Chapter 6. Disabling the LVMS CSI provider or CSI snapshot

Procedure

1. Disable installation of the CSI snapshot controller by entering the optionalCsiComponents value under the storage section of the MicroShift configuration file in /etc/microshift/config.yaml:

   # ...
     storage: {}
   # ...

   where:

   storage

   Specifies the storage details. You can choose to not define optionalCsiComponents. If you do specify the optionalCsiComponents field, valid values include: an empty value ([]) or a single empty string element ([""]), snapshot-controller, or none. A value of none is mutually exclusive with all other values.

   Note

   If the optionalCsiComponents value is empty or null, MicroShift defaults to deploying snapshot-controller.

2. After the optionalCsiComponents field is specified with a supported value in the config.yaml, start MicroShift by running the following command:

   $ sudo systemctl start microshift

   Note

   MicroShift does not redeploy the disabled components after a restart.

Procedure

1. Disable installation of the CSI driver by entering the driver value under the storage section of the MicroShift configuration file in /etc/microshift/config.yaml:

   # ...
     storage
      driver:
      - "none"
   # ...

   where:

   storage.driver.none

   Specifies the driver to disable. Valid values are none or lvms.

   Note

   By default, the driver value is empty or null and LVMS is deployed.

2. Start MicroShift after the driver field is specified with a supported value in the /etc/microshift/config.yaml file by running the following command:

   $ sudo systemctl enable --now microshift

   Note

   MicroShift does not redeploy the disabled components after a restart operation.
