DESCRIPTION         top

       lvs produces formatted output about logical volumes.

OPTIONS         top

       See lvm(8) for common options.

              Use with --separator to align the output columns.

              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).

       --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.

              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).

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

              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, (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, (X)

              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: (p)artial, (r)efresh needed, (m)ismatches
                 exist, (w)ritemostly, (X) unknown.  (p)artial signifies
                 that one or more of the Physical Volumes this Logical
                 Volume uses is missing from the system.  (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.

              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.

              Use default columns that emphasize segment information.

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

              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

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