Freenas not mounting zfs pool

I'm using FreeNAS-11.0-RC2 (a4687be8c) without issues since two weeks ago, then yesterday I did a shutdown, then after powering it on again the zpool wasn't available.

Then after reading this: zfs pool not automatically mounted I added zfs_enable=YES to /etc/rc.conf and now see this:

% zpool list NAME SIZE ALLOC FREE EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT freenas-boot 28.8G 740M 28.0G - - 2% 1.00x ONLINE -

But it isn't mounted, how should I mount this?.

Edit:

This only shows the USB stick I use to boot, but it's not showing my RAIDZ-1 composed of 4x8Tb. The zpool was named 'root'.

Edit 2:

Here's the output of zpool history:

The last two commands where issued by me.
