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: {} 

   1

   
   # ...

   Copy to Clipboard Toggle word wrap

   1

   Accepted values are:

   • Not defining optionalCsiComponents.
   • Specifying optionalCsiComponents field with an empty value ([]) or a single empty string element ([""]).

   • Specifying optionalCsiComponents with one of the accepted values which are 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" 

   1

   
   # ...

   Copy to Clipboard Toggle word wrap

   1

   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

   Copy to Clipboard Toggle word wrap
   Note

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