File system authorization
The type of authorization for the file system is specified on the -k option on the mmcrfs command or changed at a later time by using the -k option on the mmchfs command.
- posix
- Traditional GPFS™ access control lists (ACLs) only (NFS V4 and Windows ACLs are not allowed).
- nfs4
- Support for NFS V4 and Windows ACLs only. Users are not allowed to assign traditional ACLs to any file system objects.
- all
- Allows for the coexistence of POSIX, NFS V4, and Windows ACLs within a file system. This is the default.
If the file system will be used for NFS and Swift protocol exports, nfs4 is recommended.
If the file system will be used for SMB protocol exports, nfs4 is required.
