Configuring file system ACL by using GUI - IBM
Configuring file system ACL by using GUI. Managing ACLs works only when the file system supports NFSV4 ACL semantics. If the file system supports both POSIX and NFSv4 ACLs, the GUI reads the POSIX ACL in a compatible mode and while modifying the ACL, it overwrites POSIX ACLs with NFSV4 ACLs.
Exceptions and limitations to NFS V4 ACLs support - IBM
Ganesha supports NFS v4 ACLs to and from IBM Spectrum Scale. However, to export a file system with cNFS/KNFS, you must configure the file system to support POSIX ACLs. Use the mmcrfs command with the -k all or -k posix parameter. With Samba, use the -k nfs4 parameter.
File system ACL - IBM
If the file system supports both POSIX and NFSv4 ACLs, the GUI reads the POSIX ACL in a compatible mode and while modifying the ACL, it overwrites POSIX ACLs with NFSV4 ACLs. When only POSIX is supported, writing ACLs through the GUI fails.
Creating a fileset by using GUI - IBM
Note: Only NFSv4 ACL semantics are supported in the GUI. The Edit Access Control section is not shown when creating filesets in a file system that supports only POSIX ACL.
mmeditacl command - IBM
Use the mmeditacl command for interactive editing of the ACL of a file or directory. This command uses the default editor, specified in the EDITOR environment variable, to display the current access control information, and allows the file owner to change it.

Authorizing file protocol users - IBM
When only POSIX is supported, writing ACLs through the GUI fails. You can manually enter the ACL values or define a template to load the standard values that are defined based on your requirement. The IBM Storage Scale system uses ACLs to authorize users who access the system through file protocols such as NFS and SMB.
Access rights and ACL management of clients - IBM
By using the Storwize V7000 Unified GUI or CLI, you can now manage access rights. For example, you can create and edit ACLs for file systems, filesets, and share paths. Also, you can create ACL templates and load ACLs from an existing template while you create or modify file systems, filesets, and shares.
Authorization limitations - IBM
The GUI and the CLI display all ACLs in the NFSv4 format. Displaying ACLs in the NTFS style is not supported. Displaying or setting ACLs in Security Descriptor Definition Language (SDDL) is not supported.
Backing up and restoring Btrfs file systems - IBM
For example, if you copy a file by using the cp command with the -p or -preserve options (preserve mode, ownership, and time stamps), and if the file’s attributes are changed, the access ACL extended attribute (system.posix_acl_access) is changed.
