Hello,
root problem in a 4.3.8 environment is that sometimes when I hot add a
floating disk to a VM in web admin gui, it attaches and also activates it
by default (the flag is checked by default, but you can uncheck it) and
this two-phases action fails as a single step.
What I get is:
VDSM ovhost command HotPlugDiskVDS failed: Requested operation is not
valid: Domain already contains a disk with that address
And then the VM event regarding hot add disk failure.
I'm going to investigate more: it should be a past bug already solved in
theory by my libvirt sw version (I've to crosscheck its id)... but I still
get the error sometimes.
What programmatically works is to attach the disk without activating it
(this step always completes with success) and then activate the disk as a
separate operation (this one typically fails the first time when I have the
"problematic" situation, but then the second time succeeds).
So I would like to use it as a workaround in the mean time.
The problem reflects using the ansible module ovirt_disk, that by default
activates the disk. So I have tried to specify "activate: no" (introduced
in 2.8, readings the docs) when I attach it, but it seems not to work as
expected.
I'm testing using awx and its info says:
AWX 9.0.1.0
Ansible 2.8.5
I tried this on a VM that (as usual when you want to reproduce... ;-)
doesn't show the problem:
ovirt_disk:
auth: "{{ ovirt_auth }}"
state: attached
activate: no
name: "{{ tobe_sw_disk_name }}"
vm_name: "{{ ansible_hostname }}"
size: "{{ current_sw_disk_size }}"
interface: virtio_scsi
delegate_to: localhost
register: disk_attach_info
But going to see registered variable it contains "active: true":
"disk_activate_info": {
"changed": false,
"id": "6f7cdf02-cf8b-4fa8-ac00-6b47f6e0c827",
"diskattachment": {
"href":
"/ovirt-engine/api/vms/b5c67c93-bd5d-42b6-a873-05f69cece2f1/diskattachments/6f7cdf02-cf8b-4fa8-ac00-6b47f6e0c827",
"id": "6f7cdf02-cf8b-4fa8-ac00-6b47f6e0c827",
"active": true,
"bootable": false,
"disk": {
....
In fact I followed with the step to activate the disk:
ovirt_disk:
auth: "{{ ovirt_auth }}"
state: present
activate: yes
name: "{{ tobe_sw_disk_name }}"
vm_name: "{{ ansible_hostname }}"
size: "{{ current_sw_disk_size }}"
interface: virtio_scsi
delegate_to: localhost
register: disk_activate_info
But in playbook run I got:
ok: [target_vm -> localhost]
And inside registered variable "changed: false":
"disk_activate_info": {
"changed": false,
"id": "6f7cdf02-cf8b-4fa8-ac00-6b47f6e0c827",
"diskattachment": {
"href":
"/ovirt-engine/api/vms/b5c67c93-bd5d-42b6-a873-05f69cece2f1/diskattachments/6f7cdf02-cf8b-4fa8-ac00-6b47f6e0c827",
"id": "6f7cdf02-cf8b-4fa8-ac00-6b47f6e0c827",
"active": true,
...
Any tip to realize what needed: task to only attach disk without activating
it and then task to activate the disk?
Thanks in advance,
Gianluca
