Commvault tape backup software


This error would be returned on certain containers in the nds tree. Others would backup fine. Tests were done with tsatest, which worked fine. All containers were backed up.

The tape backup software had errors in their logs like this:
  Galaxy.log?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />       
      32243 b554b6b0 04/14 13:43:53 25650 NWSMTSScanDataSetBegin<edirectory context> returned (90000009), Unknown SMS error - 0x90000009.

The problem only happened on certain containers in the nds tree. If these containers were backed up individually, it worked fine.


There were around 1000 containers in edirectory, in this case. The problem was that  CommVault, during their scan of edirectory, was making a new connection for each container in the nds tree.There was a 1024 open files limit on the machine being backed up. This was increased to 5000 using

 'ulimit -n 5000'.

'fs.file-max = 5000000' in /etc/sysctl.conf
  or  sysctl -w fs.file-max=5000000

After making these changes it is necessary to restart smdr and edirectory for the changes to take effect.
rcnovell-smdrd restart
rcndsd restart
This should be done after hours if possible or when as few users as possible are on the system. Rcndsd restart will unload and reload directory services.
Rebooting the host will accomplish the same thing.
All containers in the nds tree could be backed up with Commvault after making these changes

If setting the files to 5000 does not resolve the issue, then set it to a higher number. This can happen if the there is a large number of edirectory containers.

Additional Information

CommVault makes a new connection for every NDS container it backs up. To do this, it also opens a socket descriptor for each connection. Socket descriptors are files in Linux. This was a case of running out of open files.
