+===== 2 openstack用設定 =====
+==== openstack用のpoolを用意しておく ====
+<code>
+# ceph osd pool create volumes
+# ceph osd pool create images
+# ceph osd pool create backups
+# ceph osd pool create vms
+# rbd pool init volumes
+# rbd pool init images
+# rbd pool init backups
+# rbd pool init vms
+</code>
+==== openstack用のkeyingを用意しておく ====
+<code>
+# ceph auth get-or-create client.glance mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=images' -o /etc/ceph/ceph.client.glance.keyring
+# ceph auth get-or-create client.cinder mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=volumes, allow rwx pool=images' -o /etc/ceph/ceph.client.cinder.keyring
+# ceph auth get-or-create client.nova mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=vms, allow rx pool=images' -o /etc/ceph/ceph.client.nova.keyring
+# ceph auth get-or-create client.cinder-backup mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=backups' -o /etc/ceph/ceph.client.cinder-backup.keyring
+</code>
+==== OpenStack設定変更 ====
+このrbd-1ってのが、cephになります。
+<code>
+# vi /etc/kolla/globals.yml
+# Cinder
+enable_cinder: "yes"
+enable_cinder_backend_nfs: "yes"
+skip_cinder_backend_check: True
+cinder_enabled_backends:
+  - name: rbd-1
+  - name: linstor-drbd
+  - name: nfs-1
+# Cinder-Backup
+enable_cinder_backup: "yes"
+cinder_backup_driver: "nfs"
+cinder_backup_share: "192.168.0.101:/nfs"
+## ceph
+glance_backend_ceph: "yes"
+cinder_backend_ceph: "yes"
+</code>
+==== ceph.conf修正 ====
+ansibleを流すときに、ceph.confにタブがあると失敗するのでタブを削除
+  sed -i 's/\t//'g /etc/ceph/ceph.conf
+==== ceph用のファイル用意 ====
+<code>
+mkdir /etc/kolla/config
+mkdir /etc/kolla/config/nova
+mkdir /etc/kolla/config/glance
+mkdir -p /etc/kolla/config/cinder/cinder-volume
+mkdir /etc/kolla/config/cinder/cinder-backup
