First check with the head-to-head restart is confirming my former assumption on Zesty it is: 1. not failing 2. taking longer each restart
I wanted to go further but a trivial test comparing with this: $ time for i in $(seq 1 200); do sudo systemctl restart keepalived; sudo systemctl status keepalived | egrep 'Main.*exited'; done Failed for the default start limit kicking in. Well, lets start softer and go with reload first. $ time for i in $(seq 1 200); do sudo systemctl reload keepalived; sudo systemctl status keepalived | egrep 'Main.*exited'; done That works fine on both (but also the HUP just forces a reload and the PIDs stay). So this by-design does not fall into the same fault. Ok, so with that lets obey the default start-limit of 5 starts per 10 seconds and compare again. Xenial: $ time for i in $(seq 1 5); do sudo systemctl restart keepalived; sudo systemctl status keepalived | egrep 'Main.*exited'; done Main PID: 8800 (code=exited, status=0/SUCCESS) Main PID: 8836 (code=exited, status=0/SUCCESS) real 0m0.156s user 0m0.008s sys 0m0.000s Note: 2 cases is all we can get, restart #1 works, #2 is too early triggering the issue, #3 cleans up, #4 triggering again, #5 cleaning up again. Zesty: $ time for i in $(seq 1 5); do sudo systemctl restart keepalived; sudo systemctl status keepalived | egrep 'Main.*exited'; done real 0m2,258s user 0m0,012s sys 0m0,000s So that seems to be the repro we need: - head to head restarts with no time in between - showing the error on Xenial - showing it is not occuring on Zesty - showing something on Zesty makes it "wait" which is what avoids the issue -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1644530 Title: keepalived fails to restart cleanly due to the wrong systemd settings To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/keepalived/+bug/1644530/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
