在執行添加ceph擴容節點的時候，異常報錯，沒法添加上擴容節點，報錯以下vim

[root@ceph01 ceph]# ceph-deploy mon add ceph03
.......省略部份內容
[ceph03][INFO  ] Running command: systemctl start ceph-mon@ceph03
[ceph03][INFO  ] Running command: ceph --cluster=ceph --admin-daemon /var/run/ceph/ceph-mon.ceph03.asok mon_status
[ceph03][ERROR ] admin_socket: exception getting command descriptions: [Errno 2] No such file or directory
[ceph03][WARNIN] ceph03 is not defined in `mon initial members`
[ceph03][WARNIN] monitor ceph03 does not exist in monmap
[ceph03][WARNIN] neither `public_addr` nor `public_network` keys are defined for monitors
[ceph03][WARNIN] monitors may not be able to form quorum
[ceph03][INFO  ] Running command: ceph --cluster=ceph --admin-daemon /var/run/ceph/ceph-mon.ceph03.asok mon_status
[ceph03][ERROR ] admin_socket: exception getting command descriptions: [Errno 2] No such file or directory
[ceph03][WARNIN] monitor: mon.ceph03, might not be running yet

報錯提示缺乏public network內部通訊網段，在ceph.conf添加後便可添加節點socket

[root@ceph01 ceph]# vim ceph.conf 
.......省略部份內容
public network = 192.168.100.0/24

執行以下語句下發密鑰，重啓mon服務便可完成添加ide

[root@ceph01 ceph]# ceph-deploy --overwrite-conf config push ceph01 ceph02 ceph03
[root@ceph01 ceph]# systemctl restart ceph-mon.target
[root@ceph01 ceph]# ceph -s
