    How to solve the installation and future reinstallation of PVE

    I'm not an expert and I often use AI, but sometimes I get lost in AI too. My situation is as follows. I have 3 NVMe disks 1x 1TB and 2x 512GB. I install proxmox (ext4) on the 1TB disk. Proxmox automatically divides the disk into root 100GB (swap 8GB) and lvm 850GB. What is my goal? I want only...

    Proxmox VE installation and 3 disks

    I want to buy a mini PC (ALLIWAWA, Ninkear, GMKtec, Blitzwolf, AOOSTAR ...). Some mini PCs have 3x NVMe slots. I will install proxmox on an NVMe disk (EXT4). The other 2 NVMe disks will serve as data storage for LXC/KVM, e.g. nextcloud data, plex data, etc ... These 2 disks will be a ZFS Raid1...

    How do you backup?

    I have only one node in my home lab. So far I have 15 x LXC and 2 x KVM. I make backups via the web interface using vzdump. I then copy the backups to a USB key. I would like to store backups in some cloud (e.g. gdrive). I don't need synchronization, just simply create a backup and send it to...

    Wireguard in LXC

    When I had Proxmox 7.x, I also used Wireguard in LXC. I always set it accordingly. In the summer of 2023, I switched to Proxmox 8.x and forgot to do this setting, and Wireguard still works in LXC. Is it necessary to do this setting only for OpenVPN, or also for Wireguard? Someone answered on...
