Unable to create bricks via webui - Ansible Folded Block Scalar with double quote issue - simple fix.

[puchalakd]

Unable to create bricks via webui.
In the logs I have found:
"Exception:[Errno 2] No such file or directory: b'echo /root/.local/bin:/root/bin:/usr/share/Modules/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin ; lvcreate -l 100%FREE --chunksize 256K --poolmetadatasize 16777.0 --zero n --type thin-pool --thinpool vmstore1_lv_pool RHGS_vg_vmstore1'"

/usr/share/ovirt-engine/ansible-runner-service-project/project/roles/gluster-brick-create/tasks/main.yml
contains 2 tasks that will never execute properly because of using double quotes with > (Folded Block Scalar).

Broken tasks are:

• name: Create a LV thinpool
• name: Create an xfs filesystem

Simple fix - remove double quotes for command in these tasks - they do not work with > (Folded Block Scalar).

Is:

- name: Create a LV thinpool
  ansible.builtin.command: >
    "lvcreate -l 100%FREE --chunksize {{ lv_chunksize }} --poolmetadatasize {{ pool_metadatasize }} --zero n
    --type thin-pool --thinpool {{ lvname }}_pool {{ vgname }}"

Should be:

- name: Create a LV thinpool
  ansible.builtin.command: >
    lvcreate -l 100%FREE --chunksize {{ lv_chunksize }} --poolmetadatasize {{ pool_metadatasize }} --zero n
    --type thin-pool --thinpool {{ lvname }}_pool {{ vgname }}

Is:

- name: Create an xfs filesystem
  ansible.builtin.command: >
    "mkfs.xfs -f -K -i size=512 -n size=8192 {% if 'raid' in disktype %} -d sw={{ diskcount }},su={{ stripesize }}k
    {% endif %} /dev/{{ vgname }}/{{ lvname }}"

Should be:

- name: Create an xfs filesystem
  ansible.builtin.command: >
   mkfs.xfs -f -K -i size=512 -n size=8192 {% if 'raid' in disktype %} -d sw={{ diskcount }},su={{ stripesize }}k
    {% endif %} /dev/{{ vgname }}/{{ lvname }}

Simple ansible playbook to reproduce the issue with double quotes and folded block scalar:

---
- name: Test
  hosts: localhost
  gather_facts: false
  connection: local

  tasks:
  - name: Folded Block Scalar test without double quotaion marks
    ansible.builtin.command: >
      id
      root

  - name: Folded Block Scalar test without double quotaion marks
    ansible.builtin.command: >
      "id
      root"
...
