Delete an SSD compatibility

You can delete an SSD compatibility. If you do this, any nodes that are part of a node pool because of this compatibility are removed from the node pool.

About this task

Caution Image
Deleting an SSD compatibility could result in unintended consequences. For example, if you delete an SSD compatibility, and fewer than three compatible nodes are removed from a node pool as a result, these nodes are removed from your cluster's available pool of storage. The next time the SmartPools job runs, data on those nodes is 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 form their own node pool, but data is restriped. Any file pool policy pointing to the original node pool points instead to the node pool's tier, if one existed, or, otherwise, to a new tier created by OneFS.


  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 SSD 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. The check boxes describe the result of the operation.
  3. Select all check boxes in the dialog box, and click Confirm.


The SSD compatibility is deleted, and the new state of the affected nodes appears in the Tiers & Node Pools list. For example, a previously provisioned node is now unprovisioned.
