Short answer is that if you want to change/remove the NSD server config on an NSD and its part of a file systems, you need to remove it from the file system or unmount the file system. *Thankfully* this is changed in Scale 5.0.
In your case (host name change) – if the IP address of the NSD server stays the same you *may* be OK. Can you put a DNS alias in for the old host name? Well, now that I think about it the old host name will stick around in the config – so maybe not such a great idea.

Subject: [EXTERNAL] [gpfsug-discuss] Dual server NSDs
Can I remove one of these servers? The object is to upgrade this server and change its hostname, the physical server will stay in place.
Has anyone carried out an operation similar to this?
