[Solved]Can Longhorn run with ROS nodes?

#1

As title, I viewed several documents for setting up longhorn. I aware some commands are required and those can’t be installed in ROS unless running those commands as containers.

May I know if ROS nodes work with Longhorn or other OS is required?

Thanks // Hugo

Current RancherOS doesn’t support Longhorn yet. It’s expected to be addressed soon. Once it’s addressed, we will provide updated document for RancherOS.

You can use e.g. Ubuntu 16.04 for the time being.

The RancherOS can be switcht over to a Ubuntu console.
Is it not possible to install the necessary packages with apt on the ROS Ubuntu console?

#4

We just released Longhorn v0.4.1, which added support for RancherOS with CSI driver.

Before v0.4.1, you should be able to use Flexvolume driver with Longhorn but it’s not extensively tested.

#5

Tried to launch LongHorn v0.4.1 (helm from rancher library) on e few RancherOS v1.5.1 nodes with the csi driver option selected in the helm chart, but still getting the openiscsi missing error.

Additional instructions needed?
