Hello!

I use zfs module for creating necessary structure.  
Using “with\_items” I iterate over elements in config list. It’s ok, but after all I need to unmount creating volumes.  
This must be done in reverse order for preventing “busy device”.

I need something like with\_items\_desc.

What can you advise?

This should do the trick I believe:

with\_tems: list|reverse

Look for ‘reverse’ on [http://jinja.pocoo.org/docs/templates/](http://jinja.pocoo.org/docs/templates/)

Hello,

The filter reverse returns a reverselistiterator and will be inappropriate here.  
I suggest you to use **with\_items:** your\_liste\*\*[::-1]\*\*

Newer versions of Ansible can iterate across iterators in that “with” and should not present a problem.
