I have a Google Cloud Instance:

When i check the disk space with two different command it show:

df -H

Filesystem      Size  Used Avail Use% Mounted on  
/dev/sda2        11G  3.1G  7.5G  30% /  
devtmpfs        300M     0  300M   0% /dev  
tmpfs           308M     0  308M   0% /dev/shm  
tmpfs           308M   34M  274M  12% /run  
tmpfs           308M     0  308M   0% /sys/fs/cgroup  
/dev/sda1       210M   12M  198M   6% /boot/efi  
tmpfs            62M     0   62M   0% /run/user/1001

lsblk

 NAME   MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT  
 sda      8:0    0   30G  0 disk  
 ├─sda1   8:1    0  200M  0 part /boot/efi  
 └─sda2   8:2    0 29.8G  0 part /

Why i have these difference?

I want that my disk have all the 30G of space and not 11G.

Maybe the file system is not filling the whole partition. How did you create/modify the partition and file system? – sudodus Mar 20 '19 at 09:52
Assuming this is an ext* partition you can resize the disk with `resize2fs /dev/sda2` – Philip Couling Mar 20 '19 at 10:05

When i do `resize2fs /dev/sda2` i receive: `resize2fs 1.42.9 (28-Dec-2013) resize2fs: Bad magic number in super-block while trying to open /dev/sda2 Couldn't find valid filesystem superblock.` – Alessandro_Russo Mar 20 '19 at 10:45
Please don't do that online. – 炸鱼薯条德里克 Mar 20 '19 at 10:48
@炸鱼薯条德里克 What do you mean by online? – Alessandro_Russo Mar 20 '19 at 12:06
With filesystem mounted. But it doesn't seem to be the filesystem smaller than partition problem. Did you just re-write your partition table completely not using a proper partitioning tool? – 炸鱼薯条德里克 Mar 20 '19 at 12:10
@炸鱼薯条德里克i don't know, can you say to me how to check? – Alessandro_Russo Mar 20 '19 at 13:17
