I have...had...a lovely 80TB unraid server. Then my house flooded and everything is destroyed. I have backups of the config and docker containers. But it will be awhile before I have hardware to restore them to. Things are tough right now and I really want to get plex back up with a bit of content for my kid so they can have a bit of normalcy. What I do have is a hyper-v server at a friend's house I can setup some VMs on with a tiny bit of storage (at least compared to the server that got flooded). Far from ideal, but better than nothing until I can get things sorted out. Can I run unraid in hyperv as a VM without any USB drives, even in trial mode for a couple weeks? That would let me directly restore all the docker configurations instead of having to setup docker manually on a Ubuntu VM or something. I tried the manual install instructions, mounted a VHD file, format FAT32, name it UNRAID and copy the files over etc. When I boot it, it gets to the point of "Waiting 30 seconds for device with label UNRAID to come online", but can't find the disk. I double checked and when mounting the disk it does come up as UNRAID and a FAT32 drive. So I can't get past that. I can probably get them to put in a USB drive if needed for licensing the trial license or even installing to, but not sure if I can boot from that in Hyper-V on server 2019. Any ideas how I can get something running temporarily? I'd be very grateful for any ideas you might have.

I have my unraid server attached to a separate disk shelf for more storage (because they just don't build big cheap cases like they used to). Not a real commercial disk shelf, just an old case with a PSU, SAS expander card and drives in it, connected via external SFF-8088 cables to a HBA in the server. Right now both the server and disk shelf are on the same UPS, so if they lose power and the UPS dies, at least they die at the same time and it's no different than if they were all in the same machine. But I'm thinking I may need to split them up across 2 UPSes. Which means that one UPS might fail before the other. Even if I don't use 2 UPSes, this could come up if the power supply in the disk shelf dies. What is likely to happen if unraid suddenly loses access to half its disks while the array is running?
