A really common way this happens is backup up to a remote server using NFS or CIFS. The mount fails for whatever reason and the backups get written to the directory where the remote is supposed to be mounted. That's why everyone is suggesting you...

While it may not have messed with the network, it may have messed with the web page. Some of those scripts purport to remove the "nag screen" and as a result they can cause problems when PVE is newer than when the script was last updated.
I'd either let PVE manage the ZFS pool and give OMV storage from that (ext4 inside) or pass a whole controller through to it. I'm not personally a fan of giving a guest a whole part of my hardware as it goes against my idea of a hypervisor.
This is that section of my /etc/network/interfaces. You need to use "nano" or "vi" to edit yours to look similar. Replace the "bridge-ports" line with whatever the name of your Ethernet device is (mine being enp191s0) and the address and gateway...
It is very likely to be swapping things out that then never get swapped back in. In which case there's no harm being done, and a slight good in that there's more RAM for caching.
There is the issue of how the VM is stored. If it is on, say, lvm-thin, then the storage can handle the snapshot and the VM is in raw format. If it is on a file storage like NFS, then the image itself must do it, for example by being in qcow...
No, it still doesn't make sense. Proxmox is somehow supposed to know if this was an "intended" shutdown rather than a VM crash, and do something different in that case. And you want "on demand" machines to have high availability? What the heck...
What is the point of HA if you're going to be shutting the VM down for extended periods and it should not run on a cluster restart? On the face of it this does not make any sense.
