Replacing a damaged disk in ZFS is easy due to the built-in tools and commands it has to offer the user. If you experience a faulted disk in your Proxmox ZFS array you can replace it with the steps below. If your replacement disk is larger than the existing disk enter the below command to ensure your pool will automatically grow to the new size once all disks have been replaced to match the larger size.
To start, all of your disk’s will have to be the same size and installed into the Proxmox server before configuring. I prefer to create a label for the drive bay with the disks serial number for easier management in the future. Wipe Drives In the Proxmox web interface click on the name of your server in the tree to the left and then choose disks in the following menu.
