--aligned
Use with --separator to align the output columns
-a|--all
Show information about internal LVs. These are components of
normal LVs, such as mirrors, which are not independently
accessible, e.g. not mountable.
--binary
Use binary values "0" or "1" instead of descriptive literal
values for columns that have exactly two valid values to
report (not counting the "unknown" value which denotes that
the value could not be determined).
--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
settings. The String arg uses the same format as lvm.conf, or
may use section/field syntax. See lvm.conf(5) for more
information about config.
--configreport log|vg|lv|pv|pvseg|seg
See lvmreport(7).
-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).
--driverloaded y|n
If set to no, the command will not attempt to use device-
mapper. For testing and debugging.
--foreign
Report/display foreign VGs that would otherwise be skipped.
See lvmsystemid(7) for more information about foreign VGs.
-h|--help
Display help text.
-H|--history
Include historical LVs in the output. (This has no effect
unless LVs were removed while lvm.conf
metadata/record_lvs_history was enabled.
--ignorelockingfailure
Allows a command to continue with read-only metadata
operations after locking failures.
--ignoreskippedcluster
Use to avoid exiting with an non-zero status code if the
command is run without clustered locking and clustered VGs are
skipped.
--logonly
Suppress command report and display only log report.
--longhelp
Display long help text.
--nameprefixes
Add an "LVM2_" prefix plus the field name to the output.
Useful with --noheadings to produce a list of field=value
pairs that can be used to set environment variables (for
example, in udev rules).
--noheadings
Suppress the headings line that is normally the first line of
output. Useful if grepping the output.
--nolocking
Disable locking.
--nosuffix
Suppress the suffix on output sizes. Use with --units (except
h and H) if processing the output.
-o|--options String
Comma-separated, ordered list of fields to display in columns.
String arg syntax is: [+|-|#]Field1[,Field2 ...] The prefix +
will append the specified fields to the default fields, - will
remove the specified fields from the default fields, and #
will compact specified fields (removing them when empty for
all rows.) Use -o help to view the list of all available
fields. Use separate lists of fields to add, remove or
compact by repeating the -o option: -o+field1,field2 -o-
field3,field4 -o#field5. These lists are evaluated from left
to right. Use field name lv_all to view all LV fields, vg_all
all VG fields, pv_all all PV fields, pvseg_all all PV segment
fields, seg_all all LV segment fields, and pvseg_all all PV
segment columns. See the lvm.conf report section for more
config options. See lvmreport(7) for more information about
reporting.
--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'.
--readonly
Run the command in a special read-only mode which will read
on-disk metadata without needing to take any locks. This can
be used to peek inside metadata used by a virtual machine
image while the virtual machine is running. It can also be
used to peek inside the metadata of clustered VGs when
clustered locking is not configured or running. No attempt
will be made to communicate with the device-mapper kernel
driver, so this option is unable to report whether or not LVs
are actually in use.
--reportformat basic|json
Overrides current output format for reports which is defined
globally by the report/output_format setting in lvm.conf.
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.
--rows
Output columns as rows.
--segments
Use default columns that emphasize segment information.
-S|--select String
Select objects for processing and reporting based on specified
criteria. The criteria syntax is described by --select help
and lvmreport(7). For reporting commands, one row is
displayed for each object matching the criteria. See
--options help 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.
--separator String
String to use to separate each column. Useful if grepping the
output.
--shared
Report/display shared VGs that would otherwise be skipped when
lvmlockd is not being used on the host. See lvmlockd(8) for
more information about shared VGs.
-O|--sort String
Comma-separated ordered list of columns to sort by. Replaces
the default selection. Precede any column with - for a reverse
sort on that column.
-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.
--trustcache
Avoids certain device scanning during command processing. Do
not use.
--unbuffered
Produce output immediately without sorting or aligning the
columns properly.
--units r|R|h|H|b|B|s|S|k|K|m|M|g|G|t|T|p|P|e|E
All sizes are output in these units: human-(r)eadable with '<'
rounding indicator, (h)uman-readable, (b)ytes, (s)ectors,
(k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes,
(p)etabytes, (e)xabytes. Capitalise to use multiples of 1000
(S.I.) instead of 1024. Custom units can be specified, e.g.
--units 3M.
--unquoted
When used with --nameprefixes, output values in the
field=value pairs are not quoted.
-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.)
VG
Volume Group name. See lvm(8) for valid names.
LV
Logical Volume name. See lvm(8) for valid names. An LV
positional arg generally includes the VG name and LV name,
e.g. VG/LV.
Tag
Tag name. See lvm(8) for information about tag names and
using tags in place of a VG, LV or PV.
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: bBsSkKmMgGtTpPeE.
b|B is bytes, s|S is sectors of 512 bytes, k|K is kilobytes,
m|M is megabytes, g|G is gigabytes, t|T is terabytes, p|P is
petabytes, e|E is exabytes. (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.
The lv_attr bits are:
1 Volume type: (C)ache, (m)irrored, (M)irrored without initial sync,
(o)rigin, (O)rigin with merging snapshot, (r)aid, (R)aid without
initial sync, (s)napshot, merging (S)napshot, (p)vmove, (v)irtual,
mirror or raid (i)mage, mirror or raid (I)mage out-of-sync, mirror
(l)og device, under (c)onversion, thin (V)olume, (t)hin pool,
(T)hin pool data, raid or pool m(e)tadata or pool metadata spare.
2 Permissions: (w)riteable, (r)ead-only, (R)ead-only activation of
non-read-only volume
3 Allocation policy: (a)nywhere, (c)ontiguous, (i)nherited,
c(l)ing, (n)ormal This is capitalised if the volume is currently
locked against allocation changes, for example during pvmove(8).
4 fixed (m)inor
5 State: (a)ctive, (h)istorical, (s)uspended, (I)nvalid snapshot,
invalid (S)uspended snapshot, snapshot (m)erge failed, suspended
snapshot (M)erge failed, mapped (d)evice present without tables,
mapped device present with (i)nactive table, thin-pool (c)heck
needed, suspended thin-pool (C)heck needed, (X) unknown
6 device (o)pen, (X) unknown
7 Target type: (C)ache, (m)irror, (r)aid, (s)napshot, (t)hin,
(u)nknown, (v)irtual. This groups logical volumes related to the
same kernel target together. So, for example, mirror images,
mirror logs as well as mirrors themselves appear as (m) if they
use the original device-mapper mirror kernel driver; whereas the
raid equivalents using the md raid kernel driver all appear as
(r). Snapshots using the original device-mapper driver appear as
(s); whereas snapshots of thin volumes using the new thin
provisioning driver appear as (t).
8 Newly-allocated data blocks are overwritten with blocks of
(z)eroes before use.
9 Volume Health, where there are currently three groups of
attributes identified:
Common ones for all Logical Volumes: (p)artial, (X) unknown.
(p)artial signifies that one or more of the Physical Volumes this
Logical Volume uses is missing from the system. (X) unknown
signifies the status is unknown.
Related to RAID Logical Volumes: (r)efresh needed, (m)ismatches
exist, (w)ritemostly.
(r)efresh signifies that one or more of the Physical Volumes this
RAID Logical Volume uses had suffered a write error. The write
error could be due to a temporary failure of that Physical Volume
or an indication that it is failing. The device should be
refreshed or replaced. (m)ismatches signifies that the RAID
logical volume has portions of the array that are not coherent.
Inconsistencies are detected by initiating a "check" on a RAID
logical volume. (The scrubbing operations, "check" and "repair",
can be performed on a RAID logical volume via the 'lvchange'
command.) (w)ritemostly signifies the devices in a RAID 1 logical
volume that have been marked write-mostly. (R)emove after reshape
signifies freed striped raid images to be removed.
Related to Thin pool Logical Volumes: (F)ailed, out of (D)ata
space, (M)etadata read only.
(F)ailed is set if thin pool encounters serious failures and hence
no further I/O is permitted at all. The out of (D)ata space is set
if thin pool has run out of data space. (M)etadata read only
signifies that thin pool encounters certain types of failures but
it's still possible to do reads at least, but no metadata changes
are allowed.
Related to Thin Logical Volumes: (F)ailed.
(F)ailed is set when related thin pool enters Failed state and no
further I/O is permitted at all.
10 s(k)ip activation: this volume is flagged to be skipped during
activation.
