Hi All,
I don't know if I'm involved in a split brain situation on my new 
Proxmox4 with DRBD9 3 nodes, this is the output of drbd-overview:

root at mpve2:~# drbd-overview
   0:.drbdctrl/0      Connected(3*)                 Secondary(3*) 
UpTo(mpve2)/UpTo(mpve3,mpve1)
   1:.drbdctrl/1      Connected(3*)                 Secondary(3*) 
UpTo(mpve2)/UpTo(mpve3,mpve1)
100:vm-100-disk-1/0  Conn(mpve2,mpve3)/StAl(mpve1) 
Seco(mpve2)/Unkn(mpve1)/Prim(mpve3) 
UpTo(mpve2)/Inco(mpve1)/UpTo(mpve3)
101:vm-101-disk-1/0  Connected(3*)                 Secondary(3*) 
UpTo(mpve2)/UpTo(mpve3,mpve1)

I don't understand how to manual solve it.
Please help.
Thanks,
Michele
