IBM General Parallel File System for AIX: Administration and Programming Reference

Exporting a GPFS file system via DFS

To export a GPFS file system:

1. Create and mount the GPFS file system. In the examples, we will assume a file system with a local mount point of /gpfs and a device entry of /dev/gpfs.

   If the file system to be exported was created under a level of GPFS which does not support DFS exporting, you must first migrate the file system using the mmchfs command with the -V option. For further information, see mmchfs Command and Problems DFS Exporting a GPFS File System in the IBM General Parallel File System for AIX: Problem Determination Guide.

2. Ensure DCE and DFS are properly configured and running.

   Information on configuring DCE and DFS, can be obtained at http://www.software.ibm.com/network/dce/library .

3. Export the GPFS file system as a nonlfs file set.

   mkfilesys.dfs -file_system_type nonlfs -fileset gpfs -mountpoint /:/gpfs -device_name /dev/gpfs
