Increasing the Size of a Journaled File System that is under the Control of a DLFF on AIX

This section describes how to increase the size of a Journaled File System using a Data Links Filesystem Filter on AIX. This section does not apply to DCE-DFS environments.

To allocate more space to an existing file system that is using a Data Links Filesystem Filter:

1. Log in as a user with root authority.
2. Modify the properties of the file system so that it is no longer under the control of the Data Links Filesystem Filter, and unmount it, by entering the following command:

       /usr/lpp/db2_07_01/instance/dlfmfsmd -j filesystem_name
   

   where filesystem_name specifies the name of the mounted file system that is using the Data Links Filesystem Filter.

3. Enter the smit jfs command and increase the size of this file system.
4. Modify the properties of a file system so that it comes under the control of the Data Links Filesystem Filter, and mount it, by entering the following command:

      /usr/lpp/db2_07_01/instance/dlfmfsmd dlfm_mountpoint
   

   where dlfm_mountpoint is the mount point of the JFS file system that you created for the Data Links Filesystem Filter in the previous step.

5. Log out.
