Understanding the Mounting Instructions
The syntax of the fstab entry for remote mounting using NFS is as follows:
exphost:expfs mountpoint fstype options
exphost Specifies the external server that is exporting the file system.
The exporting host can be expressed as an IP address or as a fully qualified domain name.
expfs Specifies the file system that is exported by the exporting host and mounted by the mounting
host.
mountpoint Specifies where the file system should be mounted on the mounting host.
fstype Specifies the file system type. The file system type is nfs.
options Specifies a comma-separated list of options, as defined in mount(8).
The use of the _netdev option is recommended. It informs the system startup scripts that
this file system should not be mounted until the network is up.
An example entry is as follows:
xeno:/extra /workarea nfs rw,_netdev
This means that the node with this fstab file entry mounts the file system named /extra, which is exported
from the system named xeno, and mounts it at /workarea. The file system can be read from and written
to. The _netdev option means that the file system is not mounted until the network is up.
