[RFE] improve `openstack undercloud upgrade' rollback capabilities

[Cédric Jeanneret deactivated]

Dear Stackers,

The following command should do a dump of all mysql database prior anything: `openstack undercloud upgrade'

This would allow anyone to do a clean rollback of an upgrade.

In addition, it would be great if that same command could in some way do a backup of the /usr/share/openstack-tripleo-heat-templates content.

Small idea with the latter: in our env, we actually copied the whole directory somewhere else in order to manage its content with git, outside of yum managed contents.
We hence have a small update script that do all what's needed for us:
http://paste.openstack.org/show/623739/

This means, once the upgrade is over, we just have to do a "git commit --all" in the local template directory.
This, in addition to the mysql dump, would allow a clean rollback, even if the stack is broken (like we had just today).

Care to check that feature request? :).

Thank you!

Cheers,

C.

This RFE has been solved by the Backup and restore procedure AFAIK.
I think we can close it.

Hi,

Creating a backup and doing the Undercloud upgrade are 2 totally different things,

Before doing the upgrade, run: openstack undercloud backup, make sure you have the assets you need, and run the openstack undercloud upgrade steps.
