NFS and nobody sur la baie SAN

Le gid 551 est mappé en nobody sur les NFS :

root@stored-m:~> mount | grep ' nfs '
compellent-nas-sma.in.ac-versailles.fr:/bkp_stored on /stored2/SAUVEGARDE_IMAP type nfs (rw,user=root,noexec,nosuid,nodev,vers=4,addr=172.31.136.251,clientaddr=172.31.131.59)

root@stored-m:~> touch /tmp/foo /stored2/SAUVEGARDE_IMAP/foo
root@stored-m:~> stat --format '%n => %U(%u):%G(%g)' /tmp/foo /stored2/SAUVEGARDE_IMAP/foo | column -t
/tmp/foo                      =>  root(0):root(0)
/stored2/SAUVEGARDE_IMAP/foo  =>  root(0):root(0)

Problem to start OSD via the docker image ceph/daemon

To start the OSD docker:

~$ docker run -d --name=osd1 --restart unless-stopped --net=host --privileged=true \
       -v /etc/ceph:/etc/ceph -v /var/lib/ceph/:/var/lib/ceph -v /dev/:/dev/       \
       -e OSD_DEVICE=/dev/sdb ceph/daemon osd_ceph_disk

But the start fails:
