The number of resources shouldn't be the main criteria for setting this parameter, but what can your nodes handle without being overloaded. So, 64 sounds sounds like you have some really big computers :) It also depends on the nature of the cluster resources. The default of 4 is rather conservative, perhaps nowadays 8 would be better. > Is it acceptable for lrmd and Pacemaker ? Or will we face any side-effect > ? LRMD_MAX_CHILDREN is the maximum number of resource operations allowed to run in parallel. Hope that that answers your question.
