Using oplocks for CIFS storage systems

Oplocks (opportunistic locks) allow CIFS clients to cache more data locally, reducing traffic to the storage system.


  1. If your system is running CIFS and is not in a database environment, enter the following command to set oplocks: options cifs.oplocks.enable on

    Attention: If your system is in a database environment, ensure that the oplocks are not set.

    For more information about the cifs.oplocks.enable option, see the na_options(1) man page.
