[PVE 8] ZFS Mirror Boot Pool on PVE: Guide to Replace Failing Disk in 2025?

[SInisterPisces]

Hello,

I tried to google this, but found some pretty old results that were focused on PVE 7. I'm not sure valid those still are. I also found plenty of results for just replacing a disk in a standard mirror pool, but I think the PVE rpool is different because of how it's partitioned.

Assume I've got a single vdev mirror pool that's acting as my rpool. One of the disks has started screaming about its failure and impending demise via zpool status.

What step-by-step guide to replacing the dying disk should I be looking at?

Still in the reference documentation and still valid:
