Configuring cluster

After successfully installing InfoScale operator, you can create a cluster.

  1. Edit clusterInfo section of the sample /YAML/OpenShift/cr.yaml for InfoScale specifications as under - 

      
spec:
 clusterID: <Optional- Enter an ID for this cluster>
 isSharedStorage: true 
 - nodeName: <Name of the first node>
    ip:
    -  <Optional - First IP address of the first node >
    -  <Optional - Second IP address of the first node>
    excludeDevice:
    - <Optional - Device path of the disk on the node that you want
                               to exclude from Infoscale disk group.>
  - nodeName: <Name of the second node>
    ip:
   -  <Optional - First IP address of the second node >
   -  <Optional - Second IP address of the second node>
    excludeDevice:
    - <Optional - Device path of the disk on the node that you want
                               to exclude from Infoscale disk group.>
  - nodeName: <Name of the third node>
    ip:           
   -  <Optional - First IP address of the third node >
   -  <Optional - Second IP address of the third node>
    excludeDevice:
    - <Optional - Device path of the disk on the node that you want
                               to exclude from Infoscale disk group.> 
.
.
.                                               
 
 YOU CAN ADD UP TO 16 NODES.

 fencingDevice: ["<Hardware path to the first fencing device>",
                  "<Hardware path to the second fencing device>",    
                  "<Hardware path to the third fencing device>", ]
  encrypted: false
  sameEnckey: false

    Note:

    Do not enclose parameter values in angle brackets (<>). For example, Primarynode is the name of the first node; for nodeName : <Name of the first node> , enter nodeName : Primarynode. InfoScale on OpenShift is a keyless deployment.

  2. Run the following command on the bastion node.

    oc create -f /YAML/OpenShift/cr.yaml

  3. Run the following command on the bastion node to know the name and namespace of the cluster.

    oc get infoscalecluster

    Use the namespace from the output similar to the following. 

    NAME                 NAMESPACE        VERSION   STATE     AGE
infoscalecluster-dev infoscale-vtas   8.0.220   Running   1m15s

  4. Run the following command on the bastion node to verify whether the pods are created successfully.

    oc get pods -n infoscale-vtas

    An output similar to the following indicates a successful creation of nodes

    NAME                                 READY STATUS  RESTARTS AGE

After a successful InfoScale deployment, a disk group is automatically created. You can now create Persistent Volumes/ Persistent Volume Claims (PV / PVC) by using the corresponding Storage class.
