[gpfsug-discuss] mm'add|del'node with ccr enabled

[Grunenberg, Renar]

Hallo Eric,
our experiences are add and delete new/old nodes is working only if this node is no quorum node in an ccr cluster, no problem. There are no mmshutdown steps necessary. We are on 4.2.3.6. I think this is already available since >4.2. If you want to add a new quorum node, than you must put this node first as a client and after that you can change this node to a quorum node.

Betreff: [gpfsug-discuss] mm'add|del'node with ccr enabled

Hello:

If I recall correctly this does not work...correct?  I think the last time I attempted this was gpfs version <=4.1.  I think I attempted to add a quorum node.

The process was that I remember doing was mmshutdown -a, mmchcluster --ccr-disable, mmaddnode yadayada, mmchcluster --ccr-enable, mmstartup.

I think with ccr disabled mmaddnode can be run with gpfs up.  We would like to run with ccr enabled but it does make adding/removing nodes unpleasant.

Would this be required of a non-quorum node?

Any changes concerning this with gpfs version >=4.2?
