LVM which physical device
 

Hello,

I'm sure this is an easy question. How do I determine what physical device is connected to a volume or group?

I installed RH AS4 and it created volumes so that a df -h looks like
/dev/mapper/VolGroup_ID_21728-LogVol4 /usr
I want to know what /dev/sd? is connected to the above, how do I find this out. I tried an lvdisplay and a vgdisplay to no effect.

I have been reading documentation on the web that describes how to create and modify but not simply show the info I need.

If I do a "lvdisplay -v dev/mapper/VolGroup_ID_21728-LogVol4"
I get the error volume group mapper not found.

Thank you

Thanks, that worked :)
