First you need to "br= eak" the mirror: # zpool detach tank =E2=80=8Bgpt/tankssdzil1 That will make the log vdev into a single-disk vdev, and then you can remove it: # zpool remove tank =E2=80=8Bgpt/tankssdzil0 After that, you should be able to re-enable the bootfs option and reboot to make sure everything is still working. --=20 Freddie Cash fjwcash@gmail.com
