Volume size and quotas remain after PVC and qtree deletion

Last Updated:

Applies to

Trident for Kubernetes/Openshift


As for the ontap-nas driver, when using the "retain" policy, Trident does not clean up the qtree or the quota on the qtree for ontap-nas-economy, when the PVC is deleted. However, with the ontap-nas-economy driver, when you delete the qtree, you free the space in the volume, but that does not automatically remove the quota, or downsize the volume.
This will cause the following errors on quota commands:
Additionally, this will also cause attempts at creating a new qtree volume for that backend, when space, according to quotas, doesn't fit the new PVC due to the leftover quotas that are no longer qtree backed. If the SVM was set with a maximum number of volumes that has already been reached, the following error will occur:
Cannot create volume. Reason: Maximum volume count for Vserver <SVM> reached.  Maximum volume count is <VOL_LIMIT>.
