I deleted the shares. move the kubernetes pool from this pool but still get this error. I am selecting all options when exporting.
anyone have any suggestions?
i checked and no containers are using this pool and i also shut down all containers but still got the same issue.
UPDATE: whatever was the cause of it doing a reboot and trying again worked.
