Server Side#

exportfs -v		list exported paths
exportfs -a		export drives specified by /etc/exports
exportfs -au		unexport all drives
exportfs -ra		exports has changed - reset

You can't unmount an exported drive but you can unexport, umount, mount a different drive and export it while others are using the export. The attached machines will have to unmount and re-mount the share, however.

/etc/exports#

/media/disk/	192.168.1.122(rw,sync,no_root_squash)
/media/disk/	192.168.1.0/24(rw,sync,no_root_squash)
	Only the first 24 bits are relevant

You can add more exports to the same drive by repeating the second part separated by a space or with a \ line continuation.
