This bug blocks the CinderLib integration on RHVH in both 4.3 and 4.4.

I started to test the Migration path from 4.3 -> 4.4 on RHVH which includes:
* 4.3 RHVH CinderLib integration  => this is the current phase where the test blocked by the issue in the description below.
* 4.3 Engine-backup (4.3) including CinderLib data/SDs/VMs/Disk 
* Reprovision RHVH to 4.4
* 4.4 Engine restore 
* 4.4 Check all CinderLib data/SD's/VMs/Disks are there fully functional.

The hosted-engine-setup should add the option to activate CinderLib in RHVH (as in RHEL) in order to complete the test.

It doesn’t block anything. It only makes automation a little bit different because you have to reconfigure it later. 
We can defer it u til we decide to enable cinderlib by default

Didi this looks like a backup / restore issue, can you please have a look?

Can you please clarify what the problem is, exactly? Thanks.

In which version? Before upgrade? After upgrade?

Ok, but what's next? Is the above line in itself a problem? Did engine-setup fail? Please clarify.

Also: Please note that engine-setup (or the relevant packages' dependencies/requirements) specifically do not handle _installing_ cinderlib. You have to do this yourself. But I do not think this should affect engine-setup - it should still create db/user etc. if you reply Yes.

> There is nothing about CinderLib in ovirt-ansible-hosted-engine-setup .

If you mean "in its code", you are right, but I am not sure why this is a problem.
If you search, you'll also not find there any mention of e.g. websocket-proxy, but it's still working.

You mean, after you run above engine-setup? Sounds like a bug. Please attach setup log. Thanks!

You mean, that you want support in the software for doing:
1. Install 4.3 hosted-engine without cinderlib
2. Upgrade to 4.4 in a single "step", and have cinderlib
?

As Michal noted, I do not think we'll do this before it's out of "Tech Preview", but this is mainly a question for PM - it's an RFE, anyway, not a bug.

Without fixing this, all you really want is reasonable procedures to:

1. Install and setup with cinderlib in 4.3, upgrade to 4.4 and keep cinderlib working
2. Install 4.3 without cinderlib, upgrade to 4.4, add cinderlib

Am I missing something? Is any of these problematic?

Thanks!

Above has:

2020-08-31 01:30:56,629+0300 ERROR otopi.plugins.ovirt_engine_common.ovirt_engine.system.he he._validate:114 It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode.
In that case you should put the system into the "Global Maintenance" mode before running engine-setup, or the hosted-engine HA agent might kill the machine, which might corrupt your data.

Did you set global maintenance mode?

Verified 

After set to global maintenance mode, it looks better, the Setup Cinderlib integration is True and the Configure local CinderLib database is True too.

The engine-setup --reconfigure-optional-components" command still failed although the configuration of CinderLib database to true
Moreover, the CinderLib integration flow completed successfully but it still impossible to add a new MBD via REST API and failed on CinderLib DB required.
