 1、修改配置

[root@node2 ~]# vim /etc/ceph/ceph-cluster/ceph.conf 
[global]
fsid = 4c137c64-9e09-410e-aee4-c04b0f46294e
mon_initial_members = node2,node1,master1
mon_host = 172.16.18.22,172.16.18.24,172.16.18.16
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx

osd pool default size = 3
public network = 172.16.18.22/24

[mon]
mon allow pool delete = true

 

2、文件同步

[root@node2 ceph]# cp /etc/ceph/ceph-cluster/ceph.conf /etc/ceph/
[root@node2 ceph]# ceph-deploy --overwrite-conf config push node1 master1

 

 3、新增monitor

ceph-deploy --overwrite-conf mon create node1 master1

 

4、检查

[root@node2 ceph-cluster]# ceph -s
