锐捷上网行为管理硬盘故障，锐捷超融合服务器硬盘故障

锐捷上网行为管理硬盘故障，锐捷超融合服务器硬盘故障7 1.81360 osd.7 up 1.00000 1.000002 1.81360 osd.2 up 1.00000 1.00000ID WEIGHT TYPE NAME UP/DOWN REWEIGHT PRIMARY-AFFINITY-1 21.76318 root default-2 5.44080 host node-4

我的思路是这样的，首次出现故障是服务器其中一个节点01号硬盘亮红灯，这台超融合服务器一共有4个节点，每个节点都可以独立登录控制。

服务器故障灯

登录节点后发现硬盘的OSD.8已经是down其它为UP，又因为是超融合服务器硬盘内置看不到，无法确定这个故障硬盘在节点的哪个盘

[root@node-1 ~]# ceph osd tree

ID WEIGHT TYPE NAME UP/DOWN REWEIGHT PRIMARY-AFFINITY

-1 21.76318 root default

-2 5.44080 host node-4

2 1.81360 osd.2 up 1.00000 1.00000

7 1.81360 osd.7 up 1.00000 1.00000

10 1.81360 osd.10 up 1.00000 1.00000

1 1.81360 osd.1 up 1.00000 1.00000

5 1.81360 osd.5 up 1.00000 1.00000

11 1.81360 osd.11 up 1.00000 1.00000

-4 5.44080 host node-1

3 1.81360 osd.3 up 1.00000 1.00000

4 1.81360 osd.4 up 1.00000 1.00000

8 1.81360 osd.8 down 0 1.00000

-5 5.44080 host node-3

0 1.81360 osd.0 up 1.00000 1.00000

6 1.81360 osd.6 up 1.00000 1.00000

9 1.81360 osd.9 up 1.00000 1.00000

所以得找出故障硬盘OSD.8的硬盘序列号

继续执行lsblk显示

sdc

sdc1

8:32 0 1.8T 0 disk

8:33 0 1.8T 0 part /var/lib/ceph/osd/ceph-8

确定osd.8在SDC上面

查询SDC盘

[root@node-1 ~]# smartctl -i /dev/sdc

确认硬盘型号和序列号（下划线）

到这一步坏盘已经找出来了，但是具体怎么去更换不敢乱动，有大神指教下的吗？关注留言后续处理情况。
