Jul 1, 2025July 2025 monthly summary for rackerlabs/genestack focusing on OpenStack storage node reliability and maintainability. Deliverables centered on refining multipath and iSCSI initialization to prevent storage access conflicts and to improve uptime for OpenStack-backed workloads. Key actions include disabling multipath on block nodes while enabling iscsid, updating documentation to clarify the custom_multipath scope, and introducing an automation task to install open-iscsi on block nodes to ensure correct storage node access and prevent iSCSI initiator conflicts. A targeted commit fixed the behavior: 'Fix: Ensure multipath disabled on block nodes. Only enable iscsid (#1078)'.
