錯誤: Build of instance e2c92441-c02f-49f1-ac40-693763fc532c aborted: Volume 5f7fbb11-9627-4f9c-8f8f-3c55c8c996b0 did not finish being created even after we waited 0 seconds or 1 attempts. And its status is error.].
刪除不可用的存儲節點後解決
3.報錯信息：
查看nova-scheduler.log日誌 default default] No compute service record found for host openstack-2
解決方法：查詢nova數據庫，找到compute_nodes表項，刪除host爲openstack-2的節點，刪除方法delete from compute_nodes where host = “openstack-2”
