1. 查看出错的详细信息

   ceph health detail

2. 启用资源服务(主要的设置资源池种类，方便做好分类)
   

3. 查看资源池的分类

ceph osd pool application get demo

4. 查看crash的情况

   ceph crash ls

   查看具体的crash情况

   ceph crash info <id>

   删除crash报警（如果是误报的话）

   ceph crash archive <id>

   ceph crash archive all

   直接删除crash

   ceph crash rm {crash-id}

5. 解决时间偏移警告

   • 查看当前对应结点时间

     ntpd -pn

   • 先停掉时钟同步

     systemctl stop ntpd

   • 更新时间

     npdate {第一步的结果}

   • 写入到硬时钟，以便机器重启时读取

     hwclock -w

   • 重启时钟服务

     systemctl restart ntpd

6. 代码调试

   如上命令可能会导致执行失败

   用以下的命令

   其实.asok文件在

   /var/run/ceph/文件下

   ceph --admin-daemon ceph-client.rgw.ceph119.2198988.94410876256936.asok config show|grep ssl

   ceph --admin-daemon ceph-client.rgw.ceph119.2198988.94410876256936.asok config set debug_rgw 20

   注意加上 ” --admin-daemon “

7. 认证出现问题一定要查看下客户端与集群内部时间是否一致

   集群內部时间查看：就是看ceph的log信息打印的日志时间

   客户端时间查看：就是当前linux主机的时间 date -R

   两者如果不一致将会导致很多错误，这说明两个ntp服务对于分布式存储来说十分重要

   比如下面的情况就是因为集群与客户端时间不一致这样引起的
