我试图分离

Amazon EBS Volume from an Instance,我无法弄清楚为什么文件系统无法找到/未安装.

在我的EBS卷上,附件信息显示：

(Instance1):/dev/sdh (attached)

(Instance1):/dev/sdo (attached)

(Instance1):/dev/sdo (attached)

(Instance1):/dev/sdj (attached)

(Instance1):/dev/sdi (attached)

(Instance1):/dev/sdn (attached)

(Instance1):/dev/sdm (attached)

(Instance1):/dev/sda1 (attached)

(Instance1):/dev/sdl (attached)

在实例上运行fdisk -l,我得到：

试图卸下：

[root@ip-10-0-0-22 ~]# umount -d /dev/xvdm

umount: /dev/xvdm: not mounted

[root@ip-10-0-0-22 ~]# umount -d /dev/sdm

umount: /dev/sdm: not found

安装：

[root@ip-10-0-0-22 ~]# mount

如何删除底层文件系统？

Delete what underlying filesystems? Also, could you cut-and-paste the output of cat /proc/mdstat into your question? – MadHatter

[root@ip-10-0-0-22 ~]# cat /proc/mdstat
