[Linux-cluster] incompatible configurations

[Konrads Smelkovs]

Hello,
I have two nodes connected to SAN(san1 and san2), and one that is not 
(eth1, for locking purposes).
I've set the fencing method to manual.
All three nodes run the same cluster configuration (same file). However 
when eth1 connects to san1 or san2 ,the other boxes display:
Aug  2 13:26:21 san1 lock_gulmd_core[2762]: Config CRC doesn't match. ( 
20681140 != 4177759411 )
Aug  2 13:26:21 san1 lock_gulmd_core[2762]: We gave them(cmsfe01) an 
error (1004:Incompatible configurations).
Aug  2 13:26:21 san1 lock_gulmd_core[2762]: Closing connection idx:4, 
fd:9 to 192.168.100.151

why?
P.S. This is for purely testing purposes.
