When you ran `engine-setup` did you enable cinderlib preview (it will not be enabled by default)? It should handle the creation of the database automatically, if you didn't you can enable it by running: `engine-setup --reconfigure-optional-components` On Wed, Sep 30, 2020 at 1:58 AM Michael Thomas <wart@caltech.edu> wrote:
Hi Benny,
Thanks for the confirmation. I've installed openstack-ussuri and ceph Octopus. Then I tried using these instructions, as well as the deep dive that Eyal has posted at https://www.youtube.com/watch?v=F3JttBkjsX8.
I've done this a couple of times, and each time the engine fails when I try to add the new managed block storage domain. The error on the screen indicates that it can't connect to the cinder database. The error in the engine log is:
2020-09-29 17:02:11,859-05 WARN [org.ovirt.engine.core.bll.storage.domain.AddManagedBlockStorageDomainCommand] (default task-2) [d519088c-7956-4078-b5cf-156e5b3f1e59] Validation of action 'AddManagedBlockStorageDomain' failed for user admin@internal-authz. Reasons: VAR__TYPE__STORAGE__DOMAIN,VAR__ACTION__ADD,ACTION_TYPE_FAILED_CINDERLIB_DATA_BASE_REQUIRED,ACTION_TYPE_FAILED_CINDERLIB_DATA_BASE_REQUIRED
I had created the db on the engine with this command:
su - postgres -c "psql -d template1 -c \"create database cinder owner engine template template0 encoding 'UTF8' lc_collate 'en_US.UTF-8' lc_ctype 'en_US.UTF-8';\""
...and added the following to the end of /var/lib/pgsql/data/pg_hba.conf:
host cinder engine ::0/0 md5 host cinder engine 0.0.0.0/0 md5
Is there anywhere else I should look to find out what may have gone wrong?

The feature is currently in tech preview, but it's being worked on. The feature page is outdated, but I believe this is what most users in the mailing list were using. We held off on updating it because the installation instructions have been a moving target, but it is more stable now and I will update it soon.
Specifically speaking, the openstack version should be updated to train (it is likely ussuri works fine too, but I haven't tried it) and cinderlib has an RPM now (python3-cinderlib)[1], so it can be installed instead of using pip, same goes for os-brick. The rest of the information is valid.

I'm looking for the latest documentation for setting up a Managed Block Device storage domain so that I can move some of my VM images to ceph rbd.
I found this:
https://ovirt.org/develop/release-management/features/storage/cinderlib-inte...
...but it has a big note at the top that it is "...not user documentation and should not be treated as such."
The oVirt administration guide[1] does not talk about managed block devices.
I've found a few mailing list threads that discuss people setting up a Managed Block Device with ceph, but didn't see any links to documentation steps that folks were following.
Is the Managed Block Storage domain a supported feature in oVirt 4.4.2, and if so, where is the documentation for using it?
