Cette fiche retrace les opérations effectuées lors de la mise en place d'une surveillance NFS.
La VM Libux ne disposait pas de 'showmount' pour lister les montages disponibles sur un serveur distant :
# showmount -e serveurdistant
-bash: showmount: command not found
[11:18:28] root@sec-mut-test1:~ # yum install showmount

This system is not registered with an entitlement server. You can use subscription-manager to register.

Nous essayons alors de monter un FS AIX :
# mount -t nfs serveurNFS:/exports /mnt
mount.nfs: rpc.statd is not running but is required for remote locking.
mount.nfs: Either use '-o nolock' to keep locks local, or start statd.
mount.nfs: an incorrect mount option was specified
Il est possible de rajouter l'option '-o nolock' pour effectuer le montage mais ce n'est pas la meilleure solution.
Vérifier que le service 'rpcbind' est actif. Sinon, démarrez-le :
# service rpcbind status
rpcbind is stopped
# service rpcbind start
Starting rpcbind: [ OK ]
Vérifier que le service 'nfslock' est bien actif :
# service nfslock status
Les fichiers de configuration des montages NFS sont '/etc/fstab' et '/etc/nfsmount.conf'.
