Comment 6 for bug 1661772

This is unfortunately a known issue in nova for several years now, as nova historically has not had proper support for shared storage (there are many gaps).

We had the same issue for boot-from-volume servers until recently [1] and there's a bug open related to it [2].

For shared storage support, we have been working on it but making slow progress. You can find some information about it in this bug: https://bugs.launchpad.net/nova/+bug/1784020 and on our Stein PTG etherpad at L219: https://etherpad.openstack.org/p/nova-ptg-stein

Because of higher priority work happening this cycle and the fact that this issue is latent, I'm going to set this bug to Medium importance.
