- Astra Trident
- CSI-Snapshot supporting backend driver
Using a PVC, creating a
CSI-Snapshot, and a
StorageClassto create a PV from that snapshot, it doesn't matter which
storagePoolsdefinition exists in the StorageClass, the clone PVC will always be created in the same Trident backend (e.g. SVM, driver) used by the original PVC, which also holds the Snapshot information.
For example, for ONTAP that means that the volume (and containing LUN) will appears in the same aggregate and SVM.
It cannot be created for a different backend with the same (and definetely not a different) driver, within the set of trident supported storage, e.g. by manipulating the StorageClass'
storagePoolssetting. However, even when trying to retarget the backend, it will not fail the process, instead it will just not apply the requested storagePools or backend change.
