I created an LV with: lvcreate --name testlv0 --size 100m --mirror 1 testvg lvs -o +devices LV VG Attr LSize Origin Snap% Move Log Copy% Devices testlv0 testvg mwi-a- 100.00M testlv0_mlog 100.00 testlv0_mimage_0(0),testlv0_mimage_1(0) Any other suggestion for a -o option? I tried stripes, segtype, seg_start, seg_size, seg_tags, regionsize, mirror_log and lvs --segments. I can't find an option for pvs that prints the allocation map, nor for vgs. Any suggestions?
