Foreman Maintain

Here is an idea, when Satellite is in maintenance mode, create /sat-maintenance file or something. If that's present, cron jobs can be all skipped.

As per discussion with Lukas below we will try to implement,

1. We will check if Satellite is in maintenance mode ?
2. If its in maintenance mode we will exit all crons with exit code zero. Here we will make changes in below files,

1. this will be first line all cron jobs
   if -f /var/xxx && exit 0

/etc/cron.d/foreman
/etc/cron.daily/katello-repository-publish-check
/etc/cron.weekly/katello-clean-empty-puppet-environments
/etc/cron.weekly/katello-remove-orphans

My questions is, how we should know if Satellite is in maintenance mode ?

1. We are already creating a iptables chain 'FOREMAN_MAINTAIN' so should we just check if this chain exists, and if this is there then exit cron jobs ?
2. Should we create an maintain new file will will be in /var/lib/foreman-maintain/ directory which will help to know if Satellite is in maintenance mode ?

Thank You,

Isn't just stopping cron daemon sufficient? That could do it easily.

systemctl status crond

IMHO there must be a utility that allows you to enter, exit and test maintainance mode:

foreman-maintainance start

foreman-maintainance check
echo $?
1

foreman-maintainance stop

foreman-maintainance check
echo $?
0

Agreed, we've been tracking this in https://bugzilla.redhat.com/show_bug.cgi?id=1487559, I hope to get this one prioritized properly.

One more thing is, if user do not upgrade using foreman-maintain then should we check for 'satellite-installer' process in 'ps' and if its running then exit cronjob ? Because with forman-maintain we have pre scripts which will handle stopping crond service but if user just runs 'satellite-installer' then crond would be running ?

Lukas and Ivan,

I have one query regarding disabling cron jobs.
Currently, using iptables foreman-maintain set maintenance-mode on/off. so that, it blocks all incoming traffic towards the server.

Would it be good idea to include disable/enable cron-jobs under maintenance-mode itself?
