Description mailinglists 2016-05-15 12:41:55 UTC

When doing "systemctl stop keepalived" there's a high probability that keepalived does not stop. This may relate to using vrrp_script.

Version-Release number of selected component (if applicable):
keepalived-1.2.19-2

How reproducible:
80-100%

Steps to Reproduce:
1. systemctl start keepalived
2. systemctl stop keepalived
3. Notice it's still running

Actual results:
Running keepalived

Expected results:
Stopped keepalived

Comment 2 Ryan O'Hara 2016-05-23 14:46:29 UTC

Appears the be the same bug as reported in Fedora (BZ#1280437). I believe this issue was fixed by specifying PIDfile in the systemd unit file, but it is important to note that I was not able to reproduce the problem. I had a script that did start/stop of keepalived, then checked to see if keepalived was still running and never ran into this bug.

Comment 6 Strahinja Kustudic 2016-10-11 12:30:52 UTC

The problem is with running "systemctl restart keepalived", because after restart systemd keeps the old main PID, so stop doesn't work. I reported that bug to keepalived as well https://github.com/acassen/keepalived/issues/443.

The solution is to add:

PIDFile=/var/run/keepalived.pid

That way systemd will be able to detect the main PID of the process after restart.
