From abcb46358062e0c99f4f679141a387f6b942491d Mon Sep 17 00:00:00 2001 From: Gaurav Kumar Garg Date: Mon, 14 Mar 2016 14:36:11 +0530 Subject: [PATCH 03/26] glusterd: disabling enable-shared-storage option should not delete volume This patch is a backport of: http://review.gluster.org/#/c/12232/ Previously, when you create volume with "glusterd_shared_storage" name and if user disable, enable-shared-storage option then gluster will delete the "glusterd_shared_storage" volume. With this fix gluster will do appropriate validation of enable-shared-storage option and it will not delete volume with "glusterd_shared_storage" name if it is a user created volume.
