After creating a Block Storage volume in the Cloud Panel and assigning it to a server, Linux servers will need to be configured to access the new Block Storage. Learn how to add Block Storage to a Cloud Server with Linux.<\/p>\n\n\n\n
Connect to the server with SSH, then use the NOTE<\/strong> The Block Storage \ndevice will only need to be formatted the first time you use it.
