импортировать VG из клонированных PV (Import a VG from cloned PVs)
Имя (Name)
vgimportclone — Import a VG from cloned PVs
Синопсис (Synopsis)
vgimportclone position_args
[ option_args ]
Описание (Description)
vgimportclone imports a VG from duplicated PVs, e.g. created by a
hardware snapshot of existing PVs.
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.

Параметры (Options)
-n|--basevgname String
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.
--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.
-h|--help
Display help text.
-i|--import
Import exported VGs. Otherwise VGs that have been exported
will not be changed (nor will their associated PVs).
--importdevices
Add devices to the devices file.
--lockopt String
Used to pass options for special cases to lvmlockd. See
lvmlockd(8) for more information.
--longhelp
Display long help text.
--nolocking
Disable locking.
--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'.
-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.
-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.
-y|--yes
Do not prompt for confirmation interactively but always
assume the answer yes. Use with extreme caution. (For
automatic no, see -qq.)
Переменные (Variables)
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.)
Переменные окружения (Environment variables)
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.
Примеры (Examples)
An original VG "vg00" has PVs "/dev/sda" and "/dev/sdb". The
corresponding PVs from a hardware snapshot are "/dev/sdc" and
"/dev/sdd". Rename the VG associated with "/dev/sdc" and
"/dev/sdd" from "vg00" to "vg00_snap" (and change associated
UUIDs).
vgimportclone --basevgname vg00_snap /dev/sdc /dev/sdd
