Does anyone know where a good resource for NFS4 ACLs can be found?

  • 772

I am attempting to utilize NFS4 ACL's in an environment already utilizing POSIX ACL's. I've found a handful of sites on the internet that explain some technical details about NFS4 ACL's and how they're created, but the tools seem to fail for me when I try to execute them.

Does anyone have a good resource/tutorial to explain how to setup NFS4 ACLs?

When I try to change the ACL set from the server:

[root@ny-bar01 foo_server]# nfs4_setfacl -e /nfs/obfuscate/
Operation to request attribute not supported.
Failed to instantiate ACL.

When I try to change the ACL set from the client:

[root@ny-baz02 foo_client]# nfs4_setfacl -R -e .
Failed setxattr operation: Operation not permitted
An error occurred during recursive file tree walk.
linux nfs access-control-list posix

    For the record, we found out that ext4 does not natively support NFS ACL's. There are a few filesystems with experimental NFS4 ACL support, but, experimental is not the word I want attached to my production environment.
