i have a box with 9.0.0.1 (for diverse reasons i can't upgrade so not the point) with a 2 disk ZFS mirror.
one of the drives failed, i replaced it with a different brand one, and when i check the webgui in disk|management y saw the old model in the name but the comment showed the new model!.
So i deleted the disk there so that it can de detected with the correct model number....
well that's where things went bad, pressing redetect does nothing, i rebooted, power cycled, powered up with drive removed, i cleansed the disk again just in case, nothing, BUT the disk is shown on the smart info.
if i want to replace it i get:
Code: Select all

what do i do?, do i force the replace?, why isn't it showing on the disk|management even after a rescan?
