如何在CLI中安装连接的EC2卷？

Question

I just recovered data from an ec2 snapshot and created a volume with the data, i also attached the volume to my working instance, but I have problems mounting the new volume. On ec2-describe-volumes, I do get the find new volume created. i-14305121 /dev/sdi

---

How do I mount this /dev/sdi on to a directory so that I can access the files on it? I tried mount /dev/sdi, but I got an error: mount: special device /dev/sdi does not exist.

On running lsblk from terminal, i get this

dev1@ip-10-244-164-7:/$ lsblk /dev/sdi
lsblk: /dev/sdi: not a block device
dev1@ip-10-244-164-7:/$ lsblk /dev/xvdi
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvdi 202:128  0   8G  0 disk

---

On running mount /dev/xvdi, I also get this error. Other details of fdisk, mtab are also given here:

Answer 1

I'm not sure if this is a good answer, try running:

lsblk /dev/sdi

And it may list partitions that exists on that drive like this:

sdi
|--sdi1
|--sdi2
|--sdi3

If you have something like sdi1 you can try to mount it:

mount /dev/sdi1 /your/folder/here

Hope it helps.

Answer 2

I think you should try

mount /dev/xvdi /your/folder

In EC2 devices are named differently from what they promise in AWS console. See EC2: EBS device id confusion (/dev/sdf vs. /dev/xvdf)
