replacing disk from mirrored root ZFS-Pool

[MisterY]

Hi,

I would like to replace one SSD from the mirrored root ZFS-Pool. How do I do it? I only found a guide for a RaidZ1 in the wiki: https://pve.proxmox.com/wiki/ZFS:_Tips_and_Tricks#Replacing_a_failed_disk_in_the_root_pool

does it work the same?

yes, the process is the same. if the disk you want to replace has not failed yet, I would not take it offline though, especially in a two disk mirror (because once you take one disk offline, you don't have redundancy anymore!). you can simply replace it (then you temporarily have a three-disk mirror, until the replace operation is done). if you are not sure, it is always a good idea to simulate such operations using a VM

it worked!
