One of my systems has recently had its data-disks recreated on a new pool. However, after a reboot the system hangs on trying to import pools from the cache file. I'm puzzled by this, since I specifically exported the old pool and set the new pools mount property to noauto.
I need to figure out how to either tell systemctl which pools it needs to import, or somehow clear any erroneous pools from the cache file. I will be working on the former for now to get up and running again. In the meantime, is there a way to see which pools are in the cache file? Any advice on how to handle a situation like this so I won't be in a similar dilemma in the future?
Thanks!

You can remove the cache file and let it rebuild on its own.

That was my idea as well, but since my root-pool is on ZFS, I would have to ensure that that one has been added to the new cache file before I reboot out of my rescue environment. Since the cache file is inside the mounted pool, would I need to set the cachefile property to an alternate path, rename/remove the original then set the cachefile property back to the original? Plus, it might not help me if I import another pool into the cachefile and do a clean shutdown, since the next boot would then try to mount it. More granular control of the import would be better. A custom unit-file perhaps?

It works amazingly though. Check out this advanced application. That said, I found that setting the cachefile property on an imported pool creates a clean cache file, overwriting if wanted. So my system is up and running again. I just need to mind that I import my other pools into their own cache file (or without one). I'll leave the question open to see if someone has a means of granular control (possibly a custom systemd unit file). Thanks for the really fast reply!
