Salt: How Salt-Master End a Salt-job ?

[Colstuwjx]

Hi, I did some job by salt, and found something maybe confusing:

# I set the salt-master use a domain name
master: domainname

and salt-minion connect salt-master ok when it's up.
But if there is someone changed the DNS settings in /etc/resolve.conf, and make salt-master's domain name cannot be resolved, it will make all pub job be running forever.

Just like:

#master
salt '*' cmd.run 'w'

#minion
run w and cannot return

How salt-master cancel a salt-job? If there is some forever-running dead job, salt-master will still send "saltutil.find_job" and waste time to wait???

thks.

@Colstuwjx, thanks for reporting this.

You can find running jobs with salt <minion> saltutil.running. From that output you can kill the job with salt <minion> saltutil.kill_job <jid>, see http://docs.saltstack.com/en/latest/topics/jobs/index.html.

My point is that when minion's DNS changed, all salt-master pubed jobs will still be running at minion side as it cannot resolve the Salt-master's DNS.
