Simultaneous chef run handling on linux/windows

Chef Infra (archive)
1

Here I am, back with more windows questions…

We have just started to run chef in daemon mode. Previously we had only
been running it on demand.

Our deployment scripts trigger chef runs, and can be fired off at any time.

On Linux, if the chef-client daemon is running, you get a warning message:
[2013-08-16T14:28:27-04:00] WARN: Chef client is running, will wait for it
to finish and then run.

And things go along happily from there.

On Windows, you get:
[2013-08-16T14:23:44-04:00] FATAL: Errno::EACCES: Permission denied -
C:/chef/cache/chef-client-running.pid

Is there a setting in client.rb / something I can do to prevent these
errors on Windows?

Thanks for reporting this one as well Brian…

http://tickets.opscode.com/browse/CHEF-4470

My suspicion is that here (https://github.com/opscode/chef/blob/master/lib/chef/run_lock.rb#L61) FD_CLOEXEC is creating some issues on windows.

You can work around this by setting splay to 0 and instead of running “chef-client” during deployment you can run “net stop chef-client && net start chef-client”.

Thanks,
Serdar

I'm glad to see that it was reproducible!

I'll have to add some additional handling in our scripts to do the
stop/start of the client when the target is windows.
