Re: heartbeat problem???

Hi,

Thanks a lot for the reply.

But I am just wondering in case that heartbeat link is failure, if the
system would back to its normal working status after the heartbeat
link is restored? I mean back to the status of one master one slave.
In my tests, it seemed sometimes it won't, as indicated in my last
message, I got two master running. And we can't offord to restart the
whole system to make HA work again...

Any ideas?

Thanks!
