Whats the best config set up for my set up ?

[nytram]

Hi

I moved to Proxmox before Christmas and have been impressed with how it all works. So now I want to improve my setup. I have a Proxmox machine with 2 containers (DNS and Webserver) and 1 VM for Home assistant on a machine with just 1 SSD on ext4.

I now have a Dell i7 - 6700 @ 3.4GHZ (4 cores and 8 threads) with 16GB and it has a M2 drive and 3 SSD's and 2 Ethernet ports.

Id like to use OPNSensor or PFSense once I have my set up created also.

I was aiming to

have the m2 drive just to install Proxmox on
2 of the 500GB SSDs make a mirror (raid 1) on the ZFS disks
1 SSD to keep the backups on and then upload to my Google Drive as backup.
VM OPNSense or PFSense Firewall

How is the best way to move my current VM and Containers from the old set up, Will my old server just appear in my datacenter on my new server and move (via a drag and drop) or better to clone ?

Also, how would I get this all set up the VMs on the ZFS Raid1 and not the boot drive ?

Any Advice will be appreciated.

Thanks in Advance

Martyn

Do you plan to keep both machines or switch over to the new one? If you plan to switch, then the best way is to create backups, move them over to the new server (or access the same network share), and restore them.

I recommend that you also mirror the boot drive. Otherwise, everything will be down if it fails.

16GB of RAM is not much nowadays. If you can add more, you'd most likely be happier. Also depends highly on the guests. But having enough available for the host itself is never wrong. ZFS is also happy if there is enough RAM available to use it as cache (RAM is still much faster than an SSD).

You can create a new ZFS pool on the drives. Either via the GUI or command line. Configure a ZFS storage on it (can be done automatically when creating the ZFS pool via the GUI) and then you can either move the disks of your guests to that storage, or select that storage when you restore the guests from the backups.

Hi

I was planning on closing the original Proxmox machine down and replacing it. I only have 3 sata connections on the board the SSD's were using but I could use 1 for the boot mirror and just move my backups to the a USB hard drive and google drive.

Thanks for confirming everything. I will look at adding more RAM also.
