I hadn't installed the necessary packages when the engine was first
installed.
However, running 'engine-setup --reconfigure-optional-components'
doesn't work at the moment because (by design) my engine does not have a
network route outside of the cluster. It fails with:
[ INFO ] DNF Errors during downloading metadata for repository 'AppStream':
- Curl error (7): Couldn't connect to server for
http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=AppStream&infra=$infra
[Failed to connect to mirrorlist.centos.org port 80: Network is unreachable]
[ ERROR ] DNF Failed to download metadata for repo 'AppStream': Cannot

for
http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=AppStream&infra=$infra
[Failed to connect to mirrorlist.centos.org port 80: Network is unreachable]
I have a proxy set in the engine's /etc/dnf/dnf.conf, but it doesn't
seem to be obeyed when running engine-setup. Is there another way that
I can get engine-setup to use a proxy?

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`

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

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The feature page is outdated, but I believe this is what most users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-integration.html
...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?
