vgs − report information about volume groups
vgs [−a|−−all] [−−aligned] [−d|−−debug] [−h|−?|−−help] [−−ignorelockingfailure] [−−nameprefixes] [−−noheadings] [−−nosuffix] [−o|−−options [+]Field[,Field]] [−O|−−sort [+|-]Key1[,[+|-]Key2[,...]]] [−P|−−partial] [−−rows] [−−separator Separator] [−−unbuffered] [−−units hHbBsSkKmMgGtTpPeE] [−−unquoted] [−v|−−verbose] [−−version] [VolumeGroupName [VolumeGroupName...]]
vgs produces formatted output about volume groups.
See lvm for common options.
|
−−all |
List all volume groups. Equivalent to not specifying any volume groups. |
−−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.
Use -o vg_all to select all volume group columns.
Use -o help to view the full list of columns available.
Column names include: vg_fmt, vg_uuid, vg_name, vg_attr, vg_size, vg_free, vg_sysid, vg_extent_size, vg_extent_count, vg_free_count, max_lv, max_pv, pv_count, lv_count, snap_count, vg_seqno, vg_tags, vg_mda_count, vg_mda_free, and vg_mda_size, vg_mda_used_count.
Any "vg_" prefixes are optional. Columns mentioned in either pvs (8) or lvs (8) can also be chosen, but columns cannot be taken from both at the same time.
The vg_attr bits are:
|
1 |
Permissions: (w)riteable, (r)ead-only | ||
|
2 |
Resi(z)eable | ||
|
3 |
E(x)ported | ||
|
4 |
(p)artial: one or more physical volumes belonging to the volume group are missing from the system | ||
|
5 |
Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere, (i)nherited | ||
|
6 |
(c)lustered |
−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 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.
