The famous error message is "Can't DROP
'ixu_user_name_domain_id'; check
that column/key exists") [SQL: u'ALTER TABLE user DROP INDEX
ixu_user_name_domain_id']", which was reported by someone else as a bug
https://bugs.launchpad.net/keystone/+bug/1572341. This bug was fixed on July
7, 2016 which is after the rdo release.
This fix is included in Keystone 9.1.0, I've built it now, until it
reaches repositories you can take it from Koji:
http://cbs.centos.org/koji/buildinfo?buildID=11451
We're working on automated Koji builds triggered by upstream release
tags, for now it's a manual action.
I am wondering if it is possible to have a new rdo-release for Mitaka
to
include these bug fixes, otherwise, the existing production Keystone
database couldn't be migrated without great pain.
Please note that since Liberty there aren't coordinated upstream
stable point releases, it is up to each project to releases
asynchronously[1].
Cheers,
Alan
