Basic two node cman configuration

["Sridharan Ramaswamy (srramasw)" <srramasw@xxxxxxxxx>]

I'm trying to understand the basics of ccs/cman layer for a two-node configuration. I understand, from the docs, this is a special condition that need cman started with  two_node="1" and expected_votes="1". But I still have problem starting cman. It complains the votes = -1 and fails to start.

 

Jan 22 12:35:50 cfs1 cman: cman_tool: the two-node option requires exactly two nodes with one vote each and expected votes of 1 (votes=-1) failed

But if remove two_node setting from <cman two_node="1" expected_votes="1"> to <cman> it actually starts fine!! Not sure where it is getting votes = -1.

 

Is this some silly mistake on my part or a known issue?

 

TIA,

Sridharan
