ceph增加mon节点报错admin_socket: exception getting command descriptions: [Errno 2] No such file or directory

[node3][ERROR ] admin_socket: exception getting command descriptions: [Errno 2] No such file or directory

[node3][WARNIN] node3 is not defined in `mon initial members`

[node3][WARNIN] monitor node3 does not exist in monmap

[node3][INFO  ] Running command: ceph --cluster=ceph --admin-daemon /var/run/ceph/ceph-mon.node3.asok mon_status

[node3][ERROR ] admin_socket: exception getting command descriptions: [Errno 2] No such file or directory

[node3][WARNIN] monitor: mon.node3, might not be running yet

解决办法：

修改集群下面的ceph.conf配置文件（增加mon节点主机名和IP地址）以及增加public network

完整配置文件如下

[global]
fsid = 57e0373d-3f5e-453f-a172-3004586b3a54
mon_initial_members = node1,node2,node3
mon_host = 172.18.1.227,172.18.1.228,172.18.1.229
auth_cluster_required = cephx
auth_service_required = cephx
auth_client_required = cephx

public network = 172.18.1.0/24

[root@node1 cluster]# ceph-deploy --overwrite-conf mon  add  node3 --address 172.18.1.229
