Automatic output compaction
If you look at the lvs output above, you can see that the report also contains fields for which there is no information to display (e.g. the columns under "Origin" and "Pool" heading - the "origin" and "pool_lv" fields). LVM can automatically compact report output so such fields are not included in final output. To enable this feature and to compact all fields, use report/compact_output=1 in your configuration.

# lvmconfig --type full report/compact_output
compact_output=1

# lvs
LV LSize Cpy%Sync
lvol1 4.00m 100.00
lvol0 4.00m

# lvs vg/lvol0
LV LSize
lvol0 4.00m

Alternatively, you can define which fields should be compacted by configuring report/compact_output_cols configuration setting (or -o|--options # command line option).

# lvmconfig --type full report/compact_output report/compact_output_cols
compact_output=0
compact_output_cols="origin"

# lvs
LV LSize Pool Cpy%Sync
lvol1 4.00m 100.00
lvol0 4.00m

# lvs vg/lvol0
LV LSize Pool
lvol0 4.00m

# lvs -o#pool_lv
LV LSize Origin Cpy%Sync
lvol1 4.00m 100.00
lvol0 4.00m

We will use report/compact_output=1 for subsequent examples.

Further formatting options
By default, LVM displays sizes in reports in human-readable form which means that the most suitable unit is used so it’s easy to read. You can use report/units configuration setting (or --units option directly on command line) and report/suffix configuration setting (or --nosuffix command line option) to change this.

# lvs --units b --nosuffix
LV LSize Cpy%Sync
lvol1 4194304 100.00
lvol0 4194304

If you want to configure whether report headings are displayed or not, use report/headings configuration settings (or --noheadings command line option).

# lvs --noheadings
lvol1 4.00m 100.00
lvol0 4.00m

In some cases, it may be useful to display report content as key=value pairs where key here is actually the field name. Use report/prefixes configuration setting (or --nameprefixes command line option) to switch between standard output and the key=value output. The key=value pair is the output that is suitable for use in scripts and for other tools to parse easily. Usually, you also don’t want to display headings with the output that has these key=value pairs.

# lvs --noheadings --nameprefixes
LVM2_LV_NAME=’lvol1’ LVM2_LV_SIZE=’4.00m’ LVM2_COPY_PERCENT=’100.00’
LVM2_LV_NAME=’lvol0’ LVM2_LV_SIZE=’4.00m’ LVM2_COPY_PERCENT=’’

To define whether quotation marks in key=value pairs should be used or not, use report/quoted configuration setting (or --unquoted command line option).

# lvs --noheadings --nameprefixes --unquoted
LVM2_LV_NAME=lvol1 LVM2_LV_SIZE=4.00m LVM2_COPY_PERCENT=100.00
LVM2_LV_NAME=lvol0 LVM2_LV_SIZE=4.00m LVM2_COPY_PERCENT=

For easier parsing, you can even transpose the report so each column now becomes a row in the output. This is done with report/output_as_rows configuration setting (or --rows command line option).

# lvs --noheadings --nameprefixes --unquoted --rows
LVM2_LV_NAME=lvol1 LVM2_LV_NAME=lvol0
LVM2_LV_SIZE=4.00m LVM2_LV_SIZE=4.00m
LVM2_COPY_PERCENT=100.00 LVM2_COPY_PERCENT=

Use report/separator configuration setting (or --separator command line option) to define your own field separator to use.

# lvs --noheadings --nameprefixes --unquoted --separator " | "
LVM2_LV_NAME=lvol1 | LVM2_LV_SIZE=4.00m | LVM2_COPY_PERCENT=100.00
LVM2_LV_NAME=lvol0 | LVM2_LV_SIZE=4.00m | LVM2_COPY_PERCENT=

If you are using your own separator, the columns in the output are not aligned by default. Use report/aligned configuration setting (or --aligned command line option) for LVM to add extra spaces in report to align the output properly.

# lvs --separator " | "
LV | LSize | Cpy%Sync
lvol1 | 4.00m | 100.00
lvol0 | 4.00m |

# lvs --separator " | " --aligned
LV | LSize | Cpy%Sync
lvol1 | 4.00m | 100.00
lvol0 | 4.00m |

Let’s display one one more field in addition ("lv_tags" in this example) for the lvs report output.

# lvs -o+lv_tags
LV LSize Cpy%Sync LV Tags
lvol1 4.00m 100.00
lvol0 4.00m tagA,tagB

The "LV Tags" column in the example above displays two list values, separated by "," character for LV lvol0. If you need different list item separator, use report/list_item_separator configuration setting its definition.

# lvmconfig --type full report/list_item_separator
list_item_separator=";"

# lvs -o+tags
LV LSize Cpy%Sync LV Tags
lvol1 4.00m 100.00
lvol0 4.00m tagA;tagB

But let’s still use the original "," character for list_item_separator for subsequent examples.

Format for any of time values displayed in reports can be configured with report/time_format configuration setting. By default complete date and time is displayed, including timezone.

# lvmconfig --type full report/time_format
time_format="%Y-%m-%d %T %z"

# lvs -o+time
LV LSize Cpy%Sync CTime
lvol1 4.00m 100.00 2016-08-29 12:53:36 +0200
lvol0 4.00m 2016-08-29 10:15:17 +0200

We can change time format in similar way as we do when using date(1) command or strftime(3) function (lvmconfig --type default --withcomments report/time_format will give you complete list of available formatting options). In the example below, we decided to use %s for number of seconds since Epoch (1970-01-01 UTC).

# lvmconfig --type full report/time_format
time_format="%s"

# lvs
LV Attr LSize Cpy%Sync LV Tags CTime
lvol1 rwi-a-r--- 4.00m 100.00 1472468016
lvol0 -wi-a----- 4.00m tagA,tagB 1472458517

The lvs does not display hidden LVs by default - to include these LVs in the output, you need to use -a|--all command line option. Names for these hidden LVs are displayed within square brackets.

# lvs -a
LV LSize Cpy%Sync
lvol1 4.00m 100.00
[lvol1_rimage_0] 4.00m
[lvol1_rmeta_0] 4.00m
[lvol1_rimage_1] 4.00m
[lvol1_rmeta_1] 4.00m
lvol0 4.00m

You can configure LVM to display the square brackets for hidden LVs or not with report/mark_hidden_devices configuration setting.

# lvmconfig --type full report/mark_hidden_devices
mark_hidden_devices=0

# lvs -a
LV LSize Cpy%Sync
lvol1 4.00m 100.00
lvol1_rimage_0 4.00m
lvol1_rmeta_0 4.00m
lvol1_rimage_1 4.00m
lvol1_rmeta_1 4.00m
lvol0 4.00m

It’s not recommended to use LV marks for hidden devices to decide whether the LV is the one to use by end users or not. Please, use "lv_role" field instead which can report whether the LV is "public" or "private". The private LVs are used by LVM only and they should not be accessed directly by end users.

# lvs -a -o+lv_role
LV LSize Cpy%Sync Role
lvol1 4.00m 100.00 public
lvol1_rimage_0 4.00m private,raid,image
lvol1_rmeta_0 4.00m private,raid,metadata
lvol1_rimage_1 4.00m private,raid,image
lvol1_rmeta_1 4.00m private,raid,metadata
lvol0 4.00m public

Some of the reporting fields that LVM reports are of binary nature. For such fields, it’s either possible to display word representation of the value (this is used by default) or numeric value (0/1 or -1 in case the value is undefined).

# lvs -o+lv_active_locally
LV LSize Cpy%Sync ActLocal
lvol1 4.00m 100.00 active locally
lvol0 4.00m active locally

We can change the way how these binary values are displayed with report/binary_values_as_numeric configuration setting.

# lvmconfig --type full report/binary_values_as_numeric
binary_values_as_numeric=1

# lvs -o+lv_active_locally
LV LSize Cpy%Sync ActLocal
lvol1 4.00m 100.00 1
lvol0 4.00m 1

Changing output format
LVM can output reports in different formats - use report/output_format configuration setting (or --reportformat command line option) to switch the report output format.

Currently, LVM supports these output formats:

- "basic" (all the examples we used above used this format),
- "json",
- "json_std".

For example:
# lvs -o lv_name,lv_size --reportformat json
{
"report": [
{
"lv": [
{"lv_name":"lvol1", "lv_size":"4.00m"},
{"lv_name":"lvol0", "lv_size":"4.00m"}
]
}
]
}

The json_std output format is more compliant with JSON standard and compared to the original json format:

- it does not use double quotes around numeric values,
- numeric values are always expressed as numbers, not reserved strings
representing them (this also means that report/binary_values_as_numeric=1
setting is forced)
- it uses ’null’ for undefined numeric values,
- it prints string list as proper JSON array of strings instead of a single string.

Note that some configuration settings and command line options have no effect with certain report formats. For example, with json or json_std output, it doesn’t have any meaning to use report/aligned (--aligned), report/noheadings (--noheadings), report/columns_as_rows (--rows) or report/buffered (--unbuffered). All these configuration settings and command line options are ignored if using the json or json_std report output format.

Selection
If you need to select only specific rows from report, you can use LVM’s report selection feature. If you call lvm -S help, you’ll get quick help on selection. The help contains list of all fields that LVM can use in reports together with its type enclosed in square brackets. The example below contains a line from lvs -S help.

# lvs -S help
...
lv_size - Size of LV in current units. [size]
...

This line tells you you that the "lv_size" field is of "size" type. If you look at the bottom of the help output, you can see section about "Selection operators" and its "Comparison operators".

# lvs -S help
...
Selection operators
-------------------
Comparison operators:
=~ - Matching regular expression. [regex]
!~ - Not matching regular expression. [regex]
= - Equal to. [number, size, percent, string, string list, time]
!= - Not equal to. [number, size, percent, string, string_list, time]
>= - Greater than or equal to. [number, size, percent, time]
> - Greater than. [number, size, percent, time]
<= - Less than or equal to. [number, size, percent, time]
< - Less than. [number, size, percent, time]
since - Since specified time (same as ’>=’). [time]
after - After specified time (same as ’>’). [time]
until - Until specified time (same as ’<=’). [time]
before - Before specified time (same as ’<’). [time]
...

Here you can match comparison operators that you may use with the "lv_size" field which is of type "size" - it’s =, !=, >=, >, <= and <. You can find applicable comparison operators for other fields and other field types the same way.

To demonstrate selection functionality in LVM, we will create more LVs in addition to lvol0 and lvol1 we used in our previous examples.

# lvs -o name,size,origin,snap_percent,tags,time
LV LSize Origin Snap% LV Tags CTime
lvol4 4.00m lvol2 24.61 2016-09-09 16:57:44 +0200
lvol3 4.00m lvol2 5.08 2016-09-09 16:56:48 +0200
lvol2 8.00m tagA,tagC,tagD 2016-09-09 16:55:12 +0200
lvol1 4.00m 2016-08-29 12:53:36 +0200
lvol0 4.00m tagA,tagB 2016-08-29 10:15:17 +0200

When selecting size and percent fields, we don’t need to use units. For sizes, default "m" (for MiB) is used - this is the same behaviour as already used for LVM commands when specifying sizes (e.g. lvcreate -L). For percent fields, "%" is assumed automatically if it’s not specified. The example below also demonstrates how several criteria can be combined together.

# lvs -o name,size,snap_percent -S ’size=8m’
LV LSize
lvol2 8.00m

# lvs -o name,size,snap_percent -S ’size=8’
LV LSize
lvol2 8.00m

# lvs -o name,size,snap_percent -S ’size < 5000k’
LV LSize Snap%
lvol4 4.00m 24.61
lvol3 4.00m 5.08
lvol1 4.00m
lvol0 4.00m

# lvs -o name,size,snap_percent -S ’size < 5000k && snap_percent > 20’
LV LSize Snap%
lvol4 4.00m 24.61

# lvs -o name,size,snap_percent \
-S ’(size < 5000k && snap_percent > 20%) || name=lvol2’
LV LSize Snap%
lvol4 4.00m 24.61
lvol2 8.00m

You can also use selection together with processing-oriented commands.

# lvchange --addtag test -S ’size < 5000k’
Logical volume vg/lvol1 changed.
Logical volume vg/lvol0 changed.
Logical volume vg/lvol3 changed.
Logical volume vg/lvol4 changed.

# lvchange --deltag test -S ’tags = test’
Logical volume vg/lvol1 changed.
Logical volume vg/lvol0 changed.
Logical volume vg/lvol3 changed.
Logical volume vg/lvol4 changed.

LVM can recognize more complex values used in selection criteria for string list and time field types. For string lists, you can match whole list strictly, its subset or intersection. Let’s take "lv_tags" field as an example - we select only rows which contain "tagA" within tags field. We’re using { } to denote that we’re interested in subset that matches. If the subset has only one item, we can leave out { }.

# lvs -o name,tags -S ’tags={tagA}’
LV LV Tags
lvol2 tagA,tagC,tagD
lvol0 tagA,tagB

# lvs -o name,tags -S ’tags=tagA’
LV LV Tags
lvol2 tagA,tagC,tagD
lvol0 tagA,tagB

Depending on whether we use "&&" (or ",") or "||" ( or "#") as delimiter for items in the set we define in selection criterion for string list, we either match subset ("&&" or ",") or even intersection ("||" or "#").

# lvs -o name,tags -S ’tags={tagA,tagC,tagD}’
LV LV Tags
lvol2 tagA,tagC,tagD

# lvs -o name,tags -S ’tags={tagA || tagC || tagD}’
LV LV Tags
lvol2 tagA,tagC,tagD
lvol0 tagA,tagB

To match the complete set, use [ ] with "&&" (or ",") as delimiter for items. Also note that the order in which we define items in the set is not relevant.

# lvs -o name,tags -S ’tags=[tagA]’

# lvs -o name,tags -S ’tags=[tagB,tagA]’
LV LV Tags
lvol0 tagA,tagB

If you use [ ] with "||" (or "#"), this is exactly the same as using { }.

# lvs -o name,tags -S ’tags=[tagA || tagC || tagD]’
LV LV Tags
lvol2 tagA,tagC,tagD
lvol0 tagA,tagB

To match a set with no items, use "" to denote this (note that we have output compaction enabled so the "LV Tags" column is not displayed in the example below because it’s blank and so it gets compacted).

# lvs -o name,tags -S ’tags=""’
LV
lvol4
lvol3
lvol1

# lvs -o name,tags -S ’tags!=""’
LV LV Tags
lvol2 tagA,tagC,tagD
lvol0 tagA,tagB

When doing selection based on time fields, we can use either standard, absolute or freeform time expressions in selection criteria. Examples below are using standard forms.

# lvs -o name,time
LV CTime
lvol4 2016-09-09 16:57:44 +0200
lvol3 2016-09-09 16:56:48 +0200

# lvs -o name,time -S ’time since "2016-09-09 16:57:30"’
LV CTime
lvol4 2016-09-09 16:57:44 +0200

# lvs -o name,time \
-S ’time since "2016-08-29" && time until "2016-09-09 16:55:12"’
LV CTime
lvol2 2016-09-09 16:55:12 +0200
lvol1 2016-08-29 12:53:36 +0200
lvol0 2016-08-29 10:15:17 +0200

# lvs -o name,time \
-S ’time since "2016-08-29" && time before "2016-09-09 16:55:12"’
LV CTime
lvol1 2016-08-29 12:53:36 +0200
lvol0 2016-08-29 10:15:17 +0200

Time operators have synonyms: ">=" for since, "<=" for until, ">" for "after" and "<" for "before".

# lvs -o name,time \
-S ’time >= "2016-08-29" && time <= "2016-09-09 16:55:30"’
LV CTime
lvol2 2016-09-09 16:55:12 +0200
lvol1 2016-08-29 12:53:36 +0200
lvol0 2016-08-29 10:15:17 +0200

# lvs -o name,time \
-S ’time since "2016-08-29" && time < "2016-09-09 16:55:12"’
LV CTime
lvol1 2016-08-29 12:53:36 +0200
lvol0 2016-08-29 10:15:17 +0200

Example below demonstrates using absolute time expression.

# lvs -o name,time --config report/time_format="%s"

lvol4 1473433064
lvol3 1473433008

LV CTime
lvol4 2016-09-09 16:57:44 +0200

Command log reporting
As described in categorization based on reporting facility section at the beginning of this document, both report-oriented and processing-oriented LVM commands can report the command log if this is enabled with log/report_command_log configuration setting. Just like any other report, we can set the set of fields to display (log/command_log_cols) and to sort by (log/command_log_sort) for this report.

# lvmconfig --type full log/report_command_log log/command_log_cols \
log/command_log_sort log/command_log_selection
report_command_log=1
command_log_cols="log_seq_num,log_type,log_context,log_object_type,
log_object_name,log_object_group,log_message,
log_errno,log_ret_code"
command_log_sort="log_seq_num"
command_log_selection="!(log_type=status && message=success)"

# lvs
Logical Volume
==============
LV LSize Cpy%Sync
lvol1 4.00m 100.00
lvol0 4.00m

Command Log
===========
Seq LogType Context ObjType ObjName ObjGrp Msg Errno RetCode

As you can see, the command log is empty (it contains only field names). By default, LVM uses selection on the command log report and this case no row matched the selection criteria, see also log report specifics section in this document for more information. We’re displaying complete log report in the example below where we can see that both LVs lvol0 and lvol1 were successfully processed as well as the VG vg they are part of.

# lvmconfig --type full log/command_log_selection
command_log_selection="all"

# lvs
Logical Volume
==============
LV LSize Cpy%Sync
lvol1 4.00m 100.00
lvol0 4.00m

Command Log
===========
Seq LogType Context ObjType ObjName ObjGrp Msg Errno RetCode
1 status processing lv lvol0 vg success 0 1
2 status processing lv lvol1 vg success 0 1
3 status processing vg vg success 0 1

# lvchange -an vg/lvol1
Command Log
===========
Seq LogType Context ObjType ObjName ObjGrp Msg Errno RetCode
1 status processing lv lvol1 vg success 0 1
2 status processing vg vg success 0 1

Handling multiple reports per single command
To configure the log report directly on command line, we need to use --configreport option before we start any -o|--options, -O|--sort or -S|--select that is targeted for log report.

# lvs -o lv_name,lv_size --configreport log -o log_object_type, \
log_object_name,log_message,log_ret_code
Logical Volume

The lvm fullreport, with or without log report, consists of several reports - the --configreport is also used to target particular subreport here.

Below is an extended example with lvm fullreport to illustrate combination of various options. The report output is in JSON format. Also, we configure "vg", "pvseg", "seg" and "log" subreport to contain only specified fields. For the "pvseg" subreport, we’re interested only in PV names having "sda" in their name. For the "log" subreport we’re interested only in log lines related to either "lvol0" object or object having "sda" in its name. Also, for the log subreport we define ordering to be based on "log_object_type" field.

# lvm fullreport --reportformat json \
--configreport vg -o vg_name,vg_size \
--configreport pvseg -o pv_name,pvseg_start \
-S ’pv_name=~sda’ \
--configreport seg -o lv_name,seg_start \
--configreport log -o log_object_type,log_object_name \
-O log_object_type \
-S ’log_object_name=lvol0 || \
log_object_name=~sda’

Report extensions for LVM shell
As already stated in log report coverage paragraph under log report specifics in this documentation, when using LVM shell the log report coverage is wider. There’s also special command designed to query last command’s log report in the LVM shell - the lastlog command.

The example below illustrates a situation where we called lvs command. After that, we inspected the log report with the lastlog, without any selection so all the log report is displayed on output. Then we called lastlog further, giving various selection criteria. Then we ran unknown LVM command "abc" for which the log report displays appropriate failure state.
