kolla-ansible 重新部署 ceph-mon 组件

1.备份数据

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

2.删除掉docker volume ls下的卷

 [root@controller ~]# docker volume ls
 DRIVER              VOLUME NAME
 local               c1153187c7804f2ee02c2352a8f7e54037a3cd4425501429aa07f82f914fab11
 local               ceph_mon
 local               ceph_mon_config
 local               cinder
 local               elasticsearch
 local               glance
 local               grafana
 local               haproxy_socket
 local               influxdb
 local               keystone_fernet_tokens
 local               kolla_etcd
 local               kolla_logs
 local               magnum
 local               mariadb
 local               neutron_metadata_socket
 local               openvswitch_db
 local               rabbitmq
 [root@controller ~]# docker volume rm ceph_mon ceph_mon_config

3.开始部署 ceph-mon

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

4.恢复数据

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

5.重启 ceph-mon 容器

 [root@controller ~]# docker restart ceph_mon
