Hello Community, 

We have that configuration: 

  1. File server with DFS namespaces on Windows machine. 
  2. Archive solution with Windows File System Archiving on the same machine. 

and time to time, DFS service is blocked by Commvault  which stopped shared files to users. According to Microsoft investigation there is a file which working in the same time and can provided that issue: 

E:\System Volume Information\Commvault\Data Classification\dc_001.db-journal

Does someone have that type of problem? Is possible to move somewhere that DB from Commvault site, to not stop DFS service?

Regards, 

Michal

Hi Michal,

 

That particular file referenced is the metadata database for our scanning mechanism (to catalog file/folder modification). Source: https://documentation.commvault.com/v11/expert/file_scan_methods_for_windows_file_system_agent.html

 

When you state that the DFS service has been blocked by Commvault, are you saying that the DFS service has been stopped, disabled, or both?

 

I wonder if this has to do with the system state backup of the file server itself which we can possibly look to exclude the non-critical DFS replication service from being taken. Source:

Hello ​@Jon Vengust 

About configuration, we don’t backup system state. The file server typical is backup-ed by VSA client, so we have backup entire machine if it is necessary. But we use Archive Client only for old files to do Stubing, to not keep the old data on cost storage in Azure. 

Regards, 

Michal
