These packages form the basic functionality of the production cluster.
Scripts & config files are checked into gitlab under the Kubernetes group project listed.

|---|---|---|---|---|
| BeeGFS Installation | install the parallel filesystem components on controller & nodes to support the /shared filesystem | |||

Storage
The production cluster depends on the /shared filesystem for its persistent storage. The BeeGFS components are installed as shown here:
| component | system | location | storage | size |
|---|---|---|---|---|
| Management Server | ramandu | /home/beegfs-mgmtd | local HD | ~780G (shared) |
| Metadata Server | ramaandu | /home/beegfs-meta | local HD | ~780G (shared) |
| Storage Server | ramandu | /home/beegfs-data | local HD | ~780G (shared) |
Systems that require access to both the development filesystem (/workspace) and the production filesystem (/shared) require a special client configuration.
Dashboard Token
Obtain the token needed to log into the dashboard with this command:
kubectl -n kube-system describe secrets \
`kubectl -n kube-system get secrets | awk '/clusterrole-aggregation-controller/ {print $1}'` \
| awk '/token:/ {print $2}'
The current token for the Production cluster is:
