In most cases, the Aria Operations cluster has automatically been taken offline. If the cluster is not offline, log into the Admin UI as admin and click the Take Offline button to take the cluster offline. Do not proceed unless the cluster is offline.
Note: All analytic nodes must have the same amount of space in the /storage/db logical volume.
Only perform the following steps on Analytic nodes (Primary, Primary Replica, Data).
