Hello Folks,
I think I experienced this bug upgrading Ubuntu from 18.04 > 20.04 last
night. If not, apologies.
I have the OS running on USB drive, normal install with all my data in a
ZFS pool. After roboot/upgrade completed my ZFS pool is no longer
listed.
Not a ZFS guru so nervous of next
This bug was fixed in the package ubiquity - 20.04.15.1

Ubiquity 20.04 exports existing
I'm working on a patch to only unmount pools that we've mounted as part
of the installation to prevent unmounting pools that don't belong to us.
Regarding your other issue, it is possible that using /dev/sdX for vdev
causes it. Depending on the type of block device these names are not

Title:
Ubiquity 20.04 exports existing ZFS
Something odd is going on, which I don't know if it's expected or not,
as Ubiquity may be intentionally messing with udev.
Specifically, if I have zvols, and run Ubiquity (which exports them),
once I reimport the pool, the zvols have the block devices swapped. I
can reproduce this all the time,
