I solved my problem by making some hacktacular LSB script called "proxyres".
When I run a "service proxyres start", it SSHes and runs those restart commands
on the Proxy.
"service proxyres stop" simply exits with 0
and service proxyres status will netcat a port, 0 success 3 for failure.
It works..But hopefully there is a better method.
Here is what it looks like just for fun:
######
[root@mail-2 ~] cat /etc/init.d/proxyres
#!/bin/bash
# Restart the gosh darn Proxy LSB script
# chkconfig: 2345 80 05
# description: RTGDP Script
# RTGDP service controller script
case "$1" in
start)
ssh -i "/root/.ssh/proxy_identity" [email protected] 'service mta
restart'
;;
stop)
exit 0
;;
status)
if nc -vz 10.199.0.125 443 > /dev/null
then
echo "Server is up"
true
else
echo "Server is down"
exit 3
fi
;;
*)
echo "Usage: $0 {start|stop|status}"
exit 1
;;
esac
exit 0
######
Thanks,

Subject: [Pacemaker] Running remote SSH commands on another server?
Hello,
I am coming up short in my searches, but I don't know exactly what I am
searching for, hoping someone could point me in the right direction.
I have Pacemaker setup in active/passive on my Email server. The systems are in
sync using DRBD.
When there is a failure on node-1, everything fails over to node-2 and vice
versa. Everything actually works great.
I have the mail servers sitting behind a proxy, which is also the MTA. The
problem is, whenever the mailstores failover, there is a persistent connection
going from the Proxy -> Mailstore that breaks, and any incoming/outgoing mail
cannot be delivered even though the email server is back up. To fix this, I
need to SSH into the proxy and restart the proxy services to re-establish that
persistent connection.
Is there any way to include this as part of the failover in PaceMaker?
Something like:
<**Failure occured on mail-1**>
mount DRBD resources on mail-2
Assign the failover-ip to mail-2
Start the email server on mail-2
SSH into the proxy and restart the proxy service (From mail-2 using keys)
I am researching ways within the application itself to fix this problem, but no
luck yet.
Thanks for any help,
Mike
