na_ontap_volume: fails to delete volume when state is set to absent

[raffs]

na_ontap_volume faisl to delete a volume on a filer when using state: absent

i created a new 1GB test volume using the ontap CLI , to test the deletion process. ... like so ....

emdccn0006::> vol create -vserver emdccn0005v55dr -volume testvol_12345 -aggregate emdccn0006c02_aggr2 -size 1g -state online

emdccn0006::>
emdccn0006::> vol show testvol_12345
Vserver Volume Aggregate State Type Size Available Used%
--------- ------------ ------------ ---------- ---- ---------- ---------- -----
emdccn0005v55dr testvol_12345 emdccn0006c02_aggr2 online RW 1GB 972.6MB 5%

emdccn0006::>
emdccn0006::>

emdccn0006::> version
NetApp Release 9.1P16: Wed Nov 14 19:51:52 UTC 2018

emdccn0006::>

so filer = version 9.1P16 

the ansible doco for na_ontap_volume shows the following example ...

- name: Volume Delete
  na_ontap_volume:
    state: absent
    name: ansibleVolume12
    aggregate_name: ansible_aggr
    vserver: ansibleVServer
    hostname: "{{ netapp_hostname }}"
    username: "{{ netapp_username }}"
    password: "{{ netapp_password }}"

so following on from this .....

i then created a yml file to delete the volume using ansible like so ...

$ cat delete-dr-volume.yml
---

- hosts: localhost
gather_facts: false

name: "Ansible Storage Delete ..."
tasks:

- name: "Delete Volume : testvol_12345 , if it exists ..."
na_ontap_volume:
state: absent
name: testvol_12345
aggregate_name: emdccn0006c02_aggr2
vserver: emdccn0005v55dr
hostname: emdccn0006.dc.corp.abc.com
username: admin

the specific error is : 

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: KeyError: 'No element by given name volume-comp-aggr-attributes.'

Can anyone assist me with my issue ? Not sure what i'm doing wrong, unless the fix is a netapp-lib upgrade ?

Hi Adrian,

The slack channels on https://netapp.io  is the quickest place to get help on this.  

A few points about what's going on. 

1.  You might want to consider a ONTAP upgrade to 9.5+ 

2.  I don't think you need to specify the aggregate_name in the remove command

3. You might need to unmount the volume prior to deleting it.

4. ONTAP collections have replaced the syntax your currently using which would also address points 2 and 3 above there is a blog post on netapp.io that addresses this topic. 

I hope this helps!

Fixed by putting 

collections:
    - netapp.ontap

in playbook. 

As mentioned in https://netapp.io/2019/09/17/coming-together-nicely/

---
- hosts: localhost
  collections:    - netapp.ontap
Don't forget to do the action above this section.

I'm facing the same issue with error "No element by given name volume-comp-aggr-attributes." when running a playbook with na_ontap_volume: onto ONTAP Release 9.1P9

This happens when run the playbook for the 2nd or more time.

Is this due to the lower ONTAP-release?

Hello @maartendeboer ,

Yes, it is due to running ONTAP 9.1P9 as composite aggregate also referred to as FabricPool wasn't introduced until ONTAP 9.2.
