clone LVM disk to a larger disk
I'm using two HP Microservers with a Heartbeat1 cluster, drbd and kvm.
On one of these servers the systemdisk is a 160GB disk with LVM
configured, on the other node it's a 1TB disk. I'd like to have both
nodes with the same disk sizes (easier to configure imo)
Now I've got a 1TB disk which I would like to use instead of the 160GB
disk. My question: Can I just clone the small disk to the new large disk
and then resize the LV on it ? Does that work ? I would say yes, but
I've never done that, so I am not sure... ;)
Is there any advantage to use dd instead of Clonezilla, ReDo or
whatever ? Maybe dd is slower than the other tools, but other than that
there shouldn't be any issues, correct ?
