Hi Dejan,

Well i  tried to configure sbd  on two nodes cluster.  it is not working
properly.  need your view here. In split-brain situation both nodes are
trying to stonith each other and they have written  "Reset" to each other's
slot also. (nodes name are tejas and toddy)

tejas:~ # sbd -d /dev/sdd list
0       tejas reset   toddy
1       toddy  reset   tejas

Syslog is also saying that they have reset each other successfully.

Feb 10 10:02:54 tejas stonithd: [9195]: info: Succeeded to STONITH the node
toddy: optype=RESET. whodoit: tejas

Feb 10 10:03:55 toddy stonithd: [9195]: info: Succeeded to STONITH the node
tejas: optype=RESET. whodoit: toddy

But both nodes didn't reset actually.  can you tell me why it happened.
