  34. .Sh SYNOPSIS
    35. 

  35. To compile this driver into the kernel,
    36. 

  36. place the following line in your
    37. 

  37. kernel configuration file:
    38. 

  38. .Bd -ragged -offset indent

  42. Alternatively, to load the driver as a
    43. 

  43. module at boot time, place the following line in
    44. 

  44. .Xr loader.conf 5 :

  48. .Sh DESCRIPTION
    49. 

  49. The
    50. 

  50. .Nm
    51. 

  51. framework provides support for mapping Linux LVM volumes to GEOM providers.
    52. 

  52. .Nm
    53. 

  53. currently supports linear stripes with segments on one or more physical disks.
    54. 

  54. The parser is able to read LVM2 Text Format metadata, the logical volumes will
    55. 

  55. be assembled and made available under
    56. 

  56. .Pa /dev/linux_lvm/ .
    57. 

  57. The metadata is read-only, logical volumes cannot be allocated or resized.
    58.
