When creating a pool with the -t option on Ubuntu 18.04 LTS, it will report an error and return a non-zero exit code, but the pool appears to be successfully created.
For example:
# zpool create -O canmount=off -O mountpoint=none -R /mnt/rpool-25582 -t rpool-25582 rpool /dev/mapper/loop2p1
cannot create 'rpool': no such pool or dataset

I opened an upstream bug against ZFS on Linux, here: https:/ /github. com/zfsonlinux/ zfs/issues/ 7502
And it has been recently fixed, here: https:/ /github. com/zfsonlinux/ zfs/pull/ 7509
Can this upstream fix be pulled into the Ubuntu 18.04 LTS packages?
Thanks,
Prakash
