I'm doing something similar: adopting a xen/kvm fence we use for Cluster 
Suite to DRBD.  

I noticed that, if the fence handler returns 6 (peer refused to be 
outdated), the connection is of a state:

 1: cs:WFConnection ro:Primary/Unknown ds:UpToDate/DUnknown C s----
    ns:0 nr:0 dw:4096 dr:28 al:1 bm:3 lo:0 pe:0 ua:0 ap:0 ep:1 wo:b oos:0

Is this still frozen?  How does one know?  

Where can I find documentation for the string "s----" ?  I'm missing it 
if it is in http://www.drbd.org/users-guide/ch-admin.html#s-proc-drbd

Thanks...
