Why Filesystem ACL commands like `setfacl` and `getfacl` does not work on NFSv4 mounted filesytem?

Solution Verified - Updated -

Environment

  • Red Hat Enterprise Linux
  • NFSv4.x

Issue

  • ACLs do not work with NFS4 shares, as normally expected.

  • Commands like setfacl and getfacl fails for NFS mount.

    Raw
        $setfacl -m u:test:r file 
    setfacl: file: Operation not supported

Resolution

Root Cause

  • Support for Linux ACLs over NFSv4 is not stable enough in upstream for inclusion into RHEL.
    Also, the design of NFS4 makes it almost impossible to completely emulate Linux ACLs.

  • ACL support for NFS4 mounted file system is not available in Red Hat Enterprise Linux. Following
    bugzilla explains the same: setfacl not supported on NFSv4 mounted filesystem
