I have a Amazon Web Services EC2 Debian 8.0 instance with an Elastic Block Storage (EBS) volume of 35GB. fdisk correctly shows the size but my root partition is still at 7.8G, although I tried to execute resize2fs.

Partition table entries are not in disk order.
As you see, the resize2fs does not have effect. I also cannot create a swap partition with more space than 1M.
This problem occurs on all my instances. Although they all have 30-35GB EBS volumes, I cannot resize them and they stay at 8GB. When I attach just an additional volume besides the root mounted one, it works fine.
Can you help me?
