问题描述
osd.1 用实际环境启动失败的osd代替
OSD服务器关机之后时间较长导致osd被out出去，再次加入时osd日志
/var/log/ceph/ceph-osd.1.log报错如下:

关键信息 init authentication failed: (22) Invalid argument
将mon的auth debug级别设置到10/10可以看到如下信息
ceph daemon mon.$HOSTNAME config set debug_auth 20/20
mon认证报错日志

问题原因
gdb 过程不做说明
gdb调试可知 osd keyring配置错误
解决方法
注释ceph集群服务器上/etc/ceph/ceph.conf [global] 节，重新启动OSD即可
keyring=/etc/ceph/ceph.client.admin.keyring systemctl restart ceph-osd@1
ceph osd tree|grep osd.1
# 输出如下，up后面的字段即为in状态，如果为0或者为空则为非in状态
1 hdd 2.49750 osd.1 up 1.00000 1.00000
等待一段时间，ceph osd tree 看到这个 osd 为 up 且为in则无须做其他操作如果为up 但没有in 执行如下命令即可
ceph osd in osd.1
验证步骤
systemctl status ceph-osd@1 # 状态为
ceph osd tree
# 可以看到该osd节点状态为 up 且 in
