Change cloud server configuration

Change cloud server configuration

In a cloud server, you can change the configuration and number of resources:

• select another fixed configuration line (except GPU Line);
• change the fixed configuration to an arbitrary configuration (except GPU Line);
• change the amount of resources in fixed or arbitrary configuration — vCPU, RAM, local disk size;
• change an arbitrary configuration to a fixed configuration.

A cloud server configuration with a local disk cannot be changed to a configuration without a local disk and vice versa.

Graphics processors can be added to servers of arbitrary configuration.

When you change the configuration, all data on the cloud server is saved.

You can use fixed configuration flavor or you can create a flavor. You can view the list of flavors using the command openstack flavor list or in the table The list of fixed configuration flavors in all pools;
   • <server> — Server ID or name. The list of servers can be viewed with the command openstack server list.
