报错如下：

Ceph Reduced data availability: 1 pg inactive pg 1.0 is stuck inactive for 9d, current state unknown, last acting []

问题示意：

1个pg无法使用，

修复流程：

直接使用如下查看故障的pg

[root@storage-ceph01 ~]# ceph pg dump_stuck inactive
ok
PG_STAT  STATE    UP  UP_PRIMARY  ACTING  ACTING_PRIMARY
1.0      unknown  []          -1      []              -1

接下来请求gp测试

[root@storage-ceph01 ~]# ceph pg 1.0 query
Error ENOENT: i don‘t have pgid 1.0

重建pg

[root@storage-ceph01 ~]# ceph osd force-create-pg 1.0 --yes-i-really-mean-it
pg 1.0 now creating, ok

file

验证pg状态

[root@storage-ceph01 ~]# ceph pg 1.0 query | head
{
"snap_trimq": "[]",
"snap_trimq_len": 0,
"state": "active+clean",
"epoch": 100,
"up": [
    3,
    0,
    1
],

查看ceph状态

[root@storage-ceph01 ~]# ceph -s
