Use all available disk space

Even if you have a large SSD installed, there are cases where Ubuntu only reports 200GB of total available space, causing the system to run out of disk space when syncing.

The error message is similar to:

Fatal: Failed to register the Ethereum service: write /var/lib/goethereum/geth/chaindata/383234.ldb: no space left on device

To address this issue, assuming you have an SSD that is larger than 200GB, expand the space allocation for the LVM by following these steps:

sudo lvdisplay # Check your logical volume size

sudo lvm # Attach the lvm console
lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv
lvextend -l +100%FREE -r /dev/ubuntu-vg/ubuntu-lv
exit

sudo resize2fs /dev/ubuntu-vg/ubuntu-lv
df -h # Check results

Congratulations! You're now using all available disk space on your staking machine 🥳
