@scottalanmiller said in ZFS Pool Online but Cannot Import:
One big thing we've learned about ZFS risks is that it forces a situation where we are dealing with enormous pools of block data in order to do anything and the ability to copy, image, move, backup and so forth is heavily curtailed by the fact that we are forced to work at the array level before ZFS merges the RAID, LVM and filesystem layers together into a single monolith that, if it fails, leaves you so dramatically exposed.
Yep. Just because LVM and MD are separate things, that's not necessarily a bad thing. Especially if you've got devices that can change where they are in the /dev system.
