lvs − report information about logical volumes
lvs [−−aligned] [−d|−−debug] [−h|−?|−−help] [−−ignorelockingfailure] [−−nameprefixes] [−−noheadings] [−−nosuffix] [−o|−−options [+]Field[,Field]] [−O|−−sort [+|-]Key1[,[+|-]Key2[,...]]] [−P|−−partial] [−−rows] [−−segments] [−−separator Separator] [−−unbuffered] [−−units hsbkmgtHKMGT] [−−unquoted] [−v|−−verbose] [−−version] [VolumeGroupName [VolumeGroupName...]]
lvs produces formatted output about logical volumes.
See lvm
for common options.
−−aligned
Use with −−separator to align the output columns.
−−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 default selection of columns instead of replacing it. Column names are: lv_uuid, lv_name, lv_attr, lv_major, lv_minor, lv_kernel_major, lv_kernel_minor, lv_size, seg_count, origin, snap_percent, copy_percent, move_pv, lv_tags, origin_size, segtype, stripes, stripesize, chunksize, seg_start, seg_size, seg_tags, devices, regionsize, mirror_log, modules.
With −−segments, any "seg_" prefixes are optional; otherwise any "lv_" prefixes are optional. Columns mentioned in vgs (8) can also be chosen. Use -o help to view the full list of fields available.
The lv_attr bits are:
|
1 |
Volume type: (m)irrored, (M)irrored without initial sync, (o)rigin, (p)vmove, (s)napshot, invalid (S)napshot, (v)irtual, mirror (i)mage, mirror (I)mage out-of-sync, under (c)onversion | ||
|
2 |
Permissions: (w)riteable, (r)ead-only | ||
|
3 |
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). | ||
|
4 |
fixed (m)inor | ||
|
5 |
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 | ||
|
6 |
device (o)pen |
−−segments
Use default columns that emphasize segment information.
−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. |
−−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 hsbkmgtHKMGT
All sizes are output in these units: (h)uman-readable, (s)ectors, (b)ytes, (k)ilobytes, (m)egabytes, (g)igabytes, (t)erabytes. Capitalise to use multiples of 1000 (S.I.) instead of 1024. Can also specify custom (u)nits e.g. −−units 3M
−−unquoted
When used with --nameprefixes, output values in the field=value pairs are not quoted.
