Just created a test data center. Now, when I try to add/create a new storage domain there is V4 format for the existing domain and V5 for the new data center.

Hi Shani, thanks for your help. The master SD is the one the hosted engine is on. I can't put it to maintenance and attach it to another domain. But I`ll try this procedure with one of the oder SDs. If it works: is there a way to change the master domain to one of the others or is it always the one the hosted enginge is running on? Regards, Marcel

Hi Shani, in theory it's exactly you have quoted. In reality ... that's not what we all thought about :) I had issues with the master domain role. Djagoo, if you have issues - just poweroff and power on the engine. Upon 5-6th time it will decide to change it :)  Best Regards, Strahil Nikolov В неделя, 16 февруари 2020 г., 14:53:21 ч.

Taken from [1]: To change the Master Storage Domain to another specific Storage Domain, the below steps need to be followed: * Put all storage domains except the Master storage domain and the one that needs to be the new master storage to maintenance mode from Data Centre -> Lower Sub tab -> Storage -> Right-click -> Maintenance. (The only active storage domains now would be the Master storage domain and the storage domain which need to be the master.) *Now put the "Master storage" to maintenance mode. * The only active storage domain (which you want to make the new master storage) would automatically be the master storage.

I tried to implement gluster post install. For me it was a disaster. I rebuilt the engine host and deployed without gluster. I will try it in the future but it will be a ground up deployment. I f you disable gluster and the update the cluster again with all hosts, it may come back to life. I spent hours trying to get it to work.

The newly created storage domain has version 5 (default since compatibility level 4.3 according to documentation). Hosted engine version is 4.3.8.2-1.el7 All hosts are updated to the latest versions and are rebooted. Cluster and DataCenter compatibility version is 4.3. Master data domain and all other domains are Format V4 and there is no V5 available in dropdown menus. Even if I try to create a new storage domain from manager there is only V4 available. The system and all hosts where installed march 2019 so it was ovirt release 4.3.2 or 4.3.1 which created the existing domains. Is there a way to update the master storage domain to V5? It seems I cannot downgrade the datacenter to compat 4.2 and then raise it again. After two weeks I'm out of ideas. Can anyone help please?
