.SH NAME

vgimportclone \(em Import a VG from cloned PVs
.
.SH SYNOPSIS
.
\fBvgimportclone\fP \fIposition_args\fP
.br
    [ \fIoption_args\fP ]
.br
.
.SH DESCRIPTION
.
vgimportclone imports a VG from duplicated PVs, e.g. created by a hardware
snapshot of existing PVs.
.P
A duplicated VG cannot used until it is made to coexist with the original
VG. vgimportclone renames the VG associated with the specified PVs and
changes the associated VG and PV UUIDs.

.SH OPTIONS
.
.
.HP
\fB-n\fP|\fB--basevgname\fP \fIString\fP
.br
By default the snapshot VG will be renamed to the original name plus a
numeric suffix to avoid duplicate naming (e.g. 'test_vg' would be renamed
to 'test_vg1'). This option will override the base VG name that is
used for all VG renames. If a VG already exists with the specified name
a numeric suffix will be added (like the previous example) to make it unique.
.
.HP
\fB--commandprofile\fP \fIString\fP
.br
The command profile to use for command configuration.
See \fBlvm.conf\fP(5) for more information about profiles.
.
.HP
\fB--config\fP \fIString\fP
.br
Config settings for the command. These override \fBlvm.conf\fP(5) settings.
The String arg uses the same format as \fBlvm.conf\fP(5),
or may use section/field syntax.
See \fBlvm.conf\fP(5) for more information about config.
.
.HP
\fB-d\fP|\fB--debug\fP ...
.br
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).
.
.HP
\fB--devices\fP \fIPV\fP
.br
Devices that the command can use. This option can be repeated
or accepts a comma separated list of devices. This overrides
the devices file.
.
.HP
\fB--devicesfile\fP \fIString\fP
.br
A file listing devices that LVM should use.
The file must exist in \fI#DEFAULT_SYS_DIR#/devices/\fP and is managed
with the \fBlvmdevices\fP(8) command.
This overrides the \fBlvm.conf\fP(5) \fBdevices/devicesfile\fP and
\fBdevices/use_devicesfile\fP settings.
.
.HP
\fB--driverloaded\fP \fBy\fP|\fBn\fP
.br
If set to no, the command will not attempt to use device-mapper.
For testing and debugging.
.
.HP
\fB-h\fP|\fB--help\fP
.br
Display help text.
.
.HP
\fB-i\fP|\fB--import\fP
.br
Import exported VGs. Otherwise VGs that have been exported
will not be changed (nor will their associated PVs).
.
.HP
\fB--importdevices\fP
.br
Add devices to the devices file.
.
.HP
\fB--journal\fP \fIString\fP
.br
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.
.
.HP
\fB--lockopt\fP \fIString\fP
.br
Used to pass options for special cases to lvmlockd.
See \fBlvmlockd\fP(8) for more information.
.
.HP
\fB--longhelp\fP
.br
Display long help text.
.
.HP
\fB--nohints\fP
.br
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.
.
.HP
\fB--nolocking\fP
.br
Disable locking.
.
.HP
\fB--profile\fP \fIString\fP
.br
An alias for --commandprofile or --metadataprofile, depending
on the command.
.
.HP
\fB-q\fP|\fB--quiet\fP ...
.br
Suppress output and log messages. Overrides --debug and --verbose.
Repeat once to also suppress any prompts with answer 'no'.
.
.HP
\fB-t\fP|\fB--test\fP
.br
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.
.
.HP
\fB-v\fP|\fB--verbose\fP ...
.br
Set verbose level. Repeat from 1 to 4 times to increase the detail
of messages sent to stdout and stderr.
.
.HP
\fB--version\fP
.br
Display version information.
.
.HP
\fB-y\fP|\fB--yes\fP
.br
Do not prompt for confirmation interactively but always assume the
answer yes. Use with extreme caution.
(For automatic no, see -qq.)
.
.SH VARIABLES
.
.TP
.I 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): \fIPV\fP[\fB:\fP\fIPE\fP\fB-\fP\fIPE\fP]...
Start and length range (counting from 0): \fIPV\fP[\fB:\fP\fIPE\fP\fB+\fP\fIPE\fP]...
.TP
.I String
See the option description for information about the string content.
.TP
.IR 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:
.BR b | B
is bytes,
.BR s | S
is sectors of 512 bytes,
.BR k | K
is KiB,
.BR m | M
is MiB,
.BR g | G
is GiB,
.BR t | T
is TiB,
.BR p | P
is PiB,
.BR 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.
