pvesh error

[elurex]

I keep getting pvesh error complaining json malformat
/usr/share/perl5/PVE/CLI/pvesh.pm @ line 125

sub proxy_handler {
    my ($node, $remip, $path, $cmd, $param) = @_;

    my $args = [];
    foreach my $key (keys %$param) {
        next if $key eq 'quiet' || $key eq 'output-format'; # just to  be sure
        push @$args, "--$key", $param->{$key};
    }

    my $remcmd = ['ssh', '-o', 'BatchMode=yes', "root\@$remip",
                  'pvesh', '--noproxy', $cmd, $path,
                  '--output-format', 'json'];

    if (scalar(@$args)) {
        my $cmdargs = [String::ShellQuote::shell_quote(@$args)];
        push @$remcmd, @$cmdargs;
    }

    my $json = '';
    PVE::Tools::run_command($remcmd, errmsg => "proxy handler failed",
                            outfunc => sub { $json .= shift });

    return decode_json($json);
}

my command send to PVE API is

pvesh set /nodes/pve1/qemu/810/config --scsi0 "rbd:vm-810-disk-1,cache=writeback,discard=on,iops_rd=8000,iops_wr=8000,mbps_rd=400,mbps_wr=400,size=60G" --scsi1 "rbd:vm-810-disk-2,cache=writeback,discard=on,iops_rd=8000,iops_wr=8000,mbps_rd=400,mbps_wr=400,size=200G --hostpci0 "04:00,pcie=1,x-vga=1" --net0 "virtio=7A:83:E0:CB:92:58,bridge=vmbr0"

can you try to execute that command on the 'pve1' node and post the complete output ?

 

[elurex]

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

then you did not execute it on node 'pve1' since it still tries to proxy it
please execute it on the node where you want the information from and post the output

Hi,

I have the same problem. I want to run this command to create an snapshot of the VM ID=157:

sudo pvesh create /nodes/pmx-smb-3/qemu/157/snapshot -snapname test123

If I run this command in the node `pmx-smb-3`, I have this output:

UPID:pmx-smb-3:000722EE:03B1FA8E:5E2787AA:qmsnapshot:157:root@pam:

* the exit code of the command is 0,
* and the snapshot is well created.

Now, if I execute exactly the same command in `pmx-smb-1`, I have this output:

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.

* the exit code of the command is 255,
* and the snapshot is well created (despite the non null exit code).

Here is some info about my cluster (all nodes are identical) :

Thx for your help.
