what happens if you execute /etc/init.d/apache2 without any parameter?

what dies "file -k /etc/init.d/apache2" show?

why do you use lsb instead of the ocf:heartbeat:apache?

cheers,

Hi Raoul,

I don't use ocf:heartbeat:apache because of my special configuration:

apache is active on both nodes, the access is via haproxy, we have an url http://localhost:80 which accesses the local apache via ssl and delivers a static page (returning a fix text).
So if we switch over, the stop action does an apache_force_reload and sets the current node to standby. The new active node performs an apache_start (to be sure apache is running) and a force_reload to
establish the virtual ips. /etc/init.d/apache2 without any parameter gives no output. The output of file -k /etc/init.d/apache2 gives /etc/init.d/apache2: ASCII English text

regards Uwe
