Subject [DISCUSS] DB upgrade issue workaround for 4.10.0.0 users upgrading to 4.11.0.0
Date Mon, 12 Feb 2018 13:29:18 GMT
All,


Some of us have discussed and found an upgrade path issue that only affects the 4.10.0.0 users
who may see missing columns in certain tables post upgrading to 4.11.0.0 version.


The issue is/was that at the time 4.10.0.0 was released, PRs were merged to the 'then' master
branch that made changes to the 4.9.3.0->4.10.0.0 upgrade path instead of the 4.10.0.0->4.11.0.0
upgrade path. One of such change was an ALTER statement that added a new column `service_package_id`,
and if 4.10.0.0 version is upgraded to 4.11.0.0 such environments may report sql related errors
related to this column.


(My colleagues Bobby and Ernie may chip in their findings and test results as well)


Pull request: https://github.com/apache/cloudstack/pull/2452

Jira ticket: https://issues.apache.org/jira/browse/CLOUDSTACK-10285


The proposed workaround is to move the changes to the expected upgrade path of 4.10.0.0->4.11.0.0.
This is *not ideal* given 4.11.0.0 is released but at least 4.10.0.0 users who may want to
upgrade to 4.11.1.0 or later won't face the issue.


The proposed workaround for current 4.10.0.0 users who may want to upgrade to 4.11.0.0 is
to run the following sql statements from the PR above before upgrading to 4.11.0.0: (we may
discuss and update the release notes website as well)

            left join
        `cloud`.`async_job` ON async_job.instance_id = user.id
            and async_job.instance_type = 'User'
            and async_job.job_status = 0;


### end sql ###


Thoughts, perhaps other ways to tackle this?
