I had something like this happen some years ago on a workstation with
2-disk (software/Linux) RAID 1. Turns out one of the disks had been ejected
from the raid array. It was that ejected disk that was getting the updates,
but since it was no longer in the array it wasn't being booted, but rather
the other one that wasn't getting the updates.
