4、ceph df 查看集群使用情况
# 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
# ceph osd lspools
<rados.Rados object at 0x100166a7258>
('mon', '')
0 rbd,1 pool1,2 pool2,
6、查看ceph monitor仲裁情况
# ceph quorum_status --format json-pretty
statauth
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
# ceph mon dump
statauth
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
# ceph osd stat
statauth
end auth
<rados.Rados object at 0x10006f77258>
('mon', '')
osdmap e277: 20 osds: 20 up, 20 in
flags sortbitwise
#
# ceph pg stat
statauth
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
# ceph osd lspools
statauth
end auth
<rados.Rados object at 0x1000fbd7258>
('mon', '')
0 rbd,1 pool1,2 pool2,
10 列出集群的认证密钥
# ceph auth list
statauth
end auth
<rados.Rados object at 0x10036697258>
('mon', '')
