How to add a Volume to EC2 Instance?

Go to EC2 console to create the volume and attach it to the instance, and then we’ll mount the volume to make it available.

– under Elastic Block Store, click Volumes.
– Click on Create Volume – Select the General Purpose (SSD) volume type.
– Wait for your Volume to be available.
– Right click on it and select Attach Volume, Select the instance and specify an unused device name say /dev/xvdk

For making it available follow these steps:

[ec2-user ~]$ lsblk
NAME    MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
xvdk    202:80   0   22G  0 disk
xvda1   202:1    0    8G  0 disk /

here xvdk device is not mounted.

To Mount it – mkfs -t ext4 /dev/xvdk
# mkdir /mnt/space
# mount /dev/xvdf /mnt/space

Voila, You just added the volume to the system.

To check it, df -h

[ec2-user ~]$ df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/xvda1            7.9G  1.1G  6.8G  14% /
tmpfs                 298M     0  298M   0% /dev/shm
/dev/xvdk              22G     0   22G   0% /mnt/space
