Note: The information in this section assumes that your vendor has properly configured your operating system's mount command (or its equivalent) to handle DCE LFS filesets. If this is not the case, the operations described in this section do not apply.
In addition to being exported for use in the DCE namespace, DCE LFS filesets can also be used locally, as file systems on their File Server machines. To use a DCE LFS fileset locally, use your local operating system's mount command (or its equivalent) to mount the fileset on the local disk of the machine.
Mounting a DCE LFS fileset locally does not improve access time to data in the fileset if the fileset is accessed via a DCE path name. However, access time to data in the fileset is improved if the fileset is accessed via a local path name. Availability of the fileset is also generally improved because the fileset can still be accessed via a local path name in the event of a network outage. If data in a DCE LFS fileset that is physically located on the local disk of your machine is available only through the DCE namespace, a network outage makes it impossible to access the data.
Provided the DCE LFS aggregate that contains a fileset is exported and the fileset is mounted in the DCE namespace, you can also access a locally mounted DCE LFS fileset globally. The path name associated with the fileset is different for local and global access. For example, a fileset that is accessed in the local operating system as /usr/jlw may be accessed in the DCE namespace as /.../abc.com/fs/usr/jlw.
Note: A DCE LFS fileset that is mounted locally cannot be moved to a different File Server machine (with the fts move command), and it cannot be deleted (with the fts delete or fts zap command); you must unmount it locally before attempting any of these operations. Also, an aggregate that houses a locally mounted fileset cannot be recovered or salvaged with the salvage command, nor can it be reinitialized with the newaggr command.
The following instructions describe the steps involved in mounting a DCE LFS fileset locally. It is assumed that the aggregate that houses the fileset has already been initialized with the newaggr command and that the fileset to be made available locally has already been created with the fts create command.
1. Log in as root on the machine. For example, issue the following command:
$ su root
Password: root_password
2. Create an empty directory on the local machine to serve as the local mount point for the fileset. For example, issue the following command:
# mkdir directory_name
3. Use the mount command for your local operating system to mount the DCE LFS fileset just as you would a non-LFS partition. The local mount command may be modified for DCE LFS; for example, the mount command may be altered to accept a fileset ID number, in which case you would specify something like the following:
# mount device_name directory_name fileset_ID
Note: If your vendor has properly configured your local operating system, you may be able to mount DCE LFS filesets automatically at system startup by including the proper information in an initialization file (fstab or its equivalent). Refer to your vendor's documentation for more information about mounting file systems at system startup.
