+Feature:
+  As a admin
+  I want to cleanup orphaned remote storages
+  So that users will not get undesirable failure
+
+  Background:
+    Given using server "REMOTE"
+    And user "Alice" has been created with default attributes and without skeleton files
+    And using server "LOCAL"
+    And user "Brian" has been created with default attributes and without skeleton files
+
+  Scenario Outline: Clean up the orphaned remote storage after deleting the original shares
+    Given using OCS API version "<ocs-api-version>"
+    And using server "REMOTE"
+    And user "Alice" has uploaded file "filesForUpload/textfile.txt" to "textfile0.txt"
+    And user "Alice" from server "REMOTE" has shared "/textfile0.txt" with user "Brian" from server "LOCAL"
+    And user "Brian" from server "LOCAL" has accepted the last pending share
+    And user "Alice" has deleted the last share
+    And using server "LOCAL"
+    When the administrator cleanups all the orphaned remote storages of shares
+    Then 1 orphaned remote storage should have been cleared
+
+    Examples:
+      | ocs-api-version |
+      | 1               |
+      | 2               |
