First you have to select the EBS volume >> Actions >> Modify Volume . Now select the total volume that you want to increase to in the size section. Now click on the Modify button. Now finally do the below steps after login to the server for extending the additionally allocated space. # df -h >> This will show you the Filesystem like '/dev/xvda1'. Expand the modified partition using growpart (note that you need to add a space between the device name and the partition number): # sudo growpart /dev/xvda 1 # sudo growpart /dev/nvme0n1 1 >> for /dev/nvme0n1p1 A look at the lsblk output confirms that the partition /dev/xvda1 now fills the available space on the volume: # root@logserver:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT xvda 202:0 0 40G 0 disk └─xvda1 202:1 0 40G 0 part / To extend a Linux file system # resize2fs /dev/xvda1 # resize2fs /dev/nvme0n1p1 https://docs.amazonaws.cn/en_us/
