I am trying to expand an EBS volume from 120GB to 200GB on an c5d.xlarge EC2 instance running Ubuntu. I am following this guide.
So far, I have created a snapshot of the current EBS volume and then expanded it to 200GB.
sudo lsblk
nvme1n1 259:0 0 93.1G 0 disk
nvme0n1 259:1 0 200G 0 disk
└─nvme0n1p1 259:2 0 120G 0 part /
Following the guide, I have tried to expand the nvme0n1p1 partition to 200GB:
sudo growpart /dev/nvme0n1p1 1
WARN: unknown label
failed [sfd_dump:1] sfdisk --unit=S --dump /dev/nvme0n1p1
sfdisk: /dev/nvme0n1p1: does not contain a recognized partition table
FAILED: failed to dump sfdisk info for /dev/nvme0n1p1
It seems the partition is not recognized.
I have also tried with resize2fs command, but it doesn't do anything:
sudo resize2fs /dev/nvme0n1p1
resize2fs 1.44.1 (24-Mar-2018)
The filesystem is already 31457019 (4k) blocks long. Nothing to do!
Any idea how can I make the partition to expand to the correct size?
Actually the growpart command was wrong. It must follow the syntax growpart path/to/device_name partition_number, so the right command is:
sudo growpart /dev/nvme0n1 1
