Dear all,


I currently have the problem that my boot partition is only 64kb which
is not enough for freebsd 11 new zpool version.

So I removed one disk from my zpool mirror.

Corrected the partition size to 256kb and copied all data with zfs
send/receive to the new pool.


The zpool name changed from tank to zroot.


I would modify on the new pool the loader.conf and the bootfs option for
the new pool by:

zpool set bootfs=3Dzroot/ROOT/default zroot

But I fear a little bit that at a reboot the new pool zroot and the old p=
ool tank is mounted to / which would cause serious problems.



Is there a way to prevent the mount from pool tank at next boot?

I would not like to destroy the pool (tank) till I can boot the new one w=
ithout problems.

Thanks
Matthias
