--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 \fb-o vg_all to select all volume group columns. Use \fb-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. 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:
-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.
