NFS Server/Client shutdown procedure ?

[subhap]

I need help in determining how to shutdown NFS client and server. I looked up existing documentation and could not find the right way to shutdown either client or servers.
----------------------------------------------------------------------------------------
in /etc/exports on server name: nfs_server
/myhome ftp_server((rw,no_root_squash,sync), http_server(rw,no_root_squash,sync)

On the client side /etc/fstab
nfs_server:/myhome /myhome nfs defaults 0 0
-----------------------------------------------------------------------------------------
Question is, do you unmount the drives before shutting down NFS service on clients, or you shut down services say for http_server = httpd daemon, then nfs, nfslock followed by unmounting of /myhome?

On the server side do you have to unmount /myhome before shutting down NFS services?

thanks

On the NFS Client side, the NFS drives needs to be unmounted before stopping NFS client services: nfs, nfslock.

step1. look at all NFS drives that are mounted: mount [command]
nfs1:/home/services services
nfs1:/home/software /home/software
nfs1:/internet/downloads /downloads

step2. umount /services
umount /home/software
umount /downloads

step3. service nfs stop

-------------------------------------------------------------------------------------
On the server side, the service nfs stop , no need to unmount drives
