DESCRIPTION         top

       lvs produces formatted output about logical volumes.

OPTIONS         top

       See lvm(8) for common options.

       --aligned
              Use with --separator to align the output columns.

       --all  Include information in the output about internal Logical
              Volumes that are components of normally-accessible Logical
              Volumes, such as mirrors, but which are not independently
              accessible (e.g. not mountable).  The names of such Logical
              Volumes are enclosed within square brackets in the output.
              For example, after creating a mirror using lvcreate -m1
              --mirrorlog disk , this option will reveal three internal
              Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.

       --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).

       --configreport  ReportName
              Make any subsequent -o, --options, -O, --sort or -S, --select
              to apply for ReportName where ReportName is either 'lv' for
              command's main report or 'log' for log report.  If
              --configreport option is not used to identify a report, then
              command's main report is assumed. The log report is available
              only if enabled by log/report_command_log lvm.conf(5) setting
              or if --logonly option is used.

       -H ,  --history
              Include historical logical volumes in the output.  (This has
              no effect unless logical volumes were removed while the
              configuration setting metadata/record_lvs_history was
              enabled.)

       --logonly
              Suppress the lvs report itself and display only log report on
              output.

       --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(7) rules).

       --noheadings
              Suppress the headings line that is normally the first line of
              output.  Useful if grepping the output.

       --nosuffix
              Suppress the suffix on output sizes.  Use with --units (except
              h and H) if processing the output.

       -o, --options
              Comma-separated ordered list of columns.

              Precede the list with '+' to append to the current list of
              columns, '-' to remove from the current list of columns or '#'
              to compact given columns. The -o option can be repeated,
              providing several lists. These lists are evaluated from left
              to right.

              Use -o lv_all to select all logical volume columns, and -o
              seg_all to select all logical volume segment columns.

              Use -o help to view the full list of columns available.

              Column names include: chunk_size, convert_lv, copy_percent,
              data_lv, devices, discards, lv_attr, lv_host, lv_kernel_major,
              lv_kernel_minor, lv_kernel_read_ahead, lv_major, lv_minor,
              lv_name, lv_path, lv_profile, lv_read_ahead, lv_size, lv_tags,
              lv_time, lv_uuid, metadata_lv, mirror_log, modules, move_pv,
              origin, origin_size, pool_lv, raid_max_recovery_rate,
              raid_min_recovery_rate, raid_mismatch_count, raid_sync_action,
              raid_write_behind, region_size, segtype, seg_count,
              seg_pe_ranges, seg_size, seg_size_pe, seg_start, seg_start_pe,
              seg_tags, snap_percent, stripes, stripe_size, sync_percent,
              thin_count, transaction_id, zero.

              With --segments, any "seg_" prefixes are optional; otherwise
              any "lv_" prefixes are optional. Columns mentioned in vgs(8)
              can also be chosen.

              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.

                 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.

       -O, --sort
              Comma-separated ordered list of columns to sort by.  Replaces
              the default selection. Precede any column with '-' for a
              reverse sort on that column.

       --rows Output columns as rows.

       -S, --select Selection
              Display only rows that match Selection criteria. All rows are
              displayed with the additional "selected" column (-o selected)
              showing 1 if the row matches the Selection and 0 otherwise.
              The Selection criteria are defined by specifying column names
              and their valid values (that can include reserved values)
              while making use of supported comparison operators. See lvm(8)
              and -S, --select description for more detailed information
              about constructing the Selection criteria. As a quick help and
              to see full list of column names that can be used in Selection
              including the list of reserved values and the set of supported
              selection operators, check the output of lvs -S help command.

       --segments
              Use default columns that emphasize segment information.

       --separator Separator
              String to use to separate each column.  Useful if grepping the
              output.

       --unbuffered
              Produce output immediately without sorting or aligning the
              columns properly.

       --units hHbBsSkKmMgGtTpPeE
              All sizes are output in these units: (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.  Can also specify
              custom units e.g. --units 3M

       --unquoted
              When used with --nameprefixes, output values in the
              field=value pairs are not quoted.
