Unable to edit file using lineinfile Ansible module - file

Question

I'm trying to add a line export TMOUT=50000 to a file /backup/backup.sh using Ansible.
Below is my playbook:
- name: Add Timeout Entry if not present
lineinfile:
path: "/backup/backup.sh"
insertbefore: BOF
state: present
line: 'export TMOUT=50000'
Getting the below error for ansible playbook:
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: OSError: [Errno 18] Cannot link to a file on another device.: b'/tmp/tmphtvszlfc' -> b'/wd/backup.sh'
fatal: [10.9.16.133]: FAILED! => {"changed": false, "msg": "The destination directory (/wd) is not writable by the current user. Error was: [Errno 13] The file access permissions do not allow the specified action.: b'/wd/.ansible_tmp3yhi8j7bbackup.sh'"}
Below is the drive information of the target server:

The file is definately editable:
/wd>ls -ltr /wd/backup.sh
-rwxr-xr-x 1 user1 dba 173 Apr 05 17:15 /wd/backup.sh
/wd>ls -lad /wd
drwxr-xr-x 1 root system 173 Apr 05 17:15 /wd/backup.sh
Kindly suggest how can I overcome the issue?

Answer 1

The error message is explicit: the user cannot write into the directory of the file, /wd; you can even see that in your ls output: drwxr-xr-x 1 root system says the directory is w-ritable only by root
The fix is very simple: add become: yes to your task, to enable privilege escalation when running that lineinfile task:
- name: Add Timeout Entry if not present
become: yes
lineinfile:
path: "/backup/backup.sh"
insertbefore: BOF
state: present
line: 'export TMOUT=50000'
