Hi Groups,

I am using ansible.builtin.mountd module to mount and add the entry in the fstab in couple of hosts but I see that its adding \040 for the white space . How to get rid of this junk character being added to /etc/fstab?

192.50.250.2:\040/POOL1\040 /POOL1 nfs nfsvers=3,soft,bg,timeo=12\0400\0400 0 0

My code is
vars:
mount_point:

  • path: “/P1”
    nfs_server: “192.50.250.2:”
    source: “/P1”
    fstype: nfs
    opts: “nfsvers=3,soft,bg,timeo=12 0 0”
  • path: “/Test-Data”
    nfs_server: “192.62.150.231:”
    source: “/volume9/Test-Data”
    fstype: nfs
    opts: “nfsvers=3,rw,bg,rsize=131072,wsize=131072,soft,proto=tcp,sec=sys 0 0”

nfs_mount_hosts:

  • “dev-app601”

  • “dev-sgapp601”

  • “tst-sgapp601”

  • “tst-app601”

  • name: Mount NFS directories P1
    become: true
    remote_user: testops
    ansible.posix.mount:
    fstype: “{{ mount_point[0].fstype }}”
    src: "{{ mount_point[0].nfs_server }} {{ mount_point[0].source }} "
    path: “{{ mount_point[0].path}}”
    opts: “{{ mount_point[0].opts }}”
    state: mounted
    delegate_to: “{{ item }}”
    loop: “{{ nfs_mount_hosts }}”

I appreciate your help.

Thanks

Note that “\040” is octal. The hex equivalent is 0x20 or decimal 32, a.k.a. and ascii space.

If the octal expression is being expressed in your /etc/fstab rather than the literal space character, that sound like a bug. Which versions of Ansible and ansible.posix are you using?

Hi,

please take a look at your task:

- name: Mount NFS directories P1
   become: true
   remote_user: testops
   ansible.posix.mount:
     fstype: "{{ mount_point[0].fstype }}"
     src: "{{ mount_point[0].nfs_server }} {{ mount_point[0].source
}} "

you are *explicitly* asking for `src` to have a space in the middle and
one at the end. Since spaces are used as separators in /etc/fstab, the
module correctly quotes your `src` value with space being replaced by
\040.

The same is true for \040 in the options, that comes from the value you
provide, which contains spaces:

    opts: "nfsvers=3,soft,bg,timeo=12 0 0"

Cheers,
Felix

Hi Felix ,

Thank you for the input. By combining the src and nfs servers to src variable I am able to get rid of one space but I have a variable path where I have this problem. not sure how to handle variable path? and for the opts i did get rid of fsck check which will default is zero

source: “192.50.250.2:/P1”

opts: “nfsvers=3,soft,bg,timeo=12”

10.50.226.248:/POOL1**\040** /POOL1 nfs nfsvers=3,soft,bg,timeo=12 0 0

I am just looking to get rid of the \040 on the path variable.

Thanks,
Deepak Kumar
