Volume group name

If you did not configure LVMS in an lvmd.yaml file placed in the /etc/microshift/ directory, MicroShift attempts to assign a default volume group (VG) dynamically by running the vgs command.

  • MicroShift assigns a default VG when only one VG is found.

  • If more than one VG is present, the VG named microshift is assigned as the default.

  • If a VG named microshift does not exist, LVMS is not deployed.

If there are no volume groups on the MicroShift host, LVMS is disabled.

If you want to use a specific VG, LVMS must be configured to select that VG. You can change the default name of the VG in the configuration file. For details, read the "Configuring the LVMS" section of this document.

You can change the default name of the VG in the configuration file. For details, read the "Configuring the LVMS" section of this document.

After MicroShift starts, you can update the lvmd.yaml to include or remove VGs. To implement changes, you must restart MicroShift. If the lvmd.yaml is deleted, MicroShift attempts to find a default VG again.
