Coexistence considerations

Each GPFS™ cluster can have multiple GPFS file systems that coexist on the cluster, but function independently of each other. In addition, each file system might have different data management programs.

Note: The GPFS Data Management API (DMAPI) and GPFS file system snapshots can coexist; however, access to the files in a snapshot using DMAPI is restricted. For more information, see IBM Spectrum Scale: Data Management API Guide.
