2、在172.10.2.172(node2)再加入一个mon（mon.node2）
ssh node2


vim /etc/ceph/ceph.conf   加入mon.node2的相关配置




ceph-authtool /tmp/ceph.mon.keyring --import-keyring /etc/ceph/ceph.client.admin.keyring


monmaptool --create --add node1 172.10.2.172 --fsid e3de7f45-c883-4e2c-a26b-210001a7f3c2 /tmp/monmap


mkdir -p /var/lib/ceph/mon/ceph-node2


ceph-mon --mkfs -i node2 --monmap /tmp/monmap --keyring /tmp/ceph.mon.keyring


touch /var/lib/ceph/mon/ceph-node2/done


/etc/init.d/ceph start






3、在172.10.2.172(node2)再加入一个mds
vim /etc/ceph/ceph.conf   加入mds.node2的相关配置
/etc/init.d/ceph restart

查看信息多了一个standby的mds
/etc/init.d/ceph stop mds 关掉一个后还有一个会接管
