I recently updated my keepalived cluster from version 1.2.10 to 1.2.13.
I noticed that my tracking script, which basicly just pings another system,doesn't work anymore. I use a simple bash script and return a 0 if everything is fine and the reciever is online, and 1 if the reciever isn't available.
If the Script returns a 1 the cluster changes and another router becomes active, otherwise everything is ok.
keepalived.conf:
global_defs
router_id r_id
vrrp_script chk_myscript
script "/etc/keepalived/chk_available.sh"
interval 4 # check every 4 seconds
fall 2 # require 2 failures for KO
vrrp_instance r_id

virtual_router_id 10

advert_int 1

auth_type PASS

ping_return()
ping -c2 8.8.8.8 > /dev/null #it's just an example ip
if [ $? -eq 0 ]
then
return 0
else
return 1
fi
ping_return
After the starting proccess of keepalived the log messages told me this:
VRRP sockpool: [ifindex(2), proto(112), unicast(0), fd(10,11)]
ROUTER keepalived_vrrp[2800]: Using LinkWatch kernel netlink reflector...
ROUTER keepalived_vrrp[2801]: VRRP_Instance(INSTANCE) NOW in FAULT state
I've already read the changelog because I thought I could get some helpful information. But there wasn't anything useful (at least for a total newbie like me).
My question now is:
Why doesn't keepalived work like in the former version and what do I have to do to let keepalive do it's work again?

Is this your real script? Because there's a bug, and it has nothing to do with the keepalived upgrade. You callping_return, but the function is calledping_test.

It's not a permission problem. The problem is "systemctl start keepalived". When I start keepalived via systemctl, keepalived enters into fault state and the process dies. When I start keepalived with "keepalived -D" it works perfectly. My tracking script sections works and everything is fine. I am presently trying to understand why systemctl got this problem.
