I use the minimal Photon distribution and it seems the system disk is only around 8GB.
That fills up quickly when installing some humongous Docker containers :/
List usage
df -h |
Check available space on disk
fdisk -l |
Install Diskpart
tdnf install parted
Diskpart
parted |
Increase size
resizepart |
print free |
Reboot
reboot |
Resize filesystem
resize2fs /dev/sda2 |
df -h |
And a reboot just for good measure
