> Currently there are following problems with our OS cluster:
> * docker on nodes is using loopback devices which is strongly discouraged for production use
> * small partition for imagefs and nodefs which is causing issues "The node was low on resource: imagefs"
> * different root passwords
> We need to:
> # investigate recommended partitioning for production OS clusters (also think about RAID versions available on each blade)
> # reinstall RHELs with recommended partitions
> # Configuring Docker Storage as described in https://docs.openshift.com/container-platform/3.9/install_config/install/host_preparation.html
> # install OS 3.9
> # create mojo documentation
