Delete a node class compatibility

You can delete a node class compatibility. As a result, any nodes that were provisioned to a node pool because of this compatibility are removed from the node pool.

About this task

Caution Image
Deleting a node class compatibility could result in unintended consequences. For example, if you delete a compatibility, and fewer than three compatible nodes are removed from the node pool, those nodes will be removed from your cluster's available pool of storage. The next time the SmartPools job runs, data on those nodes would be restriped elsewhere on the cluster, which could be a time-consuming process. If three or more compatible nodes are removed from the node pool, these nodes will form their own node pool, and data will be restriped. Any file pool policy pointing to the original node pool will now point to the node pool's tier, if one existed, or, otherwise, to a new tier created by OneFS.

Procedure

  1. Click File System > Storage Pools > SmartPools.
    The SmartPools tab displays two lists: Tiers & Node Pools and Compatibilities.
  2. In the Compatibilities list, next to the compatibility that you want to delete, click Delete.
    The Confirm Delete Compatibility dialog box appears with one or more check boxes that you must select before proceeding.
  3. Select all check boxes in the dialog box, and click Confirm.

Results

The compatibility is deleted, and the new state of the affected nodes appears in the Tiers & Node Pools list.
