Você pode usar o comando lvs com campos adicionais para exibir o layout LV, incluindo o número de distribuições. Por exemplo, 3 LVs aqui com listras usadas em conjunto com raid, espelho e layout listrado:
# lvs -o+lv_layout,stripes
LV VG Attr LSize Log Cpy%Sync Layout #Str
lvol0 vg rwi-a-r--- 8.00m 100.00 raid,raid10 4
lvol1 vg mwi-a-m--- 8.00m [lvol1_mlog] 100.00 mirror 2
lvol2 vg -wi-a----- 8.00m striped 2
Se quiser ver ainda mais, incluindo os LVs internos usados para construir o LV de nível superior (e seus layouts exatos), você pode usar:
#lvs -a -o+lv_layout,lv_role,stripes,devices
LV VG Attr LSize Log Cpy%Sync Layout Role #Str Devices
