### volumeSelector

LVMVolumeSelectorSpec matches disks with CEL.

  <tbody>
    <tr>
      <td>`match`</td>
      <td>Expression</td>
      <td>CEL expression matching a disk or partition to use as a physical volume.<br /><br />The expression is evaluated against each discovered volume with the<br />`volume` variable (the discovered volume) and, for whole disks, the<br />`disk` variable. Partitions (e.g. raw volumes) can be matched by their<br />partition label via `volume.partition_label`.</td>
