This is the sort of job
is meant to do
You need root access to both of the physical hardware nodes to do this (Or a host prepared to do this for you), but as @jhadley said, DD is all you need.
As long as you have root access to the node, yes.
The best way to do it is using block level syncing. dd will copy empty space as well.
That's what you want if you're restoring to another LV which is the same size
As long the LV is not smaller than it's original, there shouldn't be any problems.
Also, if you transfer the image over the network, you should pipe it to 'lzop -1' to shrink the image to what you actually use, instead of the LV size.

Thanks
Oh, I don't think I can reboot into Rescue ISO. Is it possible to run while system is running?
No
