Jeff is right, it's a limitation of kernel rbd, the recommendation is to add `rbd default features = 3` to the configuration. I think there are plans to support rbd-nbd in cinderlib which would allow using additional features, but I'm not aware of anything concrete. Additionally, the path for the cinderlib log is /var/log/ovirt-engine/cinderlib/cinderlib.log, the error in this case would appear in the vdsm.log on the relevant host, and would look something like "RBD image feature set mismatch. You can disable features unsupported by the kernel with 'rbd feature disable'" On Wed, Oct 14, 2020 at 12:01 AM Michael Thomas <wart@caltech.edu> wrote:
After getting past the proxy issue, I was finally able to run the engine-setup --reconfigure-optional-components. The new ManagedBlockStorage storage domain exists, and I was able to create a disk. However, I am unable to attach the disk to a running VM.
The engine.log shows the following, with a reference to a possible cinderlib error ("cinderlib execution failed"):

The /var/log/cinder/ directory on the ovirt node is empty, and doesn't exist on the engine itself.
To verify that it's not a cephx permission issue, I tried accessing the block storage from both the engine and the ovirt node using the credentials I set up in the ManagedBlockStorage setup page:
[root@ovirt4]# rbd --id ovirt ls rbd.ovirt.data volume-5419640e-445f-4b3f-a29d-b316ad031b7a [root@ovirt4]# rbd --id ovirt info rbd.ovirt.data/volume-5419640e-445f-4b3f-a29d-b316ad031b7a rbd image 'volume-5419640e-445f-4b3f-a29d-b316ad031b7a': size 100 GiB in 25600 objects order 22 (4 MiB objects) snapshot_count: 0 id: 68a7cd6aeb3924 block_name_prefix: rbd_data.68a7cd6aeb3924 format: 2 features: layering, exclusive-lock, object-map, fast-diff, deep-flatten op_features: flags: create_timestamp: Tue Oct 13 06:53:55 2020 access_timestamp: Tue Oct 13 06:53:55 2020 modify_timestamp: Tue Oct 13 06:53:55 2020
Where else can I look to see where it's failing?

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 [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?
