[ClusterLabs] reducing peer node death detection time

[Nekrasov, Alexander]

Hello,

The problem I'm facing: reducing the time between a node panic and the call to STONITH on the peer node in a two node cluster. Documentation points to the token value in corosync.conf

totem {
        version: 2
        secauth: off
        threads: 0
        token:   1000
        token_retransmits_before_loss_const: 1
        join:           1000
        consensus:      10000
        interface {
                ringnumber: 0
                bindnetaddr: 128.221.255.100
                mcastaddr: 226.94.1.1
                mcastport: 5405
        }
}

Setting token to 1s results in around 5 seconds from real node death to STONITH call on surviving node. Further reduction down to 100ms doesn't seem to have any effect. Is there a way to further reduce this delay?

Thanks,
Alexander
