Actually, no - you don't have to do a network sync. You can just write zeros on both sides. That allows you to: - prevent users from creating an inconsistent mirror - avoid the network traffic of the initial sync Preventing the network traffic seems to be the reason everyone asks for this. The only other reason I can see would be to avoid the disk I/O performance hit at startup (In a DR mode or some such), or to do an initial mirror with dd and sneakernet the initial sync. -- Carson
