From 75c5700acb2363a47427e29e612f9a068010bfd6 Mon Sep 17 00:00:00 2001 From: Jeffrey Zhang Date: Tue, 20 Jun 2017 09:29:59 +0800 Subject: [PATCH] Revert "Fix a typo and complement doc in ceph-guide.rst" This reverts commit 4e8bd619dda87c256ff6a06287de9d7c0f6c0dff. The original doc is correct. The 5GB journal is create in ceph-osd bootstrap script in kolla code base[0]. And there is no script to handle KOLLA_CEPH_OSD_BOOTSTRAP_D label too.
