I wish to enable multipath storage access on the compute nodes. i have running instances on the compute nodes already. I need to change nova.conf on the compute nodes for this value:

iscsi_use_multipath = True

Actually this config item is changed to the following:


And then I need to restart nova-compute service

systemctl restart openstack-nova-compute.service

Now can this be done safely with running instances? Or do I need to live migrate or shutdown instances first before running this restart?

If its production ,would suggest to shutdown instances ,enable multipathing (make configuration changes accordingly ),restart cinder and nova services
