Hello,

> You can do data replication over the network (RAID-1 over network) . 
> DRBD (www.drbd.org) is the right solution for you . It will work with 
> OCFv2 also .

well, are you sure? According to this FAQ entry:
http://wiki.linux-ha.org/DRBD/FAQ#head-a39a43203ed93af71065d2a7b36b0db089207cbd

According to this, DRBD does not allow concurrent writes from different 
nodes.

Or you mean something like doing DRBD for backing the data up and 
iSCSI/GNBD/NBD/ENBD for actually sharing the DRBD device?

RAID-1 over network is a good idea, but I need some, that is 
cluster-aware (because of write ordering) and allows writes from all 
nodes...

Or am I completely wrong here?
