+.SH DESCRIPTION
+The LVM devices file lists devices that lvm can use.  The default file is
+/etc/lvm/devices/system.devices, and the lvmdevices(8) command is used to
+add or remove device entries.  If the file does not exist, or if lvm.conf
+includes use_devicesfile=0, then lvm will not use a devices file.
+
+To use a device with lvm, add it to the devices file with the command
+lvmdevices --adddev, and to prevent lvm from seeing or using a device,
+remove it from the devices file with lvmdevices --deldev.  The
+vgimportdevices(8) command adds all PVs from a VG to the devices file,
+and updates the VG metadata to include device IDs of the PVs.
+
+Commands adding new devices to the devices file necessarily look outside
+the existing devices file to find the devices to add.  pvcreate, vgcreate,
+and vgextend also look outside the devices file to create new PVs and add
+them to the devices file.
+
+LVM records devices in the devices file using hardware-specific IDs, such
+as the WWID, and attempts to use subsystem-specific IDs for virtual device
+types (which also aim to be as unique and stable as possible.)
+These device IDs are also written in the VG metadata.  When no hardware or
+virtual ID is available, lvm falls back using the unstable device name as
+the device ID.  When devnames are used, lvm performs extra scanning to
+find devices if their devname changes, e.g. after reboot.
+
+When proper device IDs are used, an lvm command will not look at devices
+outside the devices file, but when devnames are used as a fallback, lvm
+will scan devices outside the devices file to locate PVs on renamed
+devices.  A config setting search_for_devnames can be used to control the
+scanning for renamed devname entries.
+
+Related to the devices file, the new command option --devices <devnames>
+allows a list of devices to be specified for the command to use,
+overriding the devices file.  The listed devices act as a sort of devices
+file in terms of limiting which devices lvm will see and use.  Devices
+that are not listed will appear to be missing to the lvm command.
+    
+Multiple devices files can be kept in /etc/lvm/devices, which allows lvm
+to be used with different sets of devices, e.g. system devices do not need
+to be exposed to a specific application, and the application can use lvm on
+its own devices that are not exposed to the system.  The option
+--devicesfile <filename> is used to select the devices file to use with the
+command.  Without the option set, the default system devices file is used.
+
+Setting --devicesfile "" causes lvm to not use a devices file.
+
+With no devices file, lvm will use any device on the system, and applies
+the filter to limit the full set of system devices.  With a devices file,
+the regex filter is not used, and the filter settings in lvm.conf or the
+command line are ignored.  The vgimportdevices command is one exception
+which does apply the regex filter when looking for a VG to import.
+
+If a devices file exists, lvm will use it, even if it's empty.  An empty
+devices file means lvm will see no devices.
+
+If the system devices file does not yet exist, the pvcreate or vgcreate
+commands will create it if they see no existing VGs on the system.
+lvmdevices --addev and vgimportdevices will always create a new devices file
+if it does not yet exist.
+
+It is recommended to use lvm commands to make changes to the devices file to
+ensure proper updates.
+
+.SH USAGE
+Print devices in the devices file.

+Size is an input number that accepts an optional unit.

+UNIT represents other possible input units: \fBbBsSkKmMgGtTpPeE\fP.
+b|B is bytes, s|S is sectors of 512 bytes, k|K is KiB,

+vgimportdevices adds PVs from a VG to the devices file.  This is similar

+individually.  vgimportdevices will also update the VG metadata to include
+the device IDs of each PV.  vgimportdevices will create a new devices file
+if none exists.
+
+When a devices file is used, the regex filter is ignored, except in the case

+to import to the devices file.  Use vgimportdevices -a to import all VGs on a

+\fB--reportformat\fP \fBbasic\fP|\fBjson\fP
+.br
+Overrides current output format for reports which is defined globally by
+the report/output_format setting in lvm.conf.
+\fBbasic\fP is the original format with columns and rows.
+If there is more than one report per command, each report is prefixed
+with the report name for identification. \fBjson\fP produces report
+output in JSON format. See \fBlvmreport\fP(7) for more information.

+\fB-S\fP|\fB--select\fP \fIString\fP
+.br
+Select objects for processing and reporting based on specified criteria.
+The criteria syntax is described by \fB--select help\fP and \fBlvmreport\fP(7).
+For reporting commands, one row is displayed for each object matching the criteria.
+See \fB--options help\fP for selectable object fields.
+Rows can be displayed with an additional "selected" field (-o selected)
+showing 1 if the row matches the selection and 0 otherwise.
+For non-reporting commands which process LVM entities, the selection is
+used to choose items to process.

+\fB-t\fP|\fB--test\fP

+Run in test mode. Commands will not update metadata.
+This is implemented by disabling all metadata writing but nevertheless
+returning success to the calling function. This may lead to unusual

+back metadata it believes has changed but hasn't.

+.SH VARIABLES
+.HP
+\fIVG\fP
+.br
+Volume Group name.  See \fBlvm\fP(8) for valid names.

+\fITag\fP
+.br
+Tag name.  See \fBlvm\fP(8) for information about tag names and using tags
+in place of a VG, LV or PV.
+.HP
+\fISelect\fP
+.br
+Select indicates that a required positional parameter can
+be omitted if the \fB--select\fP option is used.
+No arg appears in this position.
+.HP
+\fIString\fP
+.br
+See the option description for information about the string content.
+.HP
+\fISize\fP[UNIT]
+.br
+Size is an input number that accepts an optional unit.
+Input units are always treated as base two values, regardless of
+capitalization, e.g. 'k' and 'K' both refer to 1024.
+The default input unit is specified by letter, followed by |UNIT.
+UNIT represents other possible input units: \fBbBsSkKmMgGtTpPeE\fP.
+b|B is bytes, s|S is sectors of 512 bytes, k|K is KiB,
+m|M is MiB, g|G is GiB, t|T is TiB, p|P is PiB, e|E is EiB.
+(This should not be confused with the output control --units, where
+capital letters mean multiple of 1000.)
+.SH ENVIRONMENT VARIABLES
+See \fBlvm\fP(8) for information about environment variables used by lvm.
+For example, LVM_VG_NAME can generally be substituted for a required VG parameter.
