How to install rancheros on zfs?

RancherOS
1

Hey,

I have single hdd installed to machine. I’m booting from recent rancheros ISO and following all steps from http://docs.rancher.com/os/configuration/storage/ . So I’m a bit confused: when I have zfs up and running how do I install rancheros on existing zfs?

ros install -c cloud-config.yml -d /dev/sda just overwrites my existing fs.

Any update on this ? I am in the same boat more or less, my servers cant boot from ipxe so I have to install RancherOS on disk and I only have 2 SSD and I want to use them in mirror with ZFS.

Can RancherOS be installed on ZFS ?

http://docs.rancher.com/os/storage/using-zfs/

The docs were recently updated and confirmed working with our most recent release (v0.5.0).

Hi Denise,

Thanks for the reply. The doc is not about installing rancheros on ZFS which is the subject of the topic. RIght now, ros install is targeting a single device and use ext4.

Ideally, we should be able to create the zpool and give it as a target to ros install command.
