Comment: /pj-rehearse auto-ack to run up to 5 rehearsals, and add the rehearsals-ack label on success
Comment: /pj-rehearse list to get an up-to-date list of affected jobs
Comment: /pj-rehearse abort to abort all active rehearsals
Comment: /pj-rehearse network-access-allowed to allow rehearsals of tests that have the restrict_network_access field set to false. This must be executed by an openshift org member who is not the PR author

If you would like the rehearsals-ack label removed, comment: /pj-rehearse reject to re-block merging.

Is there also a MASTER_VCPU setting? Should we rely on the default, or nail it down to what we want (i think its 4)?

Sure, the default right now is 8vCPUs for master, do you want to try 4vCPUs for master?

Thx, no, not yet. 8 vCPU (4 Cores with HT) is the current min sys reqs for regular OCP CP nodes. Let keep that and focus on the arbiter first.
