Solved How To Set mountroot zfs:zroot/ROOT/default On Boot Up?

[fr33bsd]

Hi,

I just set a new bootup device for the FreeBSD installation.

The kernel is being loaded on boot up from that drive, but then the systems asks for mountroot.

Entering zfs:zroot/ROOT/default make the system boot fine.

How to set mountroot zfs:zroot/ROOT/default so mountroot won't prompt anymore?

mount the device to /mnt/boot/loader.conf
and add line

vfs.root.mountfrom="zfs:zroot/ROOT/default"

You can also set the bootfs property: zpool set bootfs=zroot/ROOT/default zroot

I didn't try it yet, but does your solution work on all setups like when you have a new boot device made by
fdisk -BI /dev/ada0
bsdlabel -B -w ada0s1
newfs -U -O1 /dev/ada0s1a
boot0cfg -v -B -t1 ada0

If you're intending on a ZFS root, you shouldn't be anywhere near any of those commands.

Please stop using fdisk(8), it only supports MBR. And boot0cfg(8) only supports MBR and UFS. So it's not going to work for ZFS.

Can just use gdisk
