Re: [ClusterLabs] Dependency loop
Hello Ken, here is the output of my other 2 clusters. *cluster 0:* Location Constraints: Ordering Constraints: Colocation Constraints: virtual_ip with vg1 (score:INFINITY) virtual_ip with lv1 (score:INFINITY) virtual_ip with nfs-daemon (score:INFINITY) virtual_ip with lv1_export (score:INFINITY) virtual_ip with samba (score:INFINITY) virtual_ip with lv1_export_squash (score:INFINITY) Ticket Constraints: *and cluster 2:* Location Constraints: Ordering Constraints: Colocation Constraints: lvm_scratch with cluster2_vip (score:INFINITY) lun_scratch with cluster2_vip (score:INFINITY) lvm_user_dirs with cluster2_vip (score:INFINITY) lun_user_dirs with cluster2_vip (score:INFINITY) lvm_user_dirs-bak with cluster2_vip (score:INFINITY) nfsserver with cluster2_vip (score:INFINITY) scratch-export-squash with cluster2_vip (score:INFINITY) scratch-export-nosquash with cluster2_vip (score:INFINITY) scratch-export-nosquash-linfarm with cluster2_vip (score:INFINITY) scratch-export-nosquash-atlas with cluster2_vip (score:INFINITY) user_dirs-export-squash with cluster2_vip (score:INFINITY) user_dirs-export-nosquash with cluster2_vip (score:INFINITY) user_dirs-export-nosquash-linfarm with cluster2_vip (score:INFINITY) user_dirs-export-nosquash-atlas with cluster2_vip (score:INFINITY) samba with cluster2_vip (score:INFINITY) lvm_scratch_bak_btrfs with cluster2_vip (score:INFINITY) As you can see, the output of cluster 0 is similar with cluster 1 but there are no messages for dependency loop. Shouldn't I have these errors on cluster 0 too? Is cluster 2 output the one that you would recognize as correct? Also, do you believe that these errors could be the source of the problem, that my resources return to the failed node, after it has resumed operation and do not stay on the one that took control of the resources after the failure? Thanks for your time, George.

[ClusterLabs] Dependency loop
Hi, my logs keep being flooded by "Breaking dependency loop at " but I cannot figure out why. I haven't spotted such a loop. redhat-release CENTOS 7.2.1511 pcs --version 0.9.143 Here's an excerpt from the logs: Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at lvm_titanas-bak Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at lvm_titanas-bak Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at lvm_titanas-bak Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Mar 16 07:29:54 [3670] filesrv12.localdomainpengine: info: rsc_merge_weights: lvm_data-bak: Breaking dependency loop at cluster1_vip Here's the output of "pcs constraint --full" Location Constraints: Ordering Constraints: Colocation Constraints: cluster1_vip with lvm_data (score:INFINITY) (id:colocation-cluster1_vip-lvm_data-INFINITY) cluster1_vip with lun_data (score:INFINITY) (id:colocation-cluster1_vip-lun_data-INFINITY) cluster1_vip with lvm_titanas (score:INFINITY) (id:colocation-cluster1_vip-lvm_titanas-INFINITY) cl
