I didn't create them. Does the crm create constraints itself ? location cli-ban-prim_vm_mausdb-on-ha-idg-2 prim_vm_mausdb role=Started -inf: ha-idg-2 location cli-prefer-prim_vm_mausdb prim_vm_mausdb role=Started inf: ha-idg-2 One location constraint inf, one -inf for the same resource on the same node. Isn't that senseless ? "crm resorce scores" show -inf for that resource on that node: native_color: prim_vm_mausdb allocation score on ha-idg-1: 100 native_color: prim_vm_mausdb allocation score on ha-idg-2: -INFINITY Is -inf stronger ? Is it true that only the values for "native_color" are notable ? A principle question: When i have trouble to start/stop/migrate resources, is it senseful to do a "crm resource cleanup" before trying again ? (Beneath finding the reason for the trouble). Sorry for asking basic stuff. I read a lot before, but in practise it's total different. Although i just have a vm as a resource, and i'm only testing, i'm sometimes astonished about the complexity of a simple two node cluster: scores, failcounts, constraints, default values for a lot of variables ... you have to keep an eye on a lot of stuff.
