Hello list,
I am a newbie playing with heartbeat / pacemaker on ubuntu 12.04 LTS. I
have defined the following resource primitives and switchover/fail-over
works almost fine.
primitive ip1 ocf:heartbeat:IPaddr2 \
params ip="10.10.10.2" nic="eth0:0"
local_start_script="/home/user1/ipadded"
primitive ip1arp ocf:heartbeat:SendArp \
params ip="10.10.10.2" nic="eth0:0"
The firewall/router in the datacenter does not accept gratuitous ARP
(according to the manual: to prevent ip-spoofing). However, as a
work-around, I have a script that forces the router to reset the arp
table for the virtual ip. How can I tell the crm to run this script when
the IPaddr2 resource is moved?
I found a parameter "local_start_script" that can be passed to
ocf:IPaddr2, but the IPaddr2 script ignores this parameter. In a post to
this list, a patch to IPaddr2 was proposed, but not accepted.
primitive ip1 ocf:heartbeat:IPaddr2 \
params ip="10.10.10.2" nic="eth0:0" \
local_start_script="/home/geodan/ipadded"
There also exists the ocf:anything script, but this script expects a
parameter 'binfile' that should point to a deamon, not a one shot script.
So, is there a simple - best practice - way to run a one-shot script on
switchover / fail-over / fail-back?
Thanks,
Anne Blankert
