Adding storage to an InfoScale cluster

After the existing storage is consumed, you can present new disks to the InfoScale cluster and increase storage capacity. However, these disks are not automatically discovered or added to the InfoScale cluster.

Prerequisites:

  • InfoScale cluster must be 'Running'.

  • Additional storage must be presented to the node and detected by the operating system.

Run the following command:

kubectl/oc annotate infoscalecluster <infoscalecluster name> -n <infoScalenamespace> infoscale.veritas.com/storage-scale-up='enabled'

To monitor progress, run the following command:

kubectl/oc describe infoscalecluster <infoscale cluster name> -n <infoscale namescape>

Review output similar to the following:

  Type    Reason                       Age
  ----    ------                       ---- 
 

  Normal  Storage Scale Up operation:  12m (x2 over 26m)    

  Normal  Storage Scale Up operation:  3m34s (x2 over 18m)  

 From              Message
 ----              -------
 infoscalecluster  Started
 infoscalecluster  Ended

Note:

If the output of the above oc describe command has warning like "Adding new disks in dg failed" then refer to
