When I run ec2 instnce with aws official clearlinux image, there is an error on the disk partition and it is an error on all kinds of instances.

I didn’t do anything, but /dev/root is almost full.

You created an instance with only 1GB of storage (1M blocks of 1K == 1GB).

The solution is to create instances with more storage.
