In my EC2 instance, that is attached to a volume EBS of 100GB, I run this command:
[ec2-user ~]$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda 202:0 0 100G 0 disk
└─xvda1 202:1 0 8G 0 part /
Here is the file /etc/fstab:
UUID=ue9a1ccd-a7dd-77f8-8be8-08573456abctkv / ext4 defaults 1 1
I want to understand: why only the volume of 8GB has a mount point ? Also, is the fact of mounting a volume on root '/', means that all the content of root is being stored on EBS volume?
