Re: [ovirt-users] Hosted Engine-Setup issue additional host

The situation is clear though: Broker dies when it tries to initialize logging (missing /dev/stdout ???) Agent dies because it can't connect to the broker. My /dev/stdout looks like this: lrwxrwxrwx. 1 root root 15 Mar 30 17:29 /dev/stdout -> /proc/self/fd/1 And /proc/self/fd/1 is obviously related to the process. But I have an idea. Can you check whether the /proc/self/fd/1 is there? It might be missing if the broker closed its stdout during daemonizing.
