In my home lab I've got an Ubuntu Server 18.04 that's been a physical machine for a long time now. Today I decided to make it virtual and moved it over to my Proxmox server without issue. I'm up and running with one small issue I wanted to get some help on resolving.
When the device was physical I had a software RAID 1 configured. Now that it's been converted I would like to remove that RAID configuration since obviously it isn't needed now. I can't seem to figure out how to remove it using about every guide and suggestion I've found online. Other than saying "degraded" it looks perfectly fine. Like it doesn't notice it's only a single disk now.
