Hi Luciano, I suggest you to check log files which usually provide a goof indication of what is going on.... usually.... You want to check the engine logs (ssh into your hosted engine, then /var/log/ovirt-engine) and vdsm logs on your hosts (/var/log/vdsm/vdsm.log) You want also to check if you multipath is updated and ok (multipath -ll or lsscsi) Cheers AG

I'm running oVirt 3.5, and recently had an issue with a split brain situation in the hosted engine's image. After solving that, I got the engine up an running, but something went wrong with my main storage. I have a datacenter with main storage being ISCSI, called vms-main-storage. This storagedomain is marked as inactive. The only action I can attemp to do to it is activate it. But it won't. It just fails and no reason is given in the web ui. I also tried activating it through the cli, and result is status 400, reason bad request, detail internal engine error. Strange thing is that VM's are still running with their images in this storage and they are running with no problem at all! How can I have this storagedomain again in a healthy state??? Thanks! -- Luciano Natale
