lvs is the LVM command to show all logical volumes available

lvs [--aligned] [-d/--debug] [-h/-?/--help] [--ignorelockingfailure] [--noheadings] 
    [--nosuffix] [-o/--options [+]Field[,Field]] [-O/--sort [+/-]Key1[,[+/-]Key2[,...]]]
    [-P/--partial] [--segments] [--separator Separator] [--unbuffered] [--units hsbkmgtHKMGT]
    [-v/--verbose] [--version] [VolumeGroupName [VolumeGroupName...]] 

options

--aligned Use with --separator to align the output columns.
--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. Column names are: lv_uuid, lv_name, lv_attr, lv_minor, lv_size, seg_count, origin, snap_percent (suppressed if no kernel driver), segtype, stripes, stripesize, chunksize, seg_start, seg_size. 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: (o)rigin, (s)napshot, (w)riteable, (r)eadonly, (c)ontiguous allocation, (n)ext free allocation, fixed (m)inor, (s)uspended, (a)ctive, 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.
--separator SEP Use string SEP 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
