From: =?utf-8?Q?Stefan_Bauer?= To: =?utf-8?Q?linux-nfs=40vger=2Ekernel=2Eorg?= Date: Fri, 26 Sep 2014 17:08:15 +0200 Mime-Version: 1.0 Content-Type: text/plain; charset=utf-8 Message-Id: Sender: linux-nfs-owner@vger.kernel.org List-ID: 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
