Configure initial resource oversubscription¶
Available since MOSK 23.1
MOSK enables you to configure initial oversubscription
OpenStackDeployment custom resource. For configuration details
and oversubscription considerations, refer to
Configuring initial resource oversubscription.
By default, the following values are applied:
8.0for the number of CPUs
1.6for the disk space
1.0for the amount of RAM
In MOSK 22.5 and earlier, the effective default value of RAM allocation ratio is
Changing oversubscription configuration after deployment will only affect the newly added compute nodes and will not change oversubscription for already existing compute nodes. You can change oversubscription for existing compute nodes through the placement API as described in Change oversubscription settings for existing compute nodes.
