ibm.power_aix.mount mounts remote NFS successfully, but doesn´t umount it.

[StevePOI]

Describe the bug

I use ibm.power_aix.mount as roles in my playbooks, one task to mount a certain NFS (for EMGR, INSTALLP Module etc...):

---

• name: Mount NFS '{{ NFSMOUNT }}'
  ibm.power_aix.mount:
  node: '{{ NFSMOUNT }}'
  mount_over_dir: /mnt
  mount_dir: /swdepot

And afterwards I umount it again:

---

• name: Umount NFS '{{ NFSMOUNT }}'
  ibm.power_aix.mount:
  state: umount
  mount_over_dir: /mnt

Today I noticed that the umount part is not working anymore, it gives this "OK" message, so everything is green:

ok | msg: Filesystem/Mount point '/mnt' is not mounted

(Line https://github.com/IBM/ansible-power-aix/blob/dev-collection/plugins/modules/mount.py#L433 )

This behaviour must be relatively recent, it used to work in the last months of 2023 and I´m using this since 2021.

So I´m left with many mounted /mnt on my systems after each job run, please advise :) .

To Reproduce

Use the ibm.power_aix.mount Module to umount a remote NFS v3.

Expected behavior

According to https://github.com/IBM/ansible-power-aix/blob/dev-collection/plugins/modules/mount.py#L456 it should be:

result['msg'] = "Unmount successful."

And /mnt should be gone.

Environment (please complete the following information):

• OS: [e.g. AIX 7.2.4.0] AIX 7.2.5.7
• Python Version: [e.g. 2.7.5, 3.6] 3.9.18
• OpenSSH Version: [e.g. 1.0.2] 9.2.112.2000 (using 3.0.10.1002 openssl)
• Ansible Version: [e.g. 2.10.7] ansible [core 2.14.13]
• AIX Collection Version: [e.g. 1.2.1] 1.8.1

Addendum:

It works on a machine where the NFS is permanently mounted and in the /etc/filesystems:

Umount NFS 'nfs-swdepot'...
NIMSERVER_NAME done | msg: Unmount successful.

After running the playbook /mnt is gone here, while the other servers who only mount it via Ansible temporarily report:

aix72test01t ok | msg: Filesystem/Mount point '/mnt' is not mounted

while it is still there:

[aix72test01t:/home/USER]# mount|grep /mnt
nfs-swdepot /swdepot /mnt nfs3 Feb 29 12:38

I´m confused, is this a check further up in the code?

[StevePOI]

Addendum, this works as expected, so it seems it´s nothing specific about my AIX servers but a change in the ibm.power_aix.mount Module:

---

• name: Unmount NFS '{{ NFSMOUNT }}'
  ansible.posix.mount:
  path: /mnt
  state: unmounted

Hello @nitismis !

Can I provide any additional information :) ?

Thanks,

With kind regards,

Steve

@StevePOI ... I will prioritize this defect in our next sprint (starting Monday). You can provide the verbose out of the playbook.

Thanks

@nitismis

Thanks for including it in the next sprint!

Is this verbose enough (-vvvv, we always see those kerberos messages):
