[ovirt-users] Re: Latest ManagedBlockDevice documentation

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? --Mike On 9/29/20 3:34 PM, Benny Zlotnik wrote: > 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 The feature page is outdated, but I believe this is what most users 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.
