Hello, As another person has mentioned (Chanu Romain), I am attempting an upgrade from Queens to Train. I have successfully upgraded Keystone and Glance, but while trying to separate Placement's databases out from Nova, I run into the the same issue with placement-status upgrade check: # placement-status upgrade check +-----------------------------------------------------------------+ | Upgrade Check Results | +-----------------------------------------------------------------+ | Check: Missing Root Provider IDs | | Result: Success | | Details: None | +-----------------------------------------------------------------+ | Check: Incomplete Consumers | | Result: Warning | | Details: There are -3511 incomplete consumers table records for | | existing allocations. Run the "placement-manage db | | online_data_migrations" command. | +-----------------------------------------------------------------+ Likewise, running placement-manage db online_data_migrations does nothing. I am running this placement migration on a dev cluster which has had the databases from a Prod cluster restored to it. This has worked well for me previously as a way to run through upgrades without touching the live system. Thanks very much, Seth
