We have 2 Data domain DD690's in 2 sites connected by a 100mbps dedicated link. We use SLP's to drive data between them. The DDR in our DR site has longer retentions on it's images than the primary site, so has more data on it.
We have seen a problem after a DDOS upgrade where Netbackup is reporting vastly skewed space on the DDR’s through the disk pools view. Previous to upgrade we were seeing 20Tb Raw, 16Tb used and 3Tb free. (77% used) After the upgrade I see. 316Raw, 312used 3.7free (98%full) We got some errors telling us the DR box had breached the high water mark, which according to NBU, it has however this is not the case and I believe the OST plugin is reporting incorrectly, or Netbackup is interpreting the data incorrectly. The DDR itself confirms that nothing drastic has changed and it is still 20/16/3 (77%)
As a workaround I have increased the High Watermark to 100% in the hope that no matter how badly the numbers are skewed. It will never report 100% as I think the reported numbers are relative to the deduped data on the DDR (Hope that makes sense, I think it does!)
what I need to know is:
Thoughts anyone?
Many Thanks
Matt

Please double-check your link - it is this very same thread!

This is the link Rugby01 was referring to
http://www.symantec.com/business/support/index?page=content&id=TECH135174&actp=search&viewlocale=en_US&searchid=1291079293889
The fix is not out yet, or maybe only available on request.

The TN Riaan gave is the correct one. And he's right, available only on request.
Though the binary fix is not referenced using that number (not directly, it's a sibling)
(ET2085566) BUG REPORT: After an update of the OpenStorage (OST) plug-in to version 2.2.1.1, NetBackup may report status code 129 and "EMM status: Insufficient disk space or High Water Mark would be exceeded Disk storage unit is full(129)" more frequently due to a change in the method of calculation of free space on the storage unit.
Open a case at Symantec's CC:
Online: (On the right, MySupport tab => "Create a support case" )
http://www.symantec.com/business/support/index?page=landing&key=15143
Or call the CC:
http://www.symantec.com/business/support/assistance_care.jsp
And ask for ET2085566 .. provide your NBU version, and which OS versions & architectures are running on your Master & Media Servers (the ones attached to the DD box)
You'll need to install the fix on your Master, and all the Media's connected. (service restart required)

Has this problem been seen at an OST version higher than 2.2.1.1? We are seeing skewed numbers at version 2.2.2.0, we are not getting the error 129 because HWM is already at 99%

Hi Telva-boy
Just to let you know, we (symantec) don't support the use of boost on a netbackup media server....yet....
****EDIT**** Unfortunately I cannot provide proof so talk to a Symantec SE about it.

Running OST 2.2.2.0, DD OS 4.9.2.6
I don't have problems..

Bringing back from the dead even though this is a late reply. I'll agree to disagree with you.
While Symantec supports OST and EMC/DD's OST plug-in, they don't support the value add of "BOOST," within the plug-in. Why? Well it competes with their own products. I understand this marketing decision.
That said, your blanket statement of Symantec doesnt support boost is incorrect and misleading. And talk to a Symantec SE, and you'll find the same answer. (You don't know my background and how intimately I know Symc products, SE's, and PM's in your org. ;) ...)
