ceph 问题总结已解决

1. waiting for a volume to be created, either by external provisioner "ceph.com/rbd" or manually create

修改kube-apiserver 配置 添加  --feature-gates=VolumeSnapshotDataSource=true,RemoveSelfLink=false 
重启一下kube-apiserver就可以了

2. clock skew detected on mon.b

查看是不是时间错误没有同步时间  时间同步一下等待几分钟就可以了?

3. ceph 报warning

进入ceph tool容器后查看ceph状态，会发现状态是HEALTH_WARN，下面有一行提示：mons are allowing insecure global_id reclaim
解决办法：禁用不安全模式
 ceph config set mon auth_allow_insecure_global_id_reclaim false
稍后再次查看，ceph status就变成HEALTH_OK了

4. Module 'restful' has failed dependency: No module named 'pecan'

   pip3 install pecan werkzeug #没生效记得重启服务器

5. Error ERANGE:  pg_num 128 size 3 would mean 1635 total pgs, which exceeds max 1500 (mon_max_pg_per_osd 250 * num_in_osds 6)

修改ceph配置文件

vim /etc/ceph/ceph.conf

[global]
mon_max_pg_per_osd
