Configuring Rational ClearCase to support Samba

For all Rational® ClearCase® clients on Windows® that have the MVFS installed and that will access Samba shares, change the MVFS Performance settings in the ClearCase program in Control Panel, as follows:


  1. Click Start > Settings > Control Panel. Start the ClearCase program.
  2. On the MVFS Performance page, Select Override for both Maximum number of mnodes to keep on the VOB free list and Maximum number of mnodes to keep for cleartext free list.
    • If you are using a 64-bit build of Samba 2.2.6 or later, set the value for both to 800.
    • If you are using any other version of Samba, set the value for both to 200.
  3. Click OK to apply the changes and close the window.
  4. Shut down and restart Windows.
