Hi! After having found showscores.sh, I thought I can improve the perfomance by porting it to Perl, but it seems the slow part actually is calling pacemakers helper scripts like crm_attribute, crm_failcount, etc...
But anyway: Being quite confident what my program produces (;-)), I found some odd score values for clones that run in a two node cluster. For example: Resource Node Score Stickin. Fail Count Migr. Thr. ---------------------- ---- --------- -------- ---------- ---------- prm_DLM:1 h02 1 0 0 0 prm_DLM:1 h06 0 0 0 0 prm_DLM:0 h02 -INFINITY 0 0 0 prm_DLM:0 h06 1 0 0 0 prm_O2CB:1 h02 1 0 0 0 prm_O2CB:1 h06 -INFINITY 0 0 0 prm_O2CB:0 h02 -INFINITY 0 0 0 prm_O2CB:0 h06 1 0 0 0 prm_cfs_locks:0 h02 -INFINITY 0 0 0 prm_cfs_locks:0 h06 1 0 0 0 prm_cfs_locks:1 h02 1 0 0 0 prm_cfs_locks:1 h06 -INFINITY 0 0 0 prm_s02_ctdb:0 h02 -INFINITY 0 0 0 prm_s02_ctdb:0 h06 1 0 0 0 prm_s02_ctdb:1 h02 1 0 0 0 prm_s02_ctdb:1 h06 -INFINITY 0 0 0 For prm_DLM:1 for example one node has score 0, the other node has score 1, but for prm:DLM:0 the host that has 1 for prm_DLM:1 has -INFINITY (not 0), while the other host has the usual 1. So I guess that even without -INFINITY the configuration would be stable. For prm_O2CB two nodes have -INFINITY as score. For prm_cfs_locks the pattern is as usual, and for rpm_s02_ctdb to nodes have -INFINITY again. I don't understand where those -INFINITY scores come from. Pacemaker is SLES11 SP4 (1.1.12-f47ea56). It might also be a bug, because when I look at a three-node cluster, I see that a ":0" resource had score 1 once, and 0 twice, but the corrsponding ":2" resource has scores 0, 1, and -INFINITY, and the ":1" resource has score 1 once and -INFINITY twice. When I look at the "clone_solor" scores, the prm_DLM:* primitives look as expected (no -INFINITY). However the cln_DLM clones have score like 10000, 8200 and 2200 (depending on the node). Can someone explain, please?
