[linux-lvm] Questions on LVM2 and device mapper

[Alexey Shinkin]

Hi , All !
 
A couple of questions on LVM2 and device mapper :
 
1. How corresponds logical devices in DM and  logical volumes in LVM2 ?
  are they the same things ?
 
2. In LVM1 some I/O statistics were available for a LV (using ioctl we
could see reads/writes for
 each allocated PE in LV structure) . Is there such thing in LVM2 ?  How
can I get a  numbe of reads/writes for a LV ?
 
Thanks 
 
Alexey Shinkin
