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 # zpool list NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT rpool-25582 69.5G 92.5K 69.5G - 0% 0% 1.00x ONLINE /mnt/rpool-25582 # zpool export rpool-25582 # zpool import rpool # zpool list NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT rpool 69.5G 134K 69.5G - 0% 0% 1.00x ONLINE - 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 == Fix == Upstream zfs commit 4ceb8dd6fdfd ("Fix 'zpool create -t <tempname>'") == Test == Without the fix, creating a pool with -t will show an error message such as: "cannot create 'rpool': no such pool or dataset" and will return an error number even though it successfully created the pool. With the fix, the error is not shown and it exits with 0. E.g. pool 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 == Regression Potential == Small. This is an upstream fix that is know to fix the error. There are no known subsequent changes to the fix hence suggesting it is a good fix. The change is very limited and testing shows it does not break any of the kernel team's ZFS regression testing.
