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

DFS interoperability

GPFS and DFS for AIX may interoperate to support the export of a GPFS file system to DFS clients. A GPFS file system may be exported from one node using the DFS export protocol. After export, normal access to the file system may proceed from the SP nodes or DFS client nodes.

Considerations for the interoperability of a GPFS file system include:

• Exporting a GPFS file system via DFS
• DFS usage of GPFS cache
• Unmounting a DFS exported file system
• DFS file size limits
• GPFS quotas and DCE foreign cell users
