Hello engineers, I recently configured my Proxmox instance with ZFS RAID1 (I need to test the recovery process :)). I then added three additional SSD disks and partitioned them with this command: mkfs.ext4 -L SSD-256GB /dev/sdX - -L: label flag - SSD-256GB: label (adjust for each disk, e.g., SSD-1TB, SSD-128GB) After that, I mounted them via /etc/fstab like this: UUID=4c1cebaf-8142-4b79-a0ea-45c26253ed75 /media/ssd-1-TB ext4 defaults,noatime,nofail 0 2UUID=b012b34c-bb86-408a-bebf-a91d1a1d3a49 /media/ssd-256-GB ext4 defaults,noatime,nofail 0 2UUID=55c39d33-8665-4ba6-9b45-1c513df36296 /media/ssd-128-GB ext4 defaults,noatime,nofail 0 2 Now I have three extra disks for playing around with :) Let me know how you use additional disks in Proxmox.
