Client.admin authentication error

今天早上在ceph的跳转机上运行ceph -s突然出现一个错误

[root@dev-yum ~]# ceph -s
2016-08-29 10:05:31.853233 7fa5cf941700 0 librados: client.admin authentication error (1) Operation not permitted
Error connecting to cluster: PermissionError

好眼熟，就是认证出问题了。
去检查一下client.admin的keyring

[root@cloud-11 ~]# ceph auth list

说明client.admin的keyring是添加进去了的，本地跟ceph一致应该就没问题，再去检查一下本地。

[root@dev-yum ~]# cat /etc/ceph/ceph.client.admin.keyring
[client.admin]
key = AQCJoPRW0N0tOBAA59XPMetKwQ5MizV0ZXot9Q==

这样问题就清楚了，把keyring改成ceph里面的就行了。估计是我前两天重装了ceph，ceph又会自动重新生成密钥，但是我就是在这台跳转机上装的，它难道就不会自动更新一下keyring么。
