GEOM_LINUX_LVM(4)					   BSD Kernel Interfaces Manual 					 GEOM_LINUX_LVM(4)

NAME

     geom_linux_lvm -- GEOM based Linux LVM logical volume mapping

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   options GEOM_LINUX_LVM

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   geom_linux_lvm_load="YES"

DESCRIPTION

     The geom_linux_lvm framework provides support for mapping Linux LVM volumes to GEOM providers.  geom_linux_lvm currently supports linear
     stripes with segments on one or more physical disks.  The parser is able to read LVM2 Text Format metadata, the logical volumes will be
     assembled and made available under /dev/linux_lvm/.  The metadata is read-only, logical volumes cannot be allocated or resized.

EXAMPLES

     To view which geom_linux_lvm devices are available:

	   # geom linux_lvm list
	   Geom name: vg1
	   Providers:
	   1. Name: linux_lvm/vg1-home
	      Mediasize: 4294967296 (4.0G)
	      Sectorsize: 512
	      Mode: r0w0e0
	   2. Name: linux_lvm/vg1-logs
	      Mediasize: 4294967296 (4.0G)
	      Sectorsize: 512
	      Mode: r0w0e0
	   Consumers:
	   1. Name: ada0s1
	      Mediasize: 80023716864 (75G)
	      Sectorsize: 512
	      Mode: r0w0e0

GEOM_UZIP(4)                                               BSD Kernel Interfaces Manual                                               GEOM_UZIP(4)

NAME

     geom_uzip -- GEOM based compressed disk images

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

           options GEOM_UZIP

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

           geom_uzip_load="YES"

DESCRIPTION

     The geom_uzip framework provides support for compressed read only disk images.  This allows significant storage savings at the expense of a
     little CPU time on each read.  Data written in the GEOM label area allows geom_uzip to detect compressed images which have been created with
     mkuzip(8) and presented to the kernel as a logical disk device via md(4).  geom_uzip creates a unique md#.uzip device for each image.

     The geom_uzip device is subsequently used by the FreeBSD kernel to access the disk images.  The geom_uzip driver does not allow write opera-
     tions to the underlying disk image.  To check which md(4) devices match a given geom_uzip device:

           # geom uzip list
           Geom name: md1.uzip
           Providers:
           1. Name: md1.uzip
              Mediasize: 22003712 (21M)
              Sectorsize: 512
              Mode: r1w0e1
           Consumers:
           1. Name: md1
              Mediasize: 9563648 (9.1M)
              Sectorsize: 512
              Mode: r1w0e1
