文档：Make an Amazon EBS volume available for use on Linux - Amazon Elastic Compute Cloud

1.简介

aws ec2默认只会对根卷分区并且挂载目录，下面的根卷分了三个区，并且挂载到目录

$ lsblk
NAME     MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
loop0      7:0    0 25.1M  1 loop /snap/amazon-ssm-agent/5656
loop1      7:1    0 55.5M  1 loop /snap/core18/2409
loop2      7:2    0 61.9M  1 loop /snap/core20/1518
loop3      7:3    0   47M  1 loop /snap/snapd/16010
loop4      7:4    0 79.9M  1 loop /snap/lxd/22923
xvda     202:0    0   20G  0 disk
├─xvda1  202:1    0 19.9G  0 part /
├─xvda14 202:14   0    4M  0 part
└─xvda15 202:15   0  106M  0 part /boot/efi
xvdb     202:16   0   40G  0 disk

另外挂载的数据卷，需要手动分区并且挂载
