Hi Dejan I tried to reproduce the latency pb between commands, bt with only some Dummy resources : Resource Group: group-dummy1 resname1 (ocf::pacemaker:Dummy): Started chili2 resname2 (ocf::pacemaker:Dummy): Started chili2 resname3 (ocf::pacemaker:Dummy): Started chili2 resname4 (ocf::pacemaker:Dummy): Started chili2 Resource Group: group-dummy2 resname5 (ocf::pacemaker:Dummy): Started chili2 resname6 (ocf::pacemaker:Dummy): Started chili2
and in fact when using crm to start /stop for example : crm resource start group-dummy1 (this one is instantaneously taken in account) then just after the first one, I do : crm resource start group-dummy2 there is a latency of 10 to 14 s before the resource is displayed "started" via crm_mon So that is the basic cause of my latency problem when I execute all the needed crm commands in my scripts to address many HA clusters from a central management node. I know that I can gather as much as possible crm commands in a file on remote node and ask crm to take the file as input, but within my scripts, I can't do that for all crm commands, so would it be possible to reduce these 10 to 14s via a pacemaker parameter tuning ?
