[gpfsug-discuss] Question regarding quorum nodes

[Danny Lang]

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

This will allow you to add quorum nodes and to remove.

------

I would advise checking everything prior to running commands. 🙂

Thanks
Danny

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
