This isn't tested. I ran it successfully for a single known added disk of
/dev/vdb. But take a look and it might help:
- name: "finding recent added device"
shell: bash -c 'comm -23 <(lsblk -l | grep disk | cut -f1 -d" ") <(lsblk
-l | grep part | cut -c1-3 | uniq)'
register: fdisk
- debug:
msg: "New disks are {{fdisk.stdout_lines}}"
- name: partition check
parted:
device: "/dev/{{item}}"
unit: GiB
register: "{{ item }}"_info
with_items:
- "{{fdisk.stdout_lines}}"
- name: partition drive
parted:
device: "/dev/{{item}}"
number: 1
label: gpt
part_start: 0%
part_end: 100%
name: "{{ item }}"-pv
state: present
with_items:
- "{{fdisk.stdout_lines}}"
when: {{item}}_info.disk.table == "unknown"
- name: make-volg
lvg:
vg: "{{vg_name}}"
pvs: "/dev/{{item}}1"
pesize: 32
with_items:
- "{{fdisk.stdout_lines}}"
