Max PXs per PV The maximum number of extents in a physical volume.
Max Ext Size (Mbytes) The maximum size of an extent in megabytes.
Min Unshare Unit (Kbytes) The minimum unshare unit size in kilobytes. This is only applicable to
volume group versions 2.2.
Max Unshare Unit (Kbytes) The maximum unshare unit size in kilobytes. This is only applicable to
volume group versions 2.2.
Max Snapshots per LV The maximum number of snapshots supported for a logical volume. This
is only applicable to volume group versions 2.2.
Max Snapshot Capacity The maximum snapshot capacity for a volume group. This is only applica-
ble to volume group versions 2.2.
Display with -l Option
For each volume group version to be displayed (one if
-V is specified, all if -V is omitted) lvmadm
displays the following:
• The list of volume groups that exist on the system, and
• The list of physical volumes belonging to each of the volume groups.
The LVM configuration displayed by this option is from data contained in the
/etc/lvmtab and
/etc/lvmtab_p files. The command fails if these files are missing or corrupt.
Compact Listing (-F Option)
The
-F option generates a compact and parsable listing of the command output in colon separated fields
formatted as key=value[,value...].
The
-F option is designed to be used by scripts. The resulting command output may be split across multi-
ple lines. The output may include new keys and/or values in the future. If a key is deprecated, its associ-
ated value is set to NAM (key=NAM).
Compact Listing for -t option
Below is a sample output:
vg_version=value :max_vg_size=value :max_lv_size=
value :
max_pv_size=value :max_vgs=value :max_lvs=value:
max_pvs=value :max_mirrors=value :max_stripes=
value :
max_stripe_size=
value :max_lx_per_lv=value :max_px_per_pv=value:
max_extent_size=

For volume group 2.2:
vg_version=value :max_vg_size=value
:max_lv_size=value :

Environment Variables
LANG determines the language in which messages are displayed.
If
LANG is not specified or is null, it defaults to "C" (see lang (5)).
If any internationalization variable contains an invalid setting, all internationalization variables default
