Hi everybody,
While trying to rename a zpool from zroot to vega,
I ended up in this strange situation:
nik@vega:~ % zfs list -t all

-------------------------------------------
It seems like there are two pools, sharing the same vdev...
After running a few commands in this state, like doing a scrub,
the pool was (most probably) destroyed. It couldn't boot anymore
and I didn't research further. Is this a known bug?
Steps to reproduce:
install FreeBSD-11.0 in a pool named zroot
reboot into a live-CD
zpool import -f zroot vega
reboot again
Thanks,
Nikos
PS:
Sorry for the cross-posting, I am doing this to share to more people
because it is a rather easy way to destroy a ZFS pool.
