How does it work if my ssd dies, where proxmox boot and the lvm for the containers is located on? Would i have to reinstall proxmox + pbs again and then id be able to restore the disk again? or do i habe to install pbs on another drive altogether and then id be able to restore my boot drive + lvm?

the machines are located next to each other and i run 2 currently because 1 was originally a truenas server and the other one a proxmox-server with my services. Since truenas stopped publishing its open source code to github i reinstalled it with proxmox. im also just started setting everything up and i wanted to have my services running while i figure out how i want to run my media server. originally i tried open media vault instead of truenas, but since i virtualize stuff like jellyfin anyways i thought that running that directly in proxmox is easier.

if that n100 cpu can run everything i need on the media server, i want to move the containers over. otherwise the two n100 machines stay.

If you only have 1 disk on your server (no RAID), you will have to

buy a disk

install in server

reinstall Proxmox VE

Install Proxmox BS

have a regular backup on some other disk (e.g. USB HDD) to restore other VMs from

and the lvm for the containers is located on?

Are you talking about containers (lxc, docker) or the VM disks? You need a backup for VM disks anyway (Proxmox BS).

If you’re talking about containers, I do not know how to backup those. I do use docker containers but they’re all inside VMs. I like to seperate things via VMs, as a rogue container taking down it’s VM (or having other negative effects on its host) is less of a headache than a rogue container taking down the whole hypervisor because it’s running directly on the that.

For comparison, this is my disk setup for my server (my old PC):

# lsblk nvme0n1 259:0 0 465.8G 0 disk nvme1n1 259:1 0 465.8G 0 disk sda 8:0 0 3.6T 0 disk sdb 8:16 0 3.6T 0 disk sdc 8:32 0 3.6T 0 disk # zpool list NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT data_raid 10.9T 2.40T 8.51T - - 26% 21% 1.00x ONLINE - rpool 460G 7.31G 453G - - 8% 1% 1.00x ONLINE -

The 2 NVME-disks are used in a ZFS mirror (rpool in zpool list above) and store the Proxmox OS. The 3 SATA SSDs (see sd* in lsblk above) are housing all VM data in a ZFS RAID-Z1 called data_raid. With this hardware- and RAID-setup, one disk of each zpool could die right now and all I’d have to do is pay the currently horrendous hardware-prices and replace it. No data-loss or downtime until at least 2 disks of a single zpool die together.

All hardware dies at some point. Preperation is key.

  My Mainboard only supports a single nvme-drive. thats why i store the os and the data of my vm/lxc on it. everything else are good old hdd. is it possible to restore this drive, if i install pbs as a lxc on this very drive?
  
  sorry, i tried to read through some guids already and the more i read the more im confused /(

    You should not be able to restore the whole drive, like you would restore a VM. This is because you would first need to have Proxmox VE already running to restore the drive which runs Proxmox VE.
    
    If your NVME drive dies, you would have to do what I outlined above:
    
    get new NVME drive, install in server
    
    install Proxmox VE manually
    
    install Proxmox BS manually (either lxc container or VM)
    
    give Proxmox BS access to backups on external HDD
    
    restore whatever you backed up
    
    Though, to reiterate, I do not know anything about lxc containers.
    
    I did go through the Proxmox VE backup settings on my server, but I could not find a way to backup lxc containers, only VMs. So maybe Proxmox VE does not support backing up lxc containers? Or maybe it just does not show any lxc container backup option because I do not run any lxc containers?
    
    I did find this github about Proxmox VE and LXC containers, but I didn’t test it and it only has 1 star, so I’d be wary.
    
    As a tipp: Even if your motherboard only supports 1 NVME drive, you might still be able to use multiple. You could buy a PCIe card with M.2 NVME slots, if you have any unused PCIe slots on your mainboard. With this, you should still be able to have a RAID setup.

    thx for that write up. seems i didnt understand you correctly the first time (english is not my native language). i already used all pci-slots with sata extensions and a nic. its just a mini atx board with a n100 cpu, so my options are limited. i could mirror the disk to a sata ssd though.
