  • ceph使用问题积累

    1、HEALTH_WARN:pools have too many placement groups

    [root@k8s-master ~]# ceph -s
      cluster:
        id:     627227aa-4a5e-47c1-b822-28251f8a9936
        health: HEALTH_WARN
                2 pools have too many placement groups
                mons are allowing insecure global_id reclaim
    
    [root@k8s-master ~]# ceph health detail
    HEALTH_WARN 2 pools have too many placement groups; mons are allowing insecure global_id reclaim
    POOL_TOO_MANY_PGS 2 pools have too many placement groups
    Pool cephfs_metadata has 128 placement groups, should have 16
    Pool cephfs_data has 128 placement groups, should have 32
    [root@k8s-master ~]# ceph osd pool autoscale-status
    POOL              SIZE TARGET SIZE RATE RAW CAPACITY  RATIO TARGET RATIO EFFECTIVE RATIO BIAS PG_NUM NEW PG_NUM AUTOSCALE
    cephfs_metadata  1350k              2.0       30708M 0.0001                               4.0    128         16 warn
    cephfs_data     194.8k              2.0       30708M 0.0000                               1.0    128         32 warn

    原因: 开启了  autoscale-status
    解决方法:
    [root@k8s-master ~]# ceph mgr module disable pg_autoscaler

    2、HEALTH_WARN: mons are allowing insecure global_id reclaim

    [root@k8s-master ~]# ceph -s
      cluster:
        id:     627227aa-4a5e-47c1-b822-28251f8a9936
        health: HEALTH_WARN
                mons are allowing insecure global_id reclaim

    解决方法:  禁用不安全模式
    [root@k8s-master ~]# ceph config set mon auth_allow_insecure_global_id_reclaim false
    [root@k8s-master ~]# ceph -s
      cluster:
        id:     627227aa-4a5e-47c1-b822-28251f8a9936
        health: HEALTH_OK
