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 number of reads/writes for a LV ?
Thanks
Alexey Shinkin
