Hi,

CephFS currently only supports POSIX ACLs.

These can be used when re-exporting the filesystem via Samba for SMB 
clients and via nfs-kernel-server for NFSv3 clients.

NFS-Ganesha in version 4.0 from Ceph 17 supports POSIX ACLs for the Ceph 
FSAL. But only on the backend, the frontend still only uses NFSv4 ACLs 
as the NFSv3 POSIX ACL side channel is not available.

Are there any plans to harmonize this?

E.g. support NFSv4 ACLs (which are similar to NTFS ACLs AFAIK) natively 
in CephFS which then could be exported via NFS-Ganesha for NFSv4 and 
Samba for SMB.

Or is this too much to be asked as there are three projects involved?

Regards
