ibm.power_aix.filesystem cannot be executed more than one time

[AIXruth]

I configured a NFS mount point via modul ibm.power_aix.filesystem. It works fine for the first time, but if I execute it a second time it will fail. The error occurs in the function compare_attrs(), because an expected array item does not exist (lines2[2])

To Reproduce
Use a similar task as and execute it more than one time. Afterwards you will get the error and traceback as below:

- name: Ensure NFS mount is defined in /etc/filesystems with dynamic NFS server
  ibm.power_aix.filesystem:
    filesystem: '/mksysb'
    nfs_server: '{{ nfs_server |trim }}'  # 
    state: present
    fs_type: nfs
    device: '{{ dev }}'
    permissions: 'rw'
    auto_mount: true

@schamola , Please make sure that this is fixed and get shipped with our next release.

[schamola]

Hi @AIXruth
Can you please provide the output of this command: lsfs -q /mksysb

[schamola]

@AIXruth
The issue seems to be arising because of the difference between outputs of lsfs -q command in case of JFS/JFS2 and other filesystems (like nfs).
We will push the fix soon!

[AIXruth]

Thank you for the correction. I can confirm from my side that multiple execution is now possible. However, I have noticed two other small errors:

• On the first run, the mount options are set to “bg, intr”. When executing again, the options are set to “rw,bg,hard,intr”.
• On further executions, /etc/filesystems is written to, although its content has not changed. With idempotent this should not actually be the case, right?

Both these errors are not relevant in MY case, but I wanted to mention them.

[schamola]

Thanks for confirming that It's working fine for you!

For some attributes, there is inconsistency in naming when using crfs and chfs commands... the issues that you have mentioned could be because of that.
That said, thanks for mentioning them, we will look into them and see if changes are required from our end.

[nitismis]

Closing this issue, we can have separate issue opened in case we need to change anything in the collection for 2 other errors mentioned.
