From 3c5586b3e8772f0a9d25502c9b4474e987ecc656 Mon Sep 17 00:00:00 2001 From: Avra Sengupta Date: Fri, 11 Mar 2016 15:27:30 +0530 Subject: snapshot/quota: Copy quota.cksum during snapshot operations Backport of http://review.gluster.org/#/c/13760/ A volume having a quota.conf file, should always have a quota.cksum file too. Based on this above assumption modifying glusterd_copy_quota_files() to always copy quota.cksum, if quota.conf is present. This change will be reflected when a snapshot is created, restored and cloned.
