Recently rebuilt my homelab. While restoring files to the new zpools, one of them had a few faults and ended up in a degraded state.
Replacement disk on the way, Hopefully resilvering the pool after disk replacement doesn't cause any more issues. Luckily, all the data is backed up as I recently rebuilt it, so no worries if it explodes.
I'll have to ask Santa for more disks! (And ram, and cores...)
