Hello,

I

Is there a way to print only volume group name on server with the highest number? for eg if the server has vg00, vg01, vg02 I want to have print only highest number vg which is vg02. I am trying to use with ansible\_lvm.vgs but couldnt able to. With shell command I am able to get the info but wondering if its possible with ansible\_lvm facts.

- debug:  
var: item  
with\_items:

- “{{ ansible\_lvm.vgs }}”

- shell: vgs --noheadings | grep -E “vg[0-9]” | sort | tail -n1 | awk ‘{print $1}’  
register: highest

- debug:  
var: highest.stdout

Output:

Try:

"{{ ansible\_lvm.lvs | select('match', '^vg[0-9]+') | list | sort | last }}"

var: highest\_vg

Thank you Dick Visser again for your help!
