1、当前状态


2、在172.10.2.172(node2)再添加一个mon（mon.node2）
ssh node2

vim /etc/ceph/ceph.conf   添加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)再添加一个mds
vim /etc/ceph/ceph.conf   添加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 关掉一个后另一个会接管

附：配置文件
root@node1:/var/lib/ceph/osd# cat /etc/ceph/ceph.conf
