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:
