Running multiple Salt States at a time on same Minion

[Abul Barakath]

Hi Experts,

 

When we run Salt States using “salt-call state.sls <state name>” for multiple states at a time we are getting errors like below and it is failing. So, running multiple states at a time not supported? We are with Salt master & minion version of 2014.1.7.  

 

We have actually scheduled running “state.sls” via scheduler and it is sometimes quite difficult to control the timing. Is there a way that we can work around this issue?

 

“The function "state.sls" is running as PID 5348 and was started at 2014, Aug 07 06:42:49.868240 with jid 20140807064249868240”

 

Thank you.

 

Regards,

Abul

The state system is not architected with parallel execution in mind.  Much like a package management system, the complexity would be too high.  So we have a state lock in place which makes it so that multiple state runs cannot be run at the same time.

I think what you're looking for is the `queue` argument [1].  Note that queued state runs don't timeout, so if a state run gets stuck, it will just wait forever.  Open issue to fix is here [2].

In 2014.7 you can run state.sls with concurrent=True, but it's dangerous unless you know your states won't conflict with each other when you're running them concurrently.

concurrent=True appears to be completely broken for Windows minions, according to my testing.

If all you want is to run multiple states, but not necessarily in parallel, just provide a comma separated list of states to run. As documented here.

@Benjamen,

Did you file a issue on the SaltStack github repo? If so, can you point me to it? I couldn't find one when I searched.
