Proxmox/pfSense storage setup questions for redundancy

Hello! I currently have two SSD's that I can use for Proxmox/pfSense (can buy more if necessary). I would like to have redundancy for Proxmox and the pfSense VM.

Would it be best to do one of the following:
  • Set Proxmox target disk as ZFS Raid 1, then set the pfSense VM as ufs2. In this setup, would it mean that pfSense would run in its own volume (local-lvm) on top of the ZFS Raid1 setup? Wondering the best way to back up the VM in this scenario in case it dies.

    OR

  • Use one SSD as ext4 for Proxmox target disk and put pfSense VM on ufs2 storage on top of that. In this case there is no redundancy, and I would probably have to back up the config file and clone the VM somewhere.

Happy to hear any feedback or suggestions - thank you in advance!
 
Hi,

A backup does not replace Raid1, and a Raid 1 does not replace a backup in any other way.
These two different use cases.
A backup is mainly focused on saving/restore data.
A RAID1 serves primarily to maintain the service and secondly to ensure data protection.

So I would use a ZFS mirror with external backups.

Hi @wolfgang - thank you for your help! I installed Proxmox on root on ZFS as RAID1 in UEFI mode. When rebooting I'm brought into the systemd-boot bootloader. The problem is, I'm stuck there and receive the following image here.

I disabled UEFI boot option in the BIOS and was able to get into the GRUB boot menu and command line login (where I'm told to go to my Proxmox IP:Port for GUI access. Is there a reason why it's not bringing me to the same login page upon landing at systemd-boot menu?
 
I guess you installed PVE in Bios mode?
You have to install PVE when the Bios is set in UEFI and choose the UEFI install.

Weird thing is I installed Proxmox in UEFI mode (Version 6.2), have UEFI mode in BIOS and noticed the "No root device specified. Boot arguments must include a root= parameter".

I have this gallery which shows the zpool (called rpool with mirror-0 vdev and 2 physical SSD's), lsmod to verify zfs module is in kernel, and zfs list to list all the filesystems available.

Are there any other commands I should try to run?
