Resize partition on running Linux instance

Step 1: Add storage

As an example, we'll pick AWS and will add 5GB(60->65 GB).

Step 2: Resize physical partition

Use lsblk | grep -v loop to list all available disks and partitions

sudo growpart /dev/{device_label} {index} to resize partition

Step 3: Tell the system to use newly available space

sudo resize2fs /dev/{partition_label}

df -h / to check results
