I have the following situation:
Where I would like to extend the size of nvme0n1 from 8GB to 78 GB using the command line.
Adding also fdisk as requested in comments:
Any help is appreciated.
This looks like an AWS EC2 instance you are adding a new volume to. You started correctly by listing the available devices.
Then, you need to create a file system on the new device (use sudo file -s to check if there is a file system already) with:
sudo mkfs -t ext4 /dev/nvme0n1p1
Then, make a directory on where you want to mount it:
sudo mkdir /mydata
And mount it:
sudo mount /dev/nvme0n1p1 /mydata
Finally, add it to fstab for auto mounting by editing fstab (back it up first) using:
sudo nano /etc/fstab
with the info from:
sudo lsblk -o +UUID
Test by unmounting the file system and then mounting it again with the next commands:
sudo umount /mydata
sudo mount -a
Hope this helps.
