Hi Anders,

I have gone through the "Spare SC" feature documentation. I am not able to 
understand how Spare SC feature will help in this case?
In my case, there is a connectivity loss between 2 physical servers which 
results into 2 opensaf cluster.
Now when the connectivity is restored, there is no way to restore the original 
state.

Thanks,
Nivrutti

No, the "spare SC" feature was introduced in OpenSAF 5.0 and doesn't exist in 
earlier versions of OpenSAF.

We are using opensaf 4.5.
Is this feature not available in 4.5?

Which version of OpenSAF are you using? A simple split-brain detection and 
recovery mechanism was added as part of the "spare SC" feature in OpenSAF 5.0.

Hi All,



In my opensaf cluster there are 2 controllers and 8 payloads (10 VMs) on two 
physical servers. 1 Controller and 4 payload resides on one physical server 
each.

There is a connectivity loss between 2 physical servers which results into 2 
different opensaf cluster with 2 Active controllers.



After some time connectivity is restored between 2 physical servers. Still 
there are 2 opensaf clusters with 2 Active Controllers.

Is there any parameter in opensaf which will auto-recover the state of the 
opensaf cluster to normal. i.e 1 Active Controller and 1 Standby controller 
with 8 payloads in single opensaf cluster.



Thanks,
