Hi I am new to Ansible and writing my first playbook

I want to update /etc/fstab

UUID=f2550ab4-36cb-4ff0-8afa-9e7839f7ce9f / ext4 defaults 1 1
UUID=988c830a-6d78-49f9-9db3-e8617f6dd8d0 /boot ext4 defaults 1 2

UUID=7b3871c8-1e46-4e3d-94fb-946c2a559c54 /data5 ext4 defaults 1 2
UUID=d5024ed8-34f3-470a-98a6-17d909c8ef84 /data6 ext4 defaults 1 2
UUID=8419d6e7-cc79-4692-954a-37ba50664f3b /srv ext4 defaults 1 2
UUID=9f80f114-1e6a-4ba3-aeb7-b72073600a97 /var ext4 defaults 1 2

with

UUID=f2550ab4-36cb-4ff0-8afa-9e7839f7ce9f / ext4 defaults,noatime 1 1
UUID=988c830a-6d78-49f9-9db3-e8617f6dd8d0 /boot ext4 defaults,noatime 1 2
UUID=4a60645a-9009-483a-9d3e-572a9fe355b8 /data1 ext4 defaults,noatime 1 2
UUID=2e7eef98-defb-4c6a-8262-799be5ddc9dd /data2 ext4 defaults,noatime 1 2
UUID=e19069ba-0ecf-4e54-8316-8ef2cc9e6758 /data3 ext4 defaults,noatime 1 2

UUID=8419d6e7-cc79-4692-954a-37ba50664f3b /srv ext4 defaults,noatime 1 2
UUID=9f80f114-1e6a-4ba3-aeb7-b72073600a97 /var ext4 defaults,noatime 1 2

I was following http://docs.ansible.com/replace_module.html

so I tried

tasks:

  • name: this is my task
    #lineinfile: dest=/etc/fstab regexp=defaults line=“defaults,noatime” state=present backup=yes
    replace: dest=/etc/fstab regexp=‘(\s+)defaults 1 2(\s+.*)?$’ replace=‘\1defaults,noatime 1 2\1’ backup=yes

which did following

UUID=b203e2c3-5207-41a8-8f18-795b5ec6550f / ext4 defaults 1 1
UUID=d966c414-907d-4a76-86ac-ea74922769d3 /boot ext4 defaults,noatime 1 2
UUID=92f6aef9-7701-4278-b5b3-161b595bb017 /data2 ext4 defaults,noatime 1 2
UUID=4943436a-0cef-45b2-a0df-a0c236b90697 /data4 ext4 defaults,noatime 1 2
UUID=db5435e6-e8f0-4646-9937-bea39e5d3470 /var ext4 defaults,noatime 1 2

what wrong am I doing here ?
thanks

You should use mount module for this http://docs.ansible.com/mount_module.html

replace: dest=/etc/fstab regexp=‘(\s+)defaults 1 2(\s+.*)?$’ replace=‘\1defaults,noatime 1 2\1’ backup=yes

does not match

UUID=b203e2c3-5207-41a8-8f18-795b5ec6550f / ext4 defaults 1 1

because of ‘1 1’ vs ‘1 2’

Cheers,
