[ovirt-users] Deployment issues

Hello all, last September I deployed Ovirt on a CentOS 8 server, with storage on our gluster (replica 3). I then added some VMs, etc. A few days ago I managed to screw everything up and, after bannging my head for a couple of days, decided to start from scratch. I made a copy of all the data under the storage to a safe space, the ran ovirt-hosted-engine-cleanup and deleted everything under the storage and tried to create a new hosted engine (I tried both from the cockpit and from command line). Everything seems to work fine (I can ssh to the engine) until it tries to save the engine to storage and it fails with the error: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Error creating a storage domain's metadata]\". HTTP response code is 400."} I don't get any more details. I'm using exactly the same parameters I used before. I have no problems reaching the gluster storage and the process does create the top-level directory and <top-level>/dom_md/ids with the correct ownership. I looked at the glusterfs log files, including the rhev-data-center-mnt-glusterSD-<host:_root>.log file, but I don't spot any specific error. What am I doing wrong ? Is there something else I need to clean up before trying a new deployment ? Should I just try to delete all of the ovirt configuration files ? Which ones ?
