Export

Export without preventing access to the currently exported filesystems.

Add the new filesystem definition to /etc/exports or /etc/exports.d/*.exports and then:

exportfs -av

Mounting NFS Shares

mount -t nfs 10.10.2.131:/opt/nfs0 /mnt/nfs

where /opt/nfs0 is the share exposed by the NFS server.

A non-existent directory on the exported share cannot be mounted - the directory will not be created remotely upon mount. If /opt/nfs0/red directory does not exist, the following command will fail:

mount -t nfs 10.10.2.131:/opt/nfs0/red ./tmp/
mount.nfs: mounting 10.10.2.131:/opt/nfs0/red failed, reason given by server: No such file or directory

However, if the directory is created on the share, the mount succeeds:

ssh 10.10.2.131
sudo mkdir opt/nfs0/red
exit
mount -t nfs 10.10.2.131:/opt/nfs0/red ./tmp/
