Hi, Fred. I'm using release 4.0.5. I made a fresh redeploy today and reproduced the issue. I'm attaching engine and vdsm log file, the time to look is around 12:15:13 Also, when I try to delete storage domain from engine - it also returns error, so, this domain seems to be stuck in configuration (it is also displayed at the end of engine log) Appreciate any comments. Sergei.
