You can lower LEASE_LIFETIME and GRACE_PERIOD to shorten the time it's in grace, to make it more bearable. Making export changes dynamic is something that's fixed in newer versions of nfs-ganesha than what's shipped with Scale:
https://github.com/nfs-ganesha/nfs-ganesha/releases/tag/V2.4.0: "dynamic EXPORT configuration update (via dBus and SIGHUP)" Hopefully someone can comment on when we'll see nfs-ganesha v2.4+ included with Scale. -jf On Mon, Oct 23, 2017 at 12:41 PM, Peinkofer, Stephan < [email protected]> wrote: > Dear List, > > I’m currently working on a self service portal for managing NFS exports of > ISS.
