Fixed In Version:
Doc Type: Bug Fix
Doc Text:
Cause: When the atomic-openshift-node service got restarted, all processes in its control group are terminated, including the glusterfs mounted points. Consequence: Each glusterfs volume in OpenShift corresponds to one mounted point. If all mounting point are lost, so are all the volumes. Fix: Set the control group mode to terminate only the main process and leave the remaining glusterfs mounting points untouched. Result: When the atomic-openshift-node service is restarted no glusterfs mounting point is terminated.
