[linux-lvm] Read/Write LV Extent Stats

[Robin Tan]

Hi,
lvdisplay -v command used to display number of reads and writes on LV extent.I'm on Redhat 6.2 and lvdisplay -v does not show that anymore.
Are there anyways to show those statistics or similar statistics.
lvmsar, lvmsadc give me output of "Command not implemented yet.".
Appreciate your help.
Rob
