Subject: posix acl to nfs4 acl mapping - status?
Date: Fri, 26 Sep 2014 17:08:15 +0200	[thread overview]
Message-ID: <zarafa.5425815f.6e31.1b72722237f64a60@srv1.localhost> (raw)

Hi,

I'm just a regular sysadmin and want to use NFS4 shares for backup purpose and keep existing posix acls from local filesystems during transfer.

It seems to not be supported:

root@s1:/# mount.nfs4 -o acl 192.168.0.254:/ /bla
root@s1:/# cp -Rvp omg /bla/
‘omg’ -> ‘/bla/omg’
cp: preserving permissions for ‘/bla/omg’: Operation not supported

What is the status on that? I'm aware of nfs4_getfacl but dont want to adjust permissions manually.

I also found https://tools.ietf.org/html/draft-ietf-nfsv4-acl-mapping-05 which describes a working algorithm for posix->nfs4 mapping but no evidence whether this is implemented and if so - how.

I'm using Debian testing with kernel 3.14.3.4 #5 SMP Thu May 8 16:31:22 CEST 2014 x86_64 GNU/Linux.
mount.nfs4: (linux nfs-utils 1.2.8)

Kind regards

Stefan
