Previously, we would use the\n\u0027drop_move_claim_at_destination\u0027 RPC call to (surprise!) drop the move\nclaim at the destination host, and would then update the instance and\nmigration records on the source host. For this reason, the call to\n\u0027drop_move_claim_at_destination\u0027 was a call rather than a cast to\nprevent races between this dropping of the move claim at the destination\nand the updating of the instance and migration records, since the latter\nstep destroyed some information required by the former.\n\nWe\u0027re changing this now to do both the dropping of the move claim and\nthe updating of the instance and migration records on the destination\nhost. This obviates the need for a call instead of a cast, so we switch\nthis too. We must continue to update the instance and migration records\non the source host for now, since we can\u0027t be sure the destination\nsupports this RPC version, but that will change once we bump the RPC\nversion in the future.\n\nWIP because this clearly isn\u0027t working yet. Need to figure out why the\nhost_a pinning information is getting out of sync.\n\nChange-Id: Iddbaaedb320750c14a8c767edbf01fadd20d480d\nSigned-off-by: Stephen Finucane \u003cstephenfin@redhat.com\u003e\n","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/695d80e898d799b5eb155787630ba90640d6b540"}],"resolve_conflicts_web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/695d80e898d799b5eb155787630ba90640d6b540"}]},"branch":"refs/heads/master"}},"requirements":[],"submit_records":[],"submit_requirements":[]}
