LVM question here. Every time I make a new volume group (or perhaps LV) I get a /dev/dm-# file representing the "aggregate volume". I can then see that in the output of useful tools such as iostat.
My question is that I am looking at a system with dm-1 thru dm-6, with various PVs VGs and LVs. How can I map the various dm-#s to theses PVs, VGs and LVs?
PV Physical Volume VG Volume Group LV Logical Volume
(Please correct me if I am wrong too BTW) Thanks Much!
