Bug with CLI pvesh

[itzxtoast]

Hello i have problems with the command "pvesh create /nodes/{node}/migrateall".
When i try from pve01: "pvesh create /nodes/pve03/migrateall -target pve01 -maxworkers 1 -vms 501" I can see the task and the migration in the webgui but in the cli i get following error:

"JSON text must be an object or array (but found number, string, true, false or null, use allow_nonref to allow this) at /usr/share/perl5/PVE/CLI/pvesh.pm line 125."

From pve03 the command works.

root@pve03:~# pvesh create /nodes/pve03/migrateall -target pve01 -maxworkers 1 -vms 501
Migrating VM 501
UPIDve03:00094DB8:0039A087:5C94873D:migrateall::root@pam:

I also tried the option --noproxy but get then the following error:

root@pve01:~# pvesh --noproxy create /nodes/pve03/migrateall --target pve01 --maxworkers 1 --vms 501
proxy loop detected - aborting

pvesh commands do not get proxied to other nodes, you could use the apiclient for this:
https://git.proxmox.com/?p=pve-apiclient.git;a=tree
or pve-client for external, which is at the moment in a "prototype" state:
https://git.proxmox.com/?p=pve-client.git;a=tree

pvesh is rather a debug utility, but yes, the error messages is pretty horrible...

Thanks for the quick reply. Is there any documentation how i can use one of the aboth tools?

 

[t.lamprecht]

For the apiclient there are examples:
https://git.proxmox.com/?p=pve-apic...ca5563abf4425887acb5821c99c59ca5b7e82;hb=HEAD

I mean it'd definitively help to have some basic programming concepts, but if you take the linked file, put it to a PVE node you can go to it's end and and just add lines there, e.g., in your case you could switch the get with a post:

$conn->post("api2/json/nodes/pve03/migrateall", { target => 'pve01', maxworkers => 1, vms => '512' });

(i did not directly tested this but I used the apiclient quite a few times and it should work)

This may seem a bit hacky, but the truth is that it's really powerful and once you get this you can automate alot of complex steps and get a deeper understanding of Proxmox VE's architecture.
Else you always got the Web GUI
