Public bug reported: When installing and configuring nova with puppet-nova (with either tripleo, packstack or puppet-openstack-integration), we are getting following errors:
Debug: Executing: '/usr/bin/nova-manage cell_v2 simple_cell_setup --transport-url=rabbit://guest:guest@172.19.2.159:5672/?ssl=0' Debug: /Stage[main]/Nova::Db::Sync_cell_v2/Exec[nova-cell_v2-simple-cell-setup]/returns: Sleeping for 5 seconds between tries Notice: /Stage[main]/Nova::Db::Sync_cell_v2/Exec[nova-cell_v2-simple-cell-setup]/returns: Cell0 is already setup. Notice: /Stage[main]/Nova::Db::Sync_cell_v2/Exec[nova-cell_v2-simple-cell-setup]/returns: No hosts found to map to cell, exiting. The issue seems to be that it's running "nova-manage cell_v2 simple_cell_setup" as part of the nova database initialization when no compute nodes have been created but it returns 1 in that case [1]. However, note that the previous steps (Cell0 mapping and schema migration) were successfully run. I think for nova bootstrap a reasonable orchestrated workflow would be: 1. Create required databases (including the one for cell0). 2. Nova db sync 3. nova cell0 mapping and schema creation. 4. Adding compute nodes 5. mapping compute nodes (by running nova-manage cell_v2 discover_hosts) For step 3 we'd need to get simple_cell_setup to return 0 when not having compute nodes, or having a different command. With current behavior of nova-manage the only working workflow we can do is: 1. Create required databases (including the one for cell0). 2. Nova db sync 3. Adding all compute nodes 4. nova cell0 mapping and schema creation with "nova-manage cell_v2 simple_cell_setup". Am I right?, Is there any better alternative?
