[SOLVED] Not able to retrieve disk' aio information via API

[maco1717]

Hi,

When trying to get the aio (Asyn IO) information from disk on VMs I cannot reach this information via API. I have tried pvesh and API (using tokens).


My environment is the following version

According to the API documentation I was hoping to be able to access the "Return object" for disk information in the format column


When using pvesh I get the following pvesh get /nodes/[NODE]/qemu/[VMID]/config


Using the API accessing Tokens to the same location I am getting

data:null

I cannot event get a list of VMs /api2/json/nodes/[NODE]/qemu (obviously queries via API, I do get a list of VMs via pvesh)

data:[]

I was hopping to get more information via API rather than less. I am wondering is the reason for this is because I am using Token based authentication.

Perhaps the version of PVE doesn't return this information.

Any advise would be appreciated.

if it's the default value, it won't show up in the config. Try setting it to e.g. "threads".

If you can't get a list of VMs, you're probably missing permissions

Oh wow. That was a quick reply. I changed the Token "permission" to NOT Privilege separation. That returned the list of VMs via API query.

When I changed the Async IO to non default it started showing via API query.

All good.
Thanks.

Great! Please mark the thread as solved (edit it, there's a dropdown near the title) so others with the same problem can find it more easily.

How did you change the Token permission? I've using pvesh to query the machines configs, but I feel like I'm fumbling around in the dark.
