The "*_last_*" IDs simply refer to the last (= most recently executed) operation :) Those IDs are not directly used by the cluster; they're just used to store the most recent operation in the CIB. > Background: I wrote some program that extarcts the runtimes of operations > from the CIB, like this: > prm_r00_fs_last_0 13464 stop > prm_r00_fs_last_0 61 start > prm_r00_fs_monitor_300000 34 monitor > prm_r00_fs_monitor_300000 43 monitor > > The first word is the "id" attribute, the second is the "exec-time" > attribute, and the last one (added to help myself out of confusion) is the > "operation" attribute.

Is that intentional? Yes. The operation is queued when it is received, and if it has a start delay, a timer is set to execute it at a later time. So the delay happens while the operation is queued. > Another program tried to extract queue and execution times for operations, > and the sorted result looks like this then: > > 1 27 prm_nfs_home_exp_last_0 monitor > 1 39 prm_q10_ip_2_monitor_60000 monitor > 1 42 prm_e10_ip_2_monitor_60000 monitor > 1 58 prm_s01_ip_last_0 stop > 1 74 prm_nfs_cbw_trans_exp_last_0 start > 30001 1180 prm_stonith_sbd_monitor_180000 monitor > 30001 178 prm_c11_ascs_ers_monitor_60000 monitor > 30002 165 prm_c11_ascs_ers_monitor_45000 monitor > > Regards, > Ulrich _______________________________________________ Users mailing list: Users@clusterlabs.org http://clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
