Proxmox API - Edit Disk io_limit issues

[Vengance]

Hi,

I'm trying to edit the io read and write limit for an existing vm disk via the api.
However the request fails with the response ""scsi0": "'import-from' requires special syntax - use <storage ID>:0,import-from=<source>".

I'm not quite sure how to properly format the request and which values are needed.

// Set resources
        $response1 = Http::withToken($apikey)->asForm()->post('https://' . $server->hostname . ':8006/api2/json/nodes/' . $server->node . '/qemu/' . $vmid . '/config', [
            'cores' => $cores,
            'cpulimit' => $cpuLimit,
            'memory' => $memory,
            'net0' => "model=virtio,rate=" . $portLimit,
            'scsi0' => "import-from=local-zfs:base-" . $templateid . "-disk-0,file=local-zfs:base-" . $templateid . "-disk-0,mbps_rd=" . $ioLimit . ",mbps_wr=" . $ioLimit,
        ]);

Hi,
if the disk already exists you shouldn't use import-from (that would create a new disk and copy over the contents of the other disk), but just set scsi0 to <storage>:<disk>,mbps_rd=<val>,... where <storage>:<disk> is the currently attached disk (which you can GET from the current configuration).

Works like a charm, thank you!

Hmm, irgendwie tauchen bei mir auch weiterhin eine zusätzliche Unused Disk 0 auf.
Hier der API call

'scsi0' => "local-zfs:base-" . $templateid . "-disk-0,mbps_rd=" . $ioLimit . ",mbps_wr=" . $ioLimit,

Resultat:

Ich denke das Problem ist, dass Du nicht die selbe Disk i.e. local-zfs:base-9000-disk-0/vm-disk-0 zuweist, sondern die Disk der Template-VM i.e. local-zfs:base-9000-disk-0.

Wie gesagt, am besten einen GET-Call auf die Config machen, den Wert von scsi0 parsen und die gewünschten Optionen anhängen/ersetzen.
