybopdy let me know why its asking to free up space considering used space is only 14%?

MSDP is more complex component than other,if you encount this issue you can escalate to backline.

This error message indicates your Queue Processing process has failed many times.
" Queue processing failed five times in a row. Queue processing will be disabled"
If you have run crchk before, what did support say about the crchk result? Push them for answer if you don't get one.
There could be some fingerprint files missing or corrupted, this would need a crchk to fix. So the crchk result is the essential one to tell us something.

We had issues with queue processing too. Backline support searched the log file and removed the offending corrupted file and queue processing resumed.
Definitely go to backline. They were very good at helping us out for this.
Sachin Chavan was the support guy who worked with me. If you can't get to him directly tell the support worker you are working with to check with him. He seems to be the MSDP expert.
