[gpfsug-discuss] Experience with CES NFS export management

As others have answered, 4.2.3 spectrum can add or remove exports without 
restarting nfs-ganesha service. Changing an existing export does need 
nfs-ganesha restart though.

If you want to change multiple existing exports, you could use 
undocumented option "--nfsnorestart" to mmnfs. This should add export 
changes to NFS configuration but it won't restart nfs-ganesha service, so 
you will not see immediate results of your changes in the running server. 
Whenever you want your  changes reflected, you could manually restart the 
service using "mmces" command.

Regards, Malahal.

This becomes very disruptive when you have to add or remove many NFS 
exports.  Is it possible to add and remove multiple entries at a time or 
is this YARFE time?

mmnfs export change --nfsadd   seems to generate a restart as well.
Particularly annoying when the currently running nfs.ganesha fails to
stop rpc.statd on the way down, and then bringing it back up fails because
the port is in use....
