Summary0017659: AWS EC2 could not expand EBS volume when using Centos 8 AMI Offical
DescriptionI'm using Offical Centos public images in to launch EC2 instance, more detail I'm using T3.micro instant type. After I modified volume size in AWS console, I can see a new size has been show in lsblk output command:

[root@ip-10-135-3-109 centos]# lsblk
 nvme0n1 259:0 0 12G 0 disk
 ├─nvme0n1p1 259:1 0 1M 0 part
 └─nvme0n1p2 259:2 0 10G 0 part /

[root@ip-10-135-3-109 centos]# df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 367M 0 367M 0% /dev
tmpfs 396M 0 396M 0% /dev/shm
tmpfs 396M 11M 386M 3% /run
tmpfs 396M 0 396M 0% /sys/fs/cgroup
/dev/nvme0n1p2 10G 2.4G 7.7G 24% /
tmpfs 80M 0 80M 0% /run/user/1000

However, I could not extend the partition on the root volume

[root@ip-10-135-3-109 centos]# growpart /dev/nvme0n1 1
NOCHANGE: partition 1 is size 2048. it cannot be grown

If I reboot EC2, the instance can automatically extend the partition, but I don't want any downtime when expand EBS like this way. Any idea or what might causing this issue?
