13.2. Upgrading cns-deploy and Heketi Server

The following commands must be executed on the client machine. If you want to set up a client machine, refer Section 5.2.1, “Installing Red Hat Gluster Storage Container Native with OpenShift Container Platform on Red Hat Enterprise Linux 7 based OpenShift Container Platform Cluster ” or Section 5.2.2, “Installing Red Hat Gluster Storage Container Native with OpenShift Container Platform on Red Hat Enterprise Linux Atomic Host OpenShift Container Platform Cluster”.
  1. Execute the following command to update the heketi client and cns-deploy packages: 
    # yum update cns-deploy -y 
# yum update heketi-client -y
    Copy to Clipboard Toggle word wrap
  2. Backup the Heketi database file 
    # oc rsh <heketi_pod_name> 
# cp -a /var/lib/heketi/heketi.db /var/lib/heketi/heketi.db.`date +%s`.`heketi --version | awk '{print $2}'`
# exit
    Copy to Clipboard Toggle word wrap
  3. Execute the following command to delete the heketi template 
    # oc delete templates heketi
    Copy to Clipboard Toggle word wrap
  4. Execute the following command to install the heketi template: 
    # oc create -f /usr/share/heketi/templates/heketi-template.yaml
template "heketi" created
    Copy to Clipboard Toggle word wrap
  5. Execute the following command to grant the heketi Service Account the neccessary privileges: 
    # oc policy add-role-to-user edit system:serviceaccount:<project_name>:heketi-service-account
# oc adm policy add-scc-to-user privileged -z heketi-service-account
    Copy to Clipboard Toggle word wrap
    For example, 
    # oc policy add-role-to-user edit system:serviceaccount:storage-project:heketi-service-account
# oc adm policy add-scc-to-user privileged -z heketi-service-account
    Copy to Clipboard Toggle word wrap
  6. Execute the following command to generate a new heketi configuration file: 
    # sed -e "s/\${HEKETI_EXECUTOR}/kubernetes/" -e "s#\${HEKETI_FSTAB}#/var/lib/heketi/fstab#" -e "s/\${SSH_PORT}/22/" -e "s/\${SSH_USER}/root/" -e "s/\${SSH_SUDO}/false/" -e "s/\${BLOCK_HOST_CREATE}/true/" -e "s/\${BLOCK_HOST_SIZE}/500/" "/usr/share/heketi/templates/heketi.json.template" > heketi.json
    Copy to Clipboard Toggle word wrap
    • The BLOCK_HOST_SIZE parameter controls the size (in GB) of the automatically created Red Hat Gluster Storage volumes hosting the gluster-block volumes (For more information, see Section 9.2, “Block Storage”). This default configuration will dynamically create block-hosting volumes of 500GB in size as more space is required.
    • Alternatively, copy the file /usr/share/heketi/templates/heketi.json.template to heketi.json in the current directory and edit the new file directly, replacing each "${VARIABLE}" string with the required parameter.

      Note

      JSON formatting is strictly required (e.g. no trailing spaces, booleans in all lowercase).
  7. Execute the following command to create a secret to hold the configuration file: 
    # oc create secret generic heketi-config-secret --from-file=heketi.json
    Copy to Clipboard Toggle word wrap
  8. Execute the following command to delete the deployment configuration, service, and route for heketi: 
    # oc delete deploymentconfig,service,route heketi
    Copy to Clipboard Toggle word wrap
  9. Execute the following command to deploy the Heketi service which will be used to create persistent volumes for OpenShift: 
    # oc process heketi | oc create -f -
    Copy to Clipboard Toggle word wrap
    For example: 
    # oc process heketi | oc create -f -

service "heketi" created
route "heketi" created
deploymentconfig "heketi" created
    Copy to Clipboard Toggle word wrap
  10. Execute the following command to verify that the containers are running: 
    # oc get pods
    Copy to Clipboard Toggle word wrap
    For example: 
    # oc get pods
NAME                             READY     STATUS    RESTARTS   AGE
glusterfs-0h68l                  1/1       Running   0          3d
glusterfs-0vcf3                  1/1       Running   0          3d
glusterfs-gr9gh                  1/1       Running   0          3d
heketi-1-zpw4d                   1/1       Running   0          3h
