ceph常见问题处理：https://access.redhat.com/documentation/zh-cn/red_hat_ceph_storage/5/html/troubleshooting_guide/most-common-ceph-osd-errors

1、问题报错1：

health: HEALTH_WARN

1 monitors have not enabled msgr2

解决：ceph mon enable-msgr2

2、问题报错2：

health: HEALTH_WARN

            mons are allowing insecure global_id reclaim

解决：

ceph config set mon mon_warn_on_insecure_global_id_reclaim false

ceph config set mon mon_warn_on_insecure_global_id_reclaim_allowed false

3、问题报错3：

health: HEALTH_WARN

            application not enabled on 1 pool(s)

查看原因：

root@control ~(admin-openrc)]# ceph health detail

HEALTH_WARN application not enabled on 1 pool(s)

POOL_APP_NOT_ENABLED application not enabled on 1 pool(s)

    application not enabled on pool 'images'

    use 'ceph osd pool application enable <pool-name> <app-name>', where <app-name> is 'cephfs', 'rbd', 'rgw', or freeform for custom applications.

分析

运行ceph health detail命令发现是新加入的存储池test没有被应用程序标记

解决：

ceph osd pool application enable images rbd

4、问题报错：

[root@controller1 ~]# ceph -s

  cluster:

    id:     2af51d38-db90-4a57-a43d-ea9f6ebd7482

    health: HEALTH_ERR

分析:

Osd.8  状态发生了down状态，引发了pg损坏

解决：

[root@controller1 ~]# ceph pg repair 9.17

[root@controller1 ~]# ceph pg repair 9.12b
