[ironic] Using ironic in a devstack environment to deploy OS on bare-metal host.
I met some problem when using ironic in a devstack environment to deploy OS on bare-metal host.
By now I can successfully boot into the tiny os and set ip, also I can ping the ip from my devstack server. However, when the tiny os running some configuration, it will failed after about 5 minutes.
I found some log information in "/var/log/ironic-python-agent.log" in the tiny os that may relate to the problem:
"DEBUG oslo_concurrency.processutils [-] u'iscsistart -f' failed. Not Retrying. execute /usr/local/lib/python2.7/site-packages/oslo_concurrency/processutils.py:457"
"DEBUG root [-] No iscsi connection detected. Skipping iscsi. Error: [Errno 2] No such file or directory _check_for_iscsi /usr/local/lib/python2.7/site-packages/ironic_python_agent/hardware.py:107"
"WARNING root [-] The root device was not detected in 27 seconds: DeviceNotFound: Error finding the disk or partition device to deploy the image onto: No suitable device was found for deployment - root device hints were not provided and all found block devices are smaller than 4294967296B."
"WARNING root [-] Can't find field vendor for device usb0 in device class net: IOError: [Errno 2] No such file or directory: '/sys/class/net/usb0/device/vendor'"
"WARNING root [-] Can't find field vendor for device tunl0 in device class net: IOError: [Errno 2] No such file or directory: '/sys/class/net/tunl0/device/vendor'"
"DEBUG root [-] No Mellanox devices found evaluate_hardware_support /usr/local/lib/python2.7/site-packages/ironic_python_agent/hardware_managers/mlnx.py:84"
And when it deploy faild and I run command "openstack baremetal node show server-51", it will show following information on 'last_error' field:
"Asynchronous exception: Node failed to deploy. Exception: Connection to agent failed: Failed to connect to the agent running on node f8794658-bc69-40cb-9673-be75f78ced21 for invoking command iscsi.start_iscsi_target. Error: ('Connection aborted.', BadStatusLine("''",)) for node"
I'm trying to debug, but have not find the root cause, please give me your advice if someone have experience on it. Thank you!
