Hey All,

Trying to create a (when: ) condition, where a task runs only when a mount point does NOT exists.

- name: format disk with ext4  
filesystem: fstype=ext4 dev={{ item }}  
with\_items:
- /dev/xvdc  
when: ansible\_mounts.mount doesn’t contain “/path/to/my/mount/point”

The expectation is that ansible\_mounts contains 1 or more mount points.

Any ideas?

Thanks!

ansible\_mounts is a list of dictionaries, each of which has a 'mount'  
so you are really comparing to a complex structure, you can try  
something like this (though with set\_fact to create the list you  
need):

&nbsp;&nbsp;vars:  
&nbsp;&nbsp;&nbsp;&nbsp;newdevices:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- /dev/xvdc  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- /dev/sda1  
&nbsp;&nbsp;tasks:  
&nbsp;&nbsp;&nbsp;&nbsp;- debug: msg="mounted {{item.device}}"  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;with\_items: ansible\_mounts  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when: item.device in newdevices
