Temporarily replace disk in mirror with bigger capacity. Is this possible
I currently have a 12TB 2x disk mirror with a potentially failing disk. The failing disk is under warranty and will be replaced, but while I’m waiting for the replacement, I’d like to put a spare 16TB disk into the mirror as its replacement temporarily and then swap the new 12TB disk into place when I receive it.
I know it’s not possible to use a smaller disk into a pool that’s been expanded to a larger capacity, but being that I’ll be mixing a 12TB and 16TB disk, my pool will stay at 12TB. Is this possible?
