RE: [linux-lvm] determining lv from mount point

["Montgomery, Kendal L" <kendal montgomery qwest com>]

Well.. The reason I say to do it this way is because lvdisplay doesn't
seem to give an "error" code on return (it's always 0) when it's not a
logical volume.  It does display an error message that you'd have to
parse the output for a specific error message.

This should work for LVM, but not sure about LVM2 because I haven't
personally had a chance to play with it. It may work for both, but I'm
not sure.

Is using lvscan preferable to something like this
lvdisplay ${DEVICE} > /dev/null 2>&1

I'm currently using LVM, not LVM2 (sorry, I should have said that in the
first message).  Will this method work for LVM2 as well?

thanks,
