线上发现L版本一个OSD down，不确定是否磁盘故障，之前的filestore排查起来比较熟，换成Bluestore以后，有些细节上的操作不一样，因为用到的是SSD，所以有了这篇排查文档。
排查过程
定位故障节点
代码语言：javascript复制[root@demo-host ceph]# ceph osd tree|grep down
20 1.00000 osd.20 down 0 1.00000
[root@demo-host ceph]# ceph osd find 20
{
"osd": 20,
"ip": "192.168.8.124:6800/1298894",
"osd_fsid": "a99bc25c-4cf4-5429-9171-4084555af14b",
"crush_location": {
"host": "demo-host-ssd",
"media": "site1-rack1-ssd",
"mediagroup": "site1-ssd",
"root": "default"
}
}登录到上面的192.168.8.124，执行命令"dmesg -T"，发现有dm-0设备发生io错误
