You can specify a value between \"0\" and \"40\" to accommodate the possible number of new Instance Manager pods during upgrades. The default value is \"12\". **Caution**: [1] When the value is \"0\", CPU requests are removed from the spec of Instance Manager pods. [2] A new set of Instance Manager pods must be deployed when Longhorn is upgraded. If the available CPUs are not sufficient for the new pods, you must detach the volumes using the oldest Instance Manager pods so that Longhorn can automatically clean up the old pods and release the CPU resources. Once completed, the new pods with the latest Instance Manager image are launched. [3] This global setting is not applied to nodes with a specified value for the \"InstanceManagerCPURequest\" field. [4] After this setting is configured, Instance Manager pods on all nodes that use this setting are automatically restarted. **Do not change this setting while volumes are still attached.**"
