F16 Copy/Clone Logical Volume

[scott32746]

Hello,

I am looking to copy a LV that is on two disk. Not sure if I need to look at copy/cloning at the VG level.
I am looking to take the LV that is on two disk and copy it to a larger one disk drive for backup purpose and if need to bootup on it.

You can create a new file system on another drive and copy the files with

cp -a

Your operating system is on a different drive?

Thanks,

but I think copy command is not the best way to go.
