Hello,
I'm pretty new in ansible, so excuse me for this (stupid?) question, but it
bothers me.
I'm trying to set up LVM on the remote host with ansible.
Here is my role:
---
- name: install lvm2
yum:
name: "{{ item }}"
state: present
with_items:
- lvm2
tags:
- install
- name: select a drive for LVM
shell: "fdisk -l |grep vdb | awk '{print $2}'"
register: drive_for_lvm
tags:
- configure
- set_fact:
drive_for_lvm: "{{ drive_for_lvm.stdout_lines }}"
tags:
- configure
- set_fact:
drive_for_lvm: "{{ drive_for_lvm|replace(':','') }}"
tags:
- configure
############################## ADD LVM ###########################
- name: create VG
lvg:
vg: vg_test
pvs: "{{ drive_for_lvm }}"
pesize: 16
tags:
- configure
- name: create LV
lvol:
vg: vg_test
lv: lv_test
size: 100%FREE
pvs: "{{ drive_for_lvm }}"
tags:
- configure
When I execute it, I've got this:
root@ubuntu-latest:~/ansible# ansible-playbook -i group_vars/ playbook.yml
--skip-tags=install
PLAY [test]
********************************************************************************************************************************
TASK [lvm : select a drive for LVM]
********************************************************************************************************
changed: [docker2]
TASK [lvm : set_fact]
**********************************************************************************************************************
ok: [docker2]
TASK [lvm : set_fact]
**********************************************************************************************************************
ok: [docker2]
TASK [lvm : create VG]
*********************************************************************************************************************
changed: [docker2]
TASK [lvm : create LV]
*********************************************************************************************************************
fatal: [docker2]: FAILED! => {"changed": false, "err": " Physical Volume
\"[/dev/vdb]\" not found in Volume Group \"vg_test\".\n", "msg": "Creating
logical volume 'lv_test' failed", "rc": 5}
Then, I verified the host called "docker2" if it contains PVS /dev/vdb (and
it does).
[root@docker2 ~]# pvs |grep vdb
/dev/vdb vg_test lvm2 a-- 4.98g 4.98g
So why ansible says that there is no such physical volume?
I finally edited main.yml inside the role (just commented out pvs section
in last task):
- name: create VG
lvg:
vg: vg_test
pvs: "{{ drive_for_lvm }}"
pesize: 16
tags:
- configure
- name: create LV
lvol:
vg: vg_test
lv: lv_test
size: 100%FREE
# pvs: "{{ drive_for_lvm }}"
tags:
- configure
And it works as expected.. Can somebody explain the difference? It is a bug
or what?
Best regards!
