Hi, alnhk
Thank you for posting the information. In deed it shows the cause of the problem.
In your first post you mentioned you have deleted /dev/xvda2 using fdisk. However, the parts I have highlighted in red, show that /dev/xvda2 is not deleted; it has a filesystem and it is mounted. In fact, it can not be deleted unless it is offline, because it is the root (/) of the OS filesystem and the operating system will not let you. If you delete that partition booting from another filesystem (like a live CD) you will be erasing the whole OS. I do not think that's what you want.
