kolla-ansible 重新部署 ceph-mon 组件

1.备份数据

1 [root@controller ~]# mv /var/lib/docker/volumes/ceph_mon /var/lib/docker/volumes/ceph_backup/
2 [root@controller ~]# mv /var/lib/docker/volumes/ceph_mon_config /var/lib/docker/volumes/ceph_backup/
3 [root@controller ~]# mv /etc/kolla/ceph-mon /var/lib/docker/volumes/ceph_backup/

2.删除掉docker volume ls下的卷

 1 [root@controller ~]# docker volume ls
 2 DRIVER              VOLUME NAME
 3 local               c1153187c7804f2ee02c2352a8f7e54037a3cd4425501429aa07f82f914fab11
 4 local               ceph_mon
 5 local               ceph_mon_config
 6 local               cinder
 7 local               elasticsearch
 8 local               glance
 9 local               grafana
10 local               haproxy_socket
11 local               influxdb
12 local               keystone_fernet_tokens
13 local               kolla_etcd
14 local               kolla_logs
15 local               magnum
16 local               mariadb
17 local               neutron_metadata_socket
18 local               openvswitch_db
19 local               rabbitmq
20 [root@controller ~]# docker volume rm ceph_mon ceph_mon_config

3.开始部署 ceph-mon

1 [root@controller ~]# mkdir /etc/kolla/ceph-mon
2 [root@controller ~]# kolla-ansible deploy -i /etc/kolla_data/multinode -t ceph

4.恢复数据

1 [root@controller ~]# rm -rf /var/lib/docker/volumes/ceph_mon
2 [root@controller ~]# rm -rf /var/lib/docker/volumes/ceph_mon_config
3 [root@controller ~]# rm -rf /etc/kolla/ceph-mon
4 [root@controller ~]# cp /var/lib/docker/volumes/ceph_backup/ceph_mon /var/lib/docker/volumes/ -r
5 [root@controller ~]# cp /var/lib/docker/volumes/ceph_backup/ceph_mon_config /var/lib/docker/volumes/ -r
6 [root@controller ~]# cp /var/lib/docker/volumes/ceph_backup/ceph-mon /etc/kolla/ -r

5.重启 ceph-mon 容器

1 [root@controller ~]# docker restart ceph_mon
