I've just installed OMV (4.1.8.2-1) on a RockPro64. I finally got it running and seemingly robust. There are two HDDs attached via SATA running in RAID1 mode. Because everything seemed to be ticking along fine, I screwed everything into the case and... wouldn't boot.
Well, actually, the network interface came up. I could ping the computer. But I couldn't SSH to it and there was no access via the web interface.
I tried three or four times with the same result. In the end, I tried with a monitor and keyboard attached and found that there was a message on the console telling me to log in as root for maintenance or press Ctrl-D to continue.
The problem is that I'm planning to run this headless. Having it pause like that is not useful.
What causes this? I found that one of the two disks had disappeared from the raid setup and I had to use the recover option. But the system is booting from SD card. Any idea how I can stop this from happening in the future?
