After upgrading from OES 2 Linux to OES 11 or later server, errors occur when trying to use DFS on the upgraded server.
The /var/opt/novell/dfs is the default location for the VLDB database files. It is automatically created during a fresh install, and should also be automatically created for an upgrade. The DFS plug-in to NetIQ iManager assumes that the default directory exists and does not create it for you if you accept the default location when using the server as a DFS replica site. Because the path does not exist, the VLDB initialization process fails, and the VLDB file is not created.
To resolve this problem:
Create the /var/opt/novell/dfs directory as the root user, and set its POSIX permissions to mode 755 (rwxr-xr-x).
In iManager, remove the server as a replica site, then add the server as a replica site to create the VLDB on this server.
If removing and adding the server as a DFS replica site does not cause the VLDB to be created, you can force the file to be created by reinitializing the database using the vldb -init command.
WARNING:Before you use the -init option, see Section A.1.4, Hidden VLDB Command.
Enter the following command at a terminal console prompt as the root user:
Go to the /var/opt/novell/dfs directory, and verify that the database file was created.
Start the VLDB services.
