hidden:Configuration of the NFS service on ''hpa''

The directory on the HPSS servers for the configuration files is: TBD
With changing to this directory the automount will be active.
The mount will be unmounted after 3 minutes without access.

Configuration on the HPA server (172.18.95.59)

• the directory for the config files was created: /export/hpa

• The file /etc/exports was modified:

      /export/hpa 172.18.95.0/22(rw,no_subtree_check,no_acl,no_root_squash)

• nfs-utils was updated with yum

• nfs was started with systemctl start nfs.service

NFS v3 support

Because RH7 systems like hpa, run NFS Version 4 by default the mount syntax on the client is different as compared to mounting the same directory with the nfs 3 protocol. nfs v4 uses the 'root' directory concept and therefore mount commands must mount the exported 'root'. If the server has the /etc/exports file above then

• nfs v3

 mount -o nfsvers=3 <server>:/export/hpa /mnt

• nfs v4

 mount -o nfsvers=4 <server>:/ /mnt

Also rpcbind has to run on a v3 server (which is real gotcha!).

 systemctl start rpcbind
