I retried having replaced the node that failed and this time all 3 pods started correctly.

If this happens again (I suspect it will) I will report the outputs you mention.

Hi Tim,

Looks like there's a problem to access the Node, or the device (/dev/vdb) on this Node.

Can you share the output of: oc logs of the failing glusterfs POD and the heketi POD?

Best regards,

    I'm having problems deploying GlusterFS to an Origin cluster.

    I have 3 identical nodes for running glusterfs, but the deployment
    seems to randomly fail on one of the nodes sometimes. This is a
    typical error (with the json reformatted). Notice how node 001 and
    003 work fine, but 002 fails.
    All three nodes are equivalent in config.

    Any idea what's going wrong?
