Hi,
I've got a Proxmox installed on a ZFS RAID1. I've also noticed that the two root disks have 3 partitions: "BIOS boot", "EFI system" and "ZFS".
I wonder what happens, when one of the root disks fails. For ZFS it should not be a problem, but what about booting the system? Are the first 2 partitions redundant and Proxmox can still boot with one disk removed?
After changing the failed disk, what has to be done?
