步驟如下：
（1）找出異常的PG,然后找對對應(yīng)的osd，在對應(yīng)的主機上進(jìn)行修復(fù)
[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

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

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(yīng)的問題osd 11 17 ，切換到該主機，停掉osd
[root@node142 ~]# systemctl stop ceph-osd@11
（3）將日志刷入磁盤
[root@node142 ~]# ceph-osd -i 15 --flush-journal
（4）啟動osd
[root@node142 ~]# systemctl start ceph-osd@11
（5）修復(fù)pg
[root@node142 ~]# ceph pg repair 3.3e
###osd 17 也同樣進(jìn)行修復(fù)####
（6）查看狀態(tài)
[root@node141 ~]# ceph health detail
HEALTH_OK
