If your storage volume has run out of space due to growing blockchains, you may use the following directions to resize the volume attached to your droplet.
CAUTION: Please follow this guide carefully as there are wallet files involved. In particular, don't run any commands DigitalOcean prompts you to run. Only run those found in the article.
As always, it is good policy to backup your wallet files before making changes to your droplet.
Checking current usage
You may verify the current usage of your volume with:
The volume is the partition which is mounted at /mnt/blockchains.
Increasing the volume size
Within DigitalOcean, navigate to your Volumes tab, click on the More link, then choose Resize volume.
Choose an appropriate size given the current consumption of the blockchains you host. Most coin wallets run in pruned mode, meaning they will consume a constant amount of space, however Ethereum should run with a full blockchain, which may grow more rapidly than expected.
Resizing the partion
In your server's terminal, run the following command to resize the volume so the server sees the additional space:
curl -sS https://raw.githubusercontent.com/naconner/lamascripts/master/updates/volumes/resize.sh | bash
Checking the result
Afterward running the above resizing script, check that the operation was succesul by viewing the available space on /mnt/blockchains:
After five minutes, you may verify that they have maintained five minutes of uptime and remain 'STARTED':
Now your volume is resized and your server and machine are running.
