Client For Nfs Service
Hi, I’ve updated an old version 4.0 system step by step to 4.3. Now NFS refuses to start. When I try to start it I get: root@server:# systemctl start nfs-server.service Job for nfs-server.service canceled. I'm trying to get nfs working on an Ubuntu 16.04.2 LTS. I get the following error: I've already tried reinstalling nfs-common, nfs-kernel-server and other packages following instructions provided in.
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:
Server For Nfs
4. Check the status of NFS service:
5. Create a shared directory: Software buy for mac.
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:
Eample :
This example does the following:
– It mounts /home from remote host (remote_host) on local mount point /remote_home.
– File system is mounted read-only and users are prevented from running a setuid program (-o ro,nosuid options). Easycap for mac os x.
3. Update /etc/fstab to mount NFS shares at boot time.
