Check NixOS configurations / eval-hosts (push) Successful in 10m26s
acceptance-tests.sh: replace drbdadm-role-based Active node detection with crm_mon-based detection. DRBD role briefly reads Secondary during Pacemaker transitions, causing T2/T3/T4 to target the wrong node. crm_mon Promoted:/ Masters: lines are authoritative; wait up to 90 s for Pacemaker to settle before falling back to NODE1. cluster-init.sh: add crm_resource --cleanup before the VIP wait loop so stale migration-threshold failure counters from previous cluster-init runs are cleared before Pacemaker decides resource placement.
