Help with failover

[mark redding]

Hi Michael,

I tried doing a very similar thing (only difference was that I was
scp'ing the data between hosts) and experienced the same as you have.
It seems that the only way to retain status data is by using the nsca
server/client - and having the primary post its active check results
(either with a global event handler or by enabling obsessing (but
beware, I could not get event handlers to run when obsessing was
active)) to the secondary (with the secondary running the nsca daemon
and having passive checks enabled), having the secondary periodically
checking that the primary is running (using check_nagios) and having
the secondary enable active checks and notifications when it detects
that the primary is down (and subsequently disabling these once the
primary is detected)

regards,
Mark
