Hi All

Yes, Johannes' s right.

I tested source disk is primary, target disk is secondary in the 0.9.2
version,
The two nodes are connected directly at 1 Gbps.

windrbd is a stack structure, so if you want to use a virtual disk (the
actual data is accessible)
Only primary can mount.

Thanks
Best regards
