Proxmox with PBS in VM

[Tibor Egyed]

I have a small Proxmox cluster, and I installed a PBS in VM with HDD passthru (---virtio1=/dev/disk/by-id/....).
I thought it would be good for me, because if something goes wrong, i just reinstall the full Proxmox cluster, then create a VM and give them the hdd and it's done and start the recovery.

I thought so until the first reboot. (Proxmox PVE reboot, not PBX reboot)

Even if the boot HDD is set in the BIOS, booting will stop because there are more then one "rpool"exists.

Any idea to resolve this case?

PVE boots fine?
If you plan to basically pin the PBS installation to the VM by passing through the disk directly, habe you considered installing PBS alongside PVE on the same hardware and not into a VM? https://pbs.proxmox.com/docs/installation.html#install-proxmox-backup-server-on-proxmox-ve

If I remove the HotSwap HDD with PBS Disk, then yes, the PVE boots fine.
I dont plan that scenario when install the PVE and PBS same machine, because if then Node has hardware error (motherboard etc), then I just remove the PBS HDD and put it the other Node.

Unfortunately, I realized today that the situation is even worse, if there is any ZFS disk in the PVE hardware, it won’t even boot.
