Hi,

for fallback reasons of an existing server with software-raid5 I would like to 
install a raid1 via enbd to another system of this raid5-device.

scheme-1:
server1(software-raid5)-->raid1-->enbd-->fall-back server(hardisk or 
software-raid)

scheme-2:
server1(software-raid5)-->enbd-->fall-back-server(hardisk)--raid1

I guess that scheme-2, so exporting a mdX-device via enbd and importing this 
device on the fallback-server and mirroring it via raid1 to another 
hardisk-partition should work anyway.

But whats about scheme-1 in general ? Or in scheme-2 if one would like to put 
the the raid1 to another software-raid5 ?

Thanks in advance,
	Bernd
