I attempted to spin up OMV 5 under Proxmox 6. When I defined the KVM VM, I only created a 10G drive space to act as the boot drive. After starting the VM, I attempted to update the system from web interface, which failed. I then ssh'd into the VM and tried a apt upgrade which failed. I thought that here was some issue with my network connection, but pinging external hosts had no problems.
I took a look at the / filesystem, and realized the filesystem was "ro". I had noticed when I was installing, there was failure to connect to any of the repositories, but I wrongly assumed there was some problem so I skipped installing a repository mirror. I now realize that there was some issue going on and I didn't notice it. I set up the VM to use one of my VLANs, which does get it address from the VLAN dhcp server, so I am at a loss.
I attempted to re-install, but once again, there is a failing when "configuring the package manager". There would seem to be a network problem at the point. Needless to say, that when I skip the section on package manager, the VM does finish, but at this point, the drive is in ro mode.
Any pointers would be greatly appreciated!
