Description

Ohai,

when I try to restore a Katello 4.3 (or nightly) on EL8 (with rubygem-foreman_maintain-1.0.2-1.el8.noarch), the restore finishes fine, but afterwards not all services are happy:

After restarting dynflow via systemctl restart dynflow-sidekiq@\* everything seems to work fine again.

I am not sure this is a maintain bug (or installer, or dynflow, or packaging), but filing it here for investigation.

Looking at the logs, it seems dynflow was disconnected from the database and didn't manage to reconnect:

Okay, I can reproduce this without Foreman Maintain and without the Installer on a fresh Katello nightly (and also on 4.2). Just turn off the DB for 60 seconds (a restart is not always sufficient):

The Katello part is only really needed as Katello exports the status of dynflow/tasks in the Ping API, which Foreman itself does not.

more fun:
  • systemctl stop postgresql; sleep 30; systemctl start postgresql; sleep 10; hammer ping; sleep 10; hammer ping - first ping thinks it's OK, second FAILED
  • systemctl stop postgresql; sleep 20; systemctl start postgresql; sleep 10; hammer ping; sleep 10; hammer ping - those two OK, but later flips to FAILED
  • systemctl stop postgresql; sleep 10; systemctl start postgresql; sleep 10; hammer ping; sleep 10; hammer ping - all OK, and later ones are also OK

something is trying hard to survive, but fails at some point

<aupadhye> Zhenech, I dont think anything is pending to close https://projects.theforeman.org/issues/34394 ?
<Zhenech> it depends how you look at it
<Zhenech> if you say the redmin is for the workaround, then yes
<Zhenech> if you say it's a bug in dynflow (it is) then no
<aupadhye> then.. i keep it open
