When i restart the nfs-kernel-server it gives me a notification that the job is cancelled. $ sudo service nfs-kernel-server restart. And this is the output when i restart nfs kernel server $ Job for nfs-server.service canceled.

NFS allows a linux server to share directories with other UNIX clients over network. NFS server exports a directory and NFS client mounts this directory. RHEL 7 supports two version of NFS – NFSv3 and NFSv4.

NFS server and RPC processes

starting the nfs-server process starts the NFS server and other RPC processes. RPC processes includes:
– rpc.statd : implements monitoring protocol (NSM) between NFS client and NFS server
– rpc.mountd : NFS mount daemon that implements the server side of the mount requests from NFSv3 clients.
– rpc.idmapd : Maps NFSv4 names and local UIDs and GIDs
– rpc.rquotad : provides user quota information for remote users.

Configuring NFS server

1. Install the required nfs packages if not already installed on the server :

2. Enable the services at boot time:

In RHEL7.1 (nfs-utils-1.3.0-8.el7) enabling nfs-lock does not work (No such file or directory). it does not need to be enabled since rpc-statd.service is static.

In RHEL7.1 (nfs-utils-1.3.0-8.el7) this does not work (No such file or directory). it does not need to be enabled since nfs-idmapd.service is static.

3. Start the NFS services:

4. Check the status of NFS service:

5. Create a shared directory:

6. Export the directory. The format of the /etc/exports file is :

Client options include (defaults are listed first) :
ro / rw :
a) ro : allow clients read only access to the share.
b) rw : allow clients read write access to the share.
sync / async :
a) sync : NFS server replies to request only after changes made by previous request are written to disk.
b) async : specifies that the server does not have to wait.
wdelay / no_wdelay
a) wdelay : NFS server delays committing write requests when it suspects another write request is imminent.
b) no_wdelay : use this option to disable to the delay. no_wdelay option can only be enabled if default sync option is enabled.
no_all_squash / all_squash :
a) no_all_squash : does not change the mapping of remote users.
b) all_squash : to squash all remote users including root.
root_squash / no_root_squash :
a) root_squash : prevent root users connected remotely from having root access. Effectively squashing remote root privileges.
b) no_root_squash : disable root squashing.

Example :

7. Exporting the share :

-r re-exports entries in /etc/exports and sync /var/lib/nfs/etab with /etc/exports. The /var/lib/nfs/etab is the master export table. Other options that can be used with exportfs command are :

8. Restart the NFS service:

Configuring NFS client

1. Install the required nfs packages if not already installed on the server :

2. Use the mount command to mount exported file systems. Syntax for the command:
