I've run into the following issue with oVirt node on a single host using the
single node hyperconverged wizard:

The only non-default settings I changed were the stripe size and number of

Any ideas to work around this? I will be deploying to 6 nodes eventually but
wanted to try out the engine before the rest of my hardware arrives :)
