[gpfsug-discuss] control which hosts become token manager

[Billich Heinrich Rainer (PSI)]

Hello,

I want to control which nodes can become token manager. In detail I run a virtual machine as quorum node. I don’t want this machine to become a token manager - it has no access to Infiniband and only very limited memory.

What I see is that ‘mmdiag –tokenmgr’ lists the machine as active token manager. The machine has role ‘quorum-client’. This doesn’t seem sufficient to exclude it.

Is there any way to tell spectrum scale to exclude this single machine with role quorum-client?

I run 5.0.1-1.

Sorry if this is a faq, I did search  quite a bit before I wrote to the list.

Thank you,

Heiner Billich
