hi list
I have 3-node HA cluster. each node is xen domU on separate physical
server. I created fencing devices as described by Russell Coker
(http://etbe.coker.com.au/2007/06/24/xen-and-heartbeat/). so, I'm really
sure that stonith devices itself works, because:
1. monitor and start operations always success
2. "stonith -t external/xen -p 'domU sshacc' -T host" works perfect,
but. but when I'm imitate failure (ifconfig eth0 down) on resource
(ipaddr) owner, nothing occurs. I can see in logs on DC:
info: client tengine [pid: 25914] want a STONITH operation RESET to node
netsrv0.office.sigmatrans.ru.
info: Broadcasting the message succeeded: require others to stonith node
netsrv0.office.sigmatrans.ru.
info: te_fence_node:actions.c Executing reboot fencing operation (19) on
netsrv0.office.sigmatrans.ru (timeout=2500)
this three messages is repeating, until myhost.mydomain.ru will not
reboot. fencing config is in attach. will appreciate any help.
