Resizing a EBS volume as data container in Rancher

I’m facing a problem with Rancher, I was using an EBS as data container but was filled then i resize that volume in AWS from 10G to 30G, and I restarted my EC2 instance (with RancherOS), and then i re runned my service but Rancher is still detecting that i have 10G instead of 30G

Normally for anything but the boot disk, you should be fine. You just need to run efsck and the mkfs.ext4 commands.
