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 the Programming reference section.
