I ran 'hosted-engine --vm-start' after trying to ping the engine and running 'hosted-engine --vm-status' (which said it wasn't running) and it reported that it was 'destroying storage' and starting the engine, though it did not start it. I could not see any evidence from 'hosted-engine --vm-status' or logs that it started. By this point I was in a panic to get VMs running. So I had to fire up the old bare metal engine. This has been a very disappointing experience. I still have no idea why the IDs in 'host_id' differed from the spm ID, and why, when I put the cluster into global maintenance and shutdown all the hosts, the Hosted Engine did not come up, nor any of the VMs. I don't feel confident in this any more. If I try the deploying the Hosted Engine again I am not sure if it will result in the same non-functional cluster. It gave no error on deployment, but clearly something was wrong.
I have two questions: 1. Why did the VMs (apart from the Hosted Engine VM) not start on power up of the hosts? Is it because the hosts were powered down, that they stay in a down state on power up of the host? 2. Now that I have connected the bare metal engine back to the cluster, is there a way back, or do I have to start from scratch again? I imagine there is no way of getting the Hosted Engine running again. If not, what do I need to 'clean' all the hosts of the remnants of the failed deployment? I can of course reinitialise the LUN that the Hosted Engine was on - anything else?
