| + | Setting Up The Client | ||
| + | With NFSv4, all of the shares are located under one main export. Therefore, the client only needs a single mount point. We now need to create the mount point for our connection. For this Trail, we'll use the name of the NFS server as the mount point name. | ||
| + | |||
| + | |||
| + | The client mount configuration is set in the /etc/fstab file. Although all of the exports on the server are located under "/exports", the configuration needs to specify the root connection of "nfs1:/" and not "nfs1:/exports". Using the "/" (root) mount instructs the client to connect to the root share which was earlier configured on the server with the "fsid=0" option. Note that we are using the "sec=krb5p" option, to mount using Kerberos credentials. | ||
| + | |||
| + | <cli prompt='#'> | ||
| + | [DIRxSRVx10:root@client ~]# mkdir /mnt/nfs1 | ||
| + | [DIRxSRVx10:root@client ~]# vi /etc/fstab | ||
| + | |||
| + | nfs1:/ /mnt/nfs1 nfs4 sec=krb5p,auto,rw,nodev,sync,_netdev,proto=tcp,retry=10,rsize=32768,wsize=32768,hard,intr 0 0 | ||
| + | </cli> | ||
| + | |||
| + | Now that the connection is configured on the client, the mount can be established with the following command. | ||
| + | <cli prompt='#'> | ||
| + | [DIRxSRVx10:root@client ~]# mount /mnt/nfs1 | ||
| + | </cli> | ||
| + | |||
| + | The share can also be mounted on the command-line. Note that we are providing the "-o sec=krb5p" option, to mount using Kerberos credentials. | ||
| + | <cli prompt='#'> | ||
| + | [DIRxSRVx10:root@client ~]# mount -t nfs4 nfs1:/ /mnt/nfs1 -o sec=krb5p,async,auto,exec,_netdev,nodev,rw,retry=5,rsize=32768,wsize=32768,proto=tcp,hard,intr | ||
| + | A listing of the mounted share shows whether the connection was successful. | ||
| + | |||
| + | [DIRxSRVx10:root@client ~]# mount -l | ||
| + | nfs1:/ on /mnt/nfs1 type nfs4 (rw,addr=10.0.0.2) | ||
