步驟以下：

（1）找出異常的PG,而後找對對應的osd，在對應的主機上進行修復

[root@node140 /]# ceph osd tree
ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF
-1 8.71826 root default
-2 3.26935 host node140
0 hdd 0.54489 osd.0 up 1.00000 1.00000
1 hdd 0.54489 osd.1 up 1.00000 1.00000
2 hdd 0.54489 osd.2 up 1.00000 1.00000
3 hdd 0.54489 osd.3 up 1.00000 1.00000
4 hdd 0.54489 osd.4 up 1.00000 1.00000
5 hdd 0.54489 osd.5 up 1.00000 1.00000
-3 3.26935 host node141
12 hdd 0.54489 osd.12 up 1.00000 1.00000
13 hdd 0.54489 osd.13 up 1.00000 1.00000
14 hdd 0.54489 osd.14 up 1.00000 1.00000
15 hdd 0.54489 osd.15 down 1.00000 1.00000
16 hdd 0.54489 osd.16 up 1.00000 1.00000
17 hdd 0.54489 osd.17 up 1.00000 1.00000
-4 2.17957 host node142
6 hdd 0.54489 osd.6 up 1.00000 1.00000
9 hdd 0.54489 osd.9 up 1.00000 1.00000
10 hdd 0.54489 osd.10 up 1.00000 1.00000
11 hdd 0.54489 osd.11 up 1.00000 1.00000

##這個命令也行
[root@node140 /]# ceph osd find 11
{
"osd": 11,
"addrs": {
"addrvec": [
{
"type": "v2",
"addr": "10.10.202.142:6820",
"nonce": 24423
},
{
"type": "v1",
"addr": "10.10.202.142:6821",
"nonce": 24423
}
]
},
"osd_fsid": "1e977e5f-f514-4eef-bd88-c3632d03b2c3",
"host": "node142",
"crush_location": {
"host": "node142",
"root": "default"
}
}

（2）對應的問題osd 11 17 ，切換到該主機，停掉osd

[root@node142 ~]# systemctl stop ceph-osd@11

（3）將日誌刷入磁盤

[root@node142 ~]# ceph-osd -i 15 --flush-journal

（4）啓動osd

[root@node142 ~]# systemctl start ceph-osd@11

（5）修復pg

[root@node142 ~]# ceph pg repair 3.3e

###osd 17 也一樣進行修復####

（6）查看狀態

[root@node141 ~]# ceph health detailHEALTH_OK
