When called without the --cache option, pvscan lists PVs on the
system, like pvs(8) or pvdisplay(8).
When --cache is used, pvscan updates runtime lvm state on the
system, or with -aay performs autoactivation.
pvscan --cache device
If device is present, lvm records that the PV on device is online.
If device is not present, lvm removes the online record for the
PV. pvscan only reads the named device.
pvscan --cache
Updates the runtime state for all lvm devices.
pvscan --cache -aay device
Performs the --cache steps for the device, then checks if the VG
using the device is complete. If so, LVs in the VG are
autoactivated, the same as vgchange -aay vgname would do. (A
device name may be replaced with major and minor numbers.)
pvscan --cache -aay
Performs the --cache steps for all devices, then autoactivates any
complete VGs.
pvscan --cache --listvg|--listlvs device
Performs the --cache steps for the device, then prints the name of
the VG using the device, or the names of LVs using the device.
--checkcomplete is usually included to check if all PVs for the VG
or LVs are online. When this command is called by a udev rule,
the output must conform to udev rule specifications (see
--udevoutput.) The udev rule will use the results to perform
autoactivation.
Autoactivation of VGs or LVs can be enabled/disabled using
vgchange or lvchange with --setautoactivation y|n, or by adding
names to lvm.conf(5) activation/auto_activation_volume_list
See lvmautoactivation(7) for more information about how pvscan is
used for autoactivation.
Display PV information.

[ --version ]
-a|--activate y|n|ay
Auto-activate LVs in a VG when the PVs scanned have
completed the VG. (Only ay is applicable.)
--autoactivation String
Specify if autoactivation is being used from an event.
This allows the command to apply settings that are specific
to event activation, such as device scanning optimizations
using pvs_online files created by event-based pvscans.
--cache
Scan one or more devices and record that they are online.
--checkcomplete
Check if all the devices used by a VG or LV are present,
and print "complete" or "incomplete" for each listed VG or
LV. This option is used as a part of event-based
autoactivation, so pvscan will do nothing if this option is
set and event_activation=0 in the config settings.
--commandprofile String
The command profile to use for command configuration. See
lvm.conf(5) for more information about profiles.
--config String
Config settings for the command. These override lvm.conf(5)
settings. The String arg uses the same format as
lvm.conf(5), or may use section/field syntax. See
lvm.conf(5) for more information about config.
-d|--debug ...
Set debug level. Repeat from 1 to 6 times to increase the
detail of messages sent to the log file and/or syslog (if
configured).
--devices PV
Devices that the command can use. This option can be
repeated or accepts a comma separated list of devices. This
overrides the devices file.
--devicesfile String
A file listing devices that LVM should use. The file must
exist in /etc/lvm/devices/ and is managed with the
lvmdevices(8) command. This overrides the lvm.conf(5)
devices/devicesfile and devices/use_devicesfile settings.
--driverloaded y|n
If set to no, the command will not attempt to use device-
mapper. For testing and debugging.
-e|--exported
Only show PVs belonging to exported VGs.
-h|--help
Display help text.
--ignorelockingfailure
Allows a command to continue with read-only metadata
operations after locking failures.
--journal String
Record information in the systemd journal. This
information is in addition to information enabled by the
lvm.conf log/journal setting. command: record information
about the command. output: record the default command
output. debug: record full command debugging.
--listlvs
Print a list of LVs that use the device.
--listvg
Print the VG that uses the device.
--lockopt String
Used to pass options for special cases to lvmlockd. See
lvmlockd(8) for more information.
--longhelp
Display long help text.
-j|--major Number
The major number of a device.
--minor Number
The minor number of a device.
--nohints
Do not use the hints file to locate devices for PVs. A
command may read more devices to find PVs when hints are
not used. The command will still perform standard hint file
invalidation where appropriate.
--nolocking
Disable locking.
--noudevsync
Disables udev synchronisation. The process will not wait
for notification from udev. It will continue irrespective
of any possible udev processing in the background. Only use
this if udev is not running or has rules that ignore the
devices LVM creates.
-n|--novolumegroup
Only show PVs not belonging to any VG.
--profile String
An alias for --commandprofile or --metadataprofile,
depending on the command.
-q|--quiet ...
Suppress output and log messages. Overrides --debug and
--verbose. Repeat once to also suppress any prompts with
answer 'no'.
--reportformat basic|json
Overrides current output format for reports which is
defined globally by the report/output_format setting in
lvm.conf(5). basic 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.
json produces report output in JSON format. See
lvmreport(7) for more information.
-s|--short
Short listing format.
-t|--test
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 error messages in multi-stage
operations if a tool relies on reading back metadata it
believes has changed but hasn't.
--udevoutput
Command output is modified to be imported from a udev rule.
-u|--uuid
Show UUIDs in addition to device names.
-v|--verbose ...
Set verbose level. Repeat from 1 to 4 times to increase the
detail of messages sent to stdout and stderr.
--version
Display version information.
--vgonline
The first command to see a complete VG will report it
uniquely. Other commands to see the complete VG will
report it differently.
-y|--yes
Do not prompt for confirmation interactively but always
assume the answer yes. Use with extreme caution. (For
automatic no, see -qq.)
PV Physical Volume name, a device path under /dev. For
commands managing physical extents, a PV positional arg
generally accepts a suffix indicating a range (or multiple
ranges) of physical extents (PEs). When the first PE is
omitted, it defaults to the start of the device, and when
the last PE is omitted it defaults to end. Start and end
range (inclusive): PV[:PE-PE]... Start and length range
(counting from 0): PV[:PE+PE]...
String See the option description for information about the string
content.
Size[UNIT]
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: 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.)
See lvm(8) for information about environment variables used by
lvm. For example, LVM_VG_NAME can generally be substituted for a
required VG parameter.
