Not sure I get your problem. Microversion 2.14 specifically removed onSharedStorage flag, but previous versions were having it mandatory on the API : https://github.com/openstack/nova/commit/c01d16e8
Novaclient was defaulting the onSharedStorage to False previously (see https://github.com/openstack/python-novaclient/commit/5a3956c3 ) which meant that you needed to correctly provide the right flag value. You say "if we didn't pass this argument, we will pass the False value": sure, that's what is attended for versions older than 2.14, so what's the problem ? Just in case you have shared storage and microversion older than 2.14, then you need to evacuate that way : nova evacuate --on-shared-storage true Closing the bug but feel free to reopen it if you consider I misunderstood the problem and then please explain it differently then. ** Changed in: nova Status: New => Invalid -- You received this bug notification because you are a member of Yahoo!
