Hum, this is not what I'm looking for, because my action is not
executed on the ceph-OSDs, but on another host (a centralized admin
node).
In this playbook, I'm not doing anything on the ceph-OSDs.
What I need to do (only on my admin node) is :
- shell: echo {{ item.0 }}-{{ item.1 }}
with_nested:
- groups['ceph-OSDs']
- the disks of the current item in the "groups['ceph-OSDs']" loop
I want it to print (on the admin host) :
osd0-sdb
osd1-sdb
osd1-sdc
Do you understand the problem ? I don't see any workaround. This is a
matter of syntax.
