Resize up compute and memory servers
Previous section: Resize standard and general purpose servers
This article shows you how to use the Cloud Control Panel to resize up a compute or memory server. Resizing a server changes the RAM and disk space allocation.
Note: You can only resize up compute and memory servers. You can’t resize them down.
Cloud Control Panel
Use the following steps to resize up your servers by using the Cloud Control Panel:
Log in to the Cloud Control Panel.
In the top navigation bar, click Select a Product > Rackspace Cloud.
Select Servers > Cloud Servers to view a list of your existing servers.
Click the gear icon next to the server that you want to resize, and then click Resize.
A pop-up window that lists your server size options displays.
Select a new server size, and then click Resize Server.
Note: Each server size has a different hourly cost for uptime, and the new cost goes into effect when the server resize process completes. This could mean that you pay different rates for the same server within a single billing cycle.
A notification displays prompting you to verify the changes that you made to your system resources and that there was no adverse impact to your server.
Verify that your server was resized correctly by remotely logging in to your server and verifying your system resources and file system integrity.
Note: Verification is an important step because it is the last chance you have to revert to the original size and cancel any changes to your server.
For a Linux® server, you can Secure Shell (SSH) to either the public or private Internet Protocol (IP) address and run the commands
df -h(hard disk usage) and
free -m(available RAM) to verify the changes.
For a Windows® server, additional steps are required to use additional space after resizing up. For more information, see Adding Disk Space After Resizing a Windows Server 2012 Cloud Server.
After you have verified the system resources and checked your file systems, select Confirm to confirm the resize or Revert to revert to the original size.
Confirming the resize changes the server status. The process is complete when the Status reads as Active, the Current Action is None, and the server has come back up from a reboot. Any web services that you had running might require you to log in and manually restart them.
Note: Resizes are automatically confirmed after 24 hours. Therefore, you cannot revert a server after you have manually confirmed the resize or until 24 hours have passed.
You can also use Pitchfork, an interactive web API application that enables you to interact quickly with Rackspace Cloud products to resize up your server. Use the following steps to resize up your server by using Pitchfork:
Navigate to Pitchfork and log in by using your cloud account username and API key.
Click the Cloud Servers icon to access the Cloud Servers page.
In the Region drop-down menu, select the region for the cloud server that you want to resize.
Scroll down to List Flavors and click Details. Enter limit=100 for the Filter parameter, and then click Send API Call.
Find the server that you want to resize and take note of the server UUID and flavor_id. You need these values for the Resize Server API call.
Scroll down to Resize Server and click Details. Enter the server_id (UUID) and flavor_id that you gathered in the previous step, and then click Send API Call.
The server status in the Cloud Control Panel should change to Resizing. After the operation is complete, you must verify the server resize by navigating to the Server Details page for the server that you resized.
