Hi
Do you have quorum loss already, or just trying to remove a node that is
currently offline. Over the years I have had little to no problems
removing quorum from a defunct node. Just make sure mmgetstate for the
node is down and it should be fine to remove, since it's already out of
the cluster.
Just make sure you don't induce quorum loss with the moves. I'd probably
add the node first after making sure the defunct node is completely down.

Thanks - I know the command.
Can I remove quorum functionality from a node that is down - that's
really what I want to know, I think. Is that safe to do?

Hi Tina,
The command you're looking for is:
*mmchnode*
https://www.ibm.com/docs/en/storage-scale/4.2.0?topic=commands-mmchnode-command
<https://www.ibm.com/docs/en/storage-scale/4.2.0?topic=commands-mmchnode-command>
This will allow you to add quorum nodes and to remove.

I would advise checking everything prior to running commands. 🙂
Thanks

External Sender: Use caution.
Hello All,
I hope someone can answer this quickly!
We have - it seems - just lost one of our NSDs.The other took over as it
should - but unfortunately, the protocol nodes (i.e. I have a number of
nodes which now have stale file handles. (The file system is accessible
on the remaining NSD server and a number of other clients.)
Unfortunately, in the 'home' cluster - the one that ones the disks - I
only have, five servers; three of which are quorum nodes, and of course
the failed NSD server is one of them.
The question is - can I add quorum nodes with one node down, and can I
remove quorum functionality from a failed node?
Tina
