Title:
boot from fcsan volume live migration caused bdm table lost
connection_info value
Status in OpenStack Compute (Nova):
Confirmed
Status in Volume discovery and local storage management lib:
Confirmed
Bug description:
this issue reproduce steps:
1. nova boot vm1 base fcsan volume, this instance bdm table connection_info
as following:
{"driver_volume_type": "fibre_channel", "serial":
"63013f85-34fd-4040-a234-6ee57e1a8eeb", "data": {"device_path": "/dev/dm-11",
"target_discovered": false, "devices": [{"device": "/dev/sdv", "host": "7",
"id": "0", "channel": "0", "lun": "8"}, {"device": "/dev/sdx", "host": "8",
"id": "0", "channel": "0", "lun": "8"}], "qos_specs": null, "volume_id":
"63013f85-34fd-4040-a234-6ee57e1a8eeb", "target_lun": 8, "access_mode": "rw",
"target_wwn": ["20014c09b4b04d0e", "20024c09b4b04d0e", "20034c09b4b04d0e",
"20044c09b4b04d0e", "20014c09b4b04d18", "20024c09b4b04d18", "20034c09b4b04d18",
"20044c09b4b04d18"], "multipath_id": "3500422790776c4d6"}}
2. run nova live-migration vm1 fininshed, vm1 was migrated another host, but
this instance bdm table connection_info as following:
{"driver_volume_type": "fibre_channel", "serial":
"63013f85-34fd-4040-a234-6ee57e1a8eeb", "data": { "target_discovered": false,
"qos_specs": null, "volume_id": "63013f85-34fd-4040-a234-6ee57e1a8eeb",
"target_lun": 9, "access_mode": "rw", "target_wwn": ["20014c09b4b04d0e",
"20024c09b4b04d0e", "20034c09b4b04d0e", "20044c09b4b04d0e", "20014c09b4b04d18",
"20024c09b4b04d18", "20034c09b4b04d18", "20044c09b4b04d18"], "multipath_id":
"3500422790776c4d6"}}
we can find the key "device_path" and "devices" was lost
3.if we live-migration this vm1 again,will fail . Call chain are as follows:
