[ovirt-users] Adding another host to my cluster

Mon May 16 17:59:16 UTC 2016

Roy,

Thank you so much for asking for the logs on the engine. The serial.txt bein blank was my issue. I found a solution in the following thread online here: http://lists.ovirt.org/pipermail/users/2014-November/028870.html
I did the exact same thing that Dinuwan did to solve his issue back in 2014 and was able to enrol my new server and install the hosted-engine just fine on it.

I am not certain what caused serial.txt to be empty and am will to share logs to anyone from the oVirt team who might want to see them. For my purposes, I'm considering this issue solved.

Thanks to everyone who offered advice and suggestions.

Cheers,
Gervais

Also, the engine machine has the install log - open one of the Event logs in the UI that says you host installation failed and you will see it retrieved the install log to a path under your engine. Please include this as well.
