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
