sean-k-mooneylyarwood: related to ^ i was thinking that maybe we coudl extend hard reboot to fix some issue if we can detect them12:03
sean-k-mooneynormally hard reboot does nto talk to neutron to bind port and in general i think that shoudl continue to be the case. but what i was thinking is maybe we should check the host in the network info cache if its set and fix the port binding maybe do the same for volumes?12:04
sean-k-mooneyi didnt put that in that patch intentionally to keep it small but do you think somehting like that would make sense12:04

MrClayPoleHi, We have 2 nova compute nodes that each have 2 x 10 Gbit iSER network adaptors. They connect to Zadara SAN's clustered IP address. This works but we would like to enable multipath but we are unsure how to configure cinder/nova/iscsiadm to achieve this.16:18
*** sapd1_x has joined #openstack-nova16:19
*** ociuhandu has joined #openstack-nova16:24
sean-k-mooneythats funny someone asked us about how to turn off multipathd a few days ago since they were not using it in there setup.16:26
sean-k-mooneyi think nova actully does not care about multipathd and that is actully handeled in os-brick16:27
sean-k-mooneylyarwood: is that way of base or is this actully handeled in os-brick ^16:27

*** LinPeiWen7 has quit IRC16:28
sean-k-mooneyMrClayPole: im not familar with zadara but i assume you are connecint over iscsi16:31
*** links has quit IRC16:32
MrClayPolesean-k-mooney: yeah, we are experimenting in a test environment, we are using iSCSi iSER. I had a feeling it would be a cinder question but just wanted to check here first to make sure.16:33

sean-k-mooneyMrClayPole: well assuming your using libvirt drvier i think you jsut have to configure multipathd on the host then set https://docs.openstack.org/nova/latest/configuration/config.html#libvirt.volume_use_multipath to true16:35

sean-k-mooneyMrClayPole: if you are using a stanard deployment tool they likely have docs for it too16:41
MrClayPoleWe are running openstack ansible rocky. We've tried volume_use_multipath in nova.conf but we still see only a single connection in iscsiadm -m session and nothing under /dev/mapper16:54
sean-k-mooneyi assume you have installed multipathd and restarted the nova-compute agent then booted a new vm.16:55
sean-k-mooneywe wont automatically reconfigure existing vms so you will need a hard reboot to have the change take effect in addtion to the agent restart16:56
sean-k-mooneyi belive lyarwood privly suggested that doing a full host reboot was a cleaner approch as os-brick might be caching this somewhere not sure really.16:57
MrClayPoleYes, done a full compute host reboot as well as power down and back on an existing VM.17:00

sean-k-mooneyMrClayPole: yes qemus native supprot for isci does not support multipath17:04
sean-k-mooneyMrClayPole: the ablity to confgure that was unitentionally removed form nova17:05
sean-k-mooneyit was a few releases before someone noiced and now we only host mount i think17:05
