Public bug reported: The `get_minimum_version_all_cells" function currently checks cell0 too. This will fail on a cell conductor when using templated cell uris as it will attempt to connect to the wrong database server.
For example set cell0 db uri as follows: [nova@cell1-controller-0 /]$ nova-manage cell_v2 update_cell --cell_uuid 00000000-0000-0000-0000-000000000000 --database_connection='{scheme}://{username}:{password}@{hostname}/?{query}' --transport-url='none:///' [nova@cell1-controller-0 /]$ nova-manage cell_v2 list_cells +---------+--------------------------------------+-----------------------------------------------------------------------------+--------------------------------------------------------------------------------------------------------------------------------------+----------+ | Name | UUID | Transport URL | Database Connection | Disabled | +---------+--------------------------------------+-----------------------------------------------------------------------------+--------------------------------------------------------------------------------------------------------------------------------------+----------+ | cell0 | 00000000-0000-0000-0000-000000000000 | none:/ | mysql+pymysql://nova:****@cell1.internalapi.redhat.local/?read_default_file=/etc/my.cnf.d/tripleo.cnf&read_default_group=tripleo | False | | cell1 | 9f8cc7bb-08f2-4658-a7e8-ece2b84c5e5c | rabbit://guest:****@cell1-controller-0.internalapi.redhat.local:5672/?ssl=1 | mysql+pymysql://nova:****@cell1.internalapi.redhat.local/nova?read_default_file=/etc/my.cnf.d/tripleo.cnf&read_default_group=tripleo | False | | default | abb3a2d8-cdee-4e0e-a6c2-1cf3b9c098de | rabbit://guest:****@cell1-controller-0.internalapi.redhat.local:5672/?ssl=1 | mysql+pymysql://nova:****@cell1.internalapi.redhat.local/nova?read_default_file=/etc/my.cnf.d/tripleo.cnf&read_default_group=tripleo | False | +---------+--------------------------------------+-----------------------------------------------------------------------------+--------------------------------------------------------------------------------------------------------------------------------------+----------+ The resulting cell0 database uri is incorrect as it using the cell1 database hostname from the cell conductor nova.conf. This should be nothing more than a cosmetic issue since the cell conductor should not connect to cell0, however it currently does in the minimum version check. Can be reproduced by running an upgrade check on a cell specific nova- conductor as this includes a min version check. ** Affects: nova Importance: Undecided Status: New ** Tags: cells ** Attachment added: "upgrade_check.txt" https://bugs.launchpad.net/bugs/1983044/+attachment/5605773/+files/upgrade_check.txt -- You received this bug notification because you are a member of Yahoo!
