lrmd (the local resource manager) won't run more than this number of resource operations in parallel. It's a mechanism to prevent placing too much load on the node. As soon as one of the operation finishes, the next one in the queue is started. > Is it possible to tune it ? > How can it be tuned ? with regard with which items ? nb of resources > configured ? anything else ? Yes, by setting LRMD_MAX_CHILDREN in /etc/sysconfig/pacemaker in SUSE distributions (SLES or OpenSUSE). Don't know if init scripts of other distributions have this option. I think you'll need the latest Heartbeat (if you're running heartbeat and not corosync). Note that this is a per-node setting.
