The doc looks good

Thanks Poornima.

Moving the bug to ON_QA.

There is small change required for this section:

The following text :
====================
 Execute the following commands to enable negative-lookup cache:

    To enable cache invalidation and increase the timeout to 10 minutes execute the following commands:

    # gluster volume set <volname> features.cache-invalidation on

    volume set success

    # gluster volume set <volname> features.cache-invalidation-timeout 600

    volume set success

    To enable negative-lookup cache execute the following command:

    # gluster volume set <VOLNAME> nl-cache on
    volume set success

    Note
    By default the cache time is 10 minutes. It is recommended to retain the default value. 


Should be changed to:
====================
 Execute the following commands to enable negative-lookup cache:

    To enable negative-lookup execute the following commands:

    # gluster volume set <volname> group nl-cache

    volume set success

    The above command also enabled cache-invalidation and increase the timeout to 10 minutes

Looks good to me. Marking it as Verified.
