CEPH状态查询命令汇总

1、ceph -s 查看集群状态

[root@admin-node ~]# ceph -s

     health HEALTH_WARN

            109 pgs degraded

            9 pgs recovering

            96 pgs recovery_wait

            109 pgs stuck unclean

            recovery 38892/105044 objects degraded (37.024%)

     monmap e1: 1 mons at {admin-node=192.168.13.171:6789/0}

2、ceph health  查看集群状态

[root@admin-node ~]# ceph health

HEALTH_WARN 104 pgs degraded; 7 pgs recovering; 93 pgs recovery_wait; 104 pgs stuck unclean; recovery 36306/105044 objects degraded (34.563%)


3、ceph osd tree  检查OSD的CRUSH map

[root@admin-node ~]# ceph osd tree

ID WEIGHT   TYPE NAME      UP/DOWN REWEIGHT PRIMARY-AFFINITY

-1 20.00000 root default

21  1.00000         osd.21      up  1.00000          1.00000

[root@admin-node ~]#


4、ceph df 查看集群使用情况

[root@admin-node ~]# ceph df

GLOBAL:

    SIZE       AVAIL      RAW USED     %RAW USED

    74484G     74060G         423G          0.57

POOLS:

    NAME      ID     USED       %USED     MAX AVAIL     OBJECTS

    rbd       0       6168M      0.01        36535G        1542

    pool1     1      89872M      0.18        36535G       22469

    pool2     2        111G      0.21        36535G       28510


5、查看ceph存储池

[root@node3 bin]# ceph osd lspools

<rados.Rados object at 0x100166a7258>

('mon', '')

0 rbd,1 pool1,2 pool2,


6、查看ceph monitor仲裁情况

[root@node3 ~]# ceph quorum_status --format json-pretty

stat  auth

end auth

<rados.Rados object at 0x10026787258>

('mon', '')

{

    "election_epoch": 4,

    "quorum": [

        0

    ],

    "quorum_names": [

        "admin-node"

    ],

    "quorum_leader_name": "admin-node",

    "monmap": {

        "epoch": 1,

        "fsid": "99f00338-a334-4f90-a579-496a934f25c0",

        "modified": "2016-09-22 04:34:19.863934",

        "created": "2016-09-22 04:34:19.863934",

        "mons": [

            {

                "rank": 0,

                "name": "admin-node",

                "addr": "192.168.13.171:6789\/0"

            }

        ]

    }

}


7、导出ceph monitor信息

[root@node3 ~]# ceph mon dump

stat  auth

end auth

<rados.Rados object at 0x10037cc7258>

('mon', '')

dumped monmap epoch 1

epoch 1

fsid 99f00338-a334-4f90-a579-496a934f25c0

last_changed 2016-09-22 04:34:19.863934

created 2016-09-22 04:34:19.863934

0: 192.168.13.171:6789/0 mon.admin-node


8、检查ceph monitor OSD 和PG状态

[root@node3 ~]# ceph osd stat

stat  auth

end auth

<rados.Rados object at 0x10006f77258>

('mon', '')

     osdmap e277: 20 osds: 20 up, 20 in

            flags sortbitwise

[root@node3 ~]#

[root@node3 ~]# ceph pg stat

stat  auth

end auth

<rados.Rados object at 0x1002f4f7258>

('mon', '')

v19994: 320 pgs: 320 active+clean; 2030 GB data, 658 GB used, 73826 GB / 74484 GB avail


9、列出ceph存储池

[root@node3 ~]# ceph osd lspools

stat  auth

end auth

<rados.Rados object at 0x1000fbd7258>

('mon', '')

0 rbd,1 pool1,2 pool2,


10 列出集群的认证密钥

[root@node3 ~]# ceph auth list

stat  auth

end auth

<rados.Rados object at 0x10036697258>

('mon', '')

installed auth entries:
