You can view the current amount of disk space allocated for the operation of KUMA Core. If required, you can change the allocated disk space.
Viewing the currently allocated disk space
The commands for viewing the disk space do not affect the operation of the running services.
To view the disk space allocated for KUMA Core:
On the administrator host, run the following command:
./kdt invoke kuma --action getCorePvcSize
Changing the currently allocated disk space
The command changes the core_disk_request parameter. When you run the command, the KUMA Core service is stopped, the disk space is changed, and the service is restarted. The application updates the core_disk_request parameter only if the command is successfully completed.
You can only enlarge the current disk space. If you try to set a disk space value smaller than the current one, the command returns an error. In this case, the service does not stop.
If an error occurs after the service has already been stopped, the application tries to restart the service and keep the previous disk space value.
To change the disk space allocated for KUMA Core:
On the administrator host, run the following command:
./kdt invoke kuma --action setCorePvcSize --param core_disk_request=<value>
where <value> is new disk space size, for example 50Gi.
