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.

Pitchfork

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.
