Are you seeing issue or error message which says auto_unmount option is not valid  ?

Can you please let me the issue you are seeing with 1.7.3 ?

Hi all,

I am testing K8s 1.7.3 together with GlusterFS and have some issues

is this correct?

- Kubernetes v1.7.3 ships with a GlusterFS Plugin that depends on GlusterFS 3.11

- GlusterFS 3.11 is not recommended for production. So 3.10 should be used

This actually means no K8s 1.7.x version, right?

Or is there anything else I could do?

best Christopher
