lvs produces formatted output about logical volumes.
See lvm for common options.
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.
Use with --separator to align the output columns.
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.
Comma-separated ordered list of columns. Precede the list with '+' to append
to the default selection of columns instead of replacing it.
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.
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:
Volume type: (m)irrored, (M)irrored without initial sync, (o)rigin,
(O)rigin with merging snapshot, (s)napshot, merging (S)napshot, (p)vmove,
(v)irtual, mirror (i)mage, mirror (I)mage out-of-sync, under (c)onversion
Permissions: (w)riteable, (r)ead-only
Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere, (i)nherited
This is capitalised if the volume is currently locked against allocation
changes, for example during pvmove (8).
State: (a)ctive, (s)uspended, (I)nvalid snapshot, invalid (S)uspended snapshot,
mapped (d)evice present without tables, mapped device present with (i)nactive table
Use default columns that emphasize segment information.
Comma-separated ordered list of columns to sort by. Replaces the default
selection. Precede any column with - for a reverse sort on that column.
Output columns as rows.
String to use to separate each column. Useful if grepping the output.
Produce output immediately without sorting or aligning the columns properly.
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.
