Resolving ZFS issue on ‘trick’

I’m gonna follow these instructions to replace a disk in one of my ZFS arrays on my workstation ‘trick’. Have ordered myself a new 6TB Seagate Barracuda Hard Drive for $179. I hope nobody minds if I make a few notes for myself here…

# shutdown # and replace disk
# zpool replace data 9301639020686187487 /dev/disk/by-id/scsi-SATA_ST6000DM003-2CY1_WSB076SN
# zpool status data

Ethernet on ‘trick’

Note to self: I’ve disabled my second NIC enp7s0 for now, I can enable it when its cable arrives.
