[CLOSED] qmp command 'balloon' failed - Invalid parameter type for 'value', expected: integer

[mircsicz]

Hi all,

I'm running an installation on which I get the above message in the syslog every 30 Secs.

As I don't find any additional info google'ing the message I hope one of you has a hint...

The error you're seeing occurs during auto-ballooning... Not sure why though.

Could you start pvestatd in debug mode and post your output?

# pvestatd stop
# pvestatd start --debug
... wait a few minutes, you should see logs appearing ...
... then, kill pvestatd (might need to do this from another terminal/session via 'pkill pvestatd' ...
# pvestatd start

Hi Stefan,

thx for the help. Attached you'll find the requested log's:

Waited for three minutes... But even after 6-8 Minutes there were no additional entrys ;-)

Thanks for the logs. Multiple people have now also reported the issue over here: https://forum.proxmox.com/threads/host-instable-after-update-5-0-21-5.60404/

Taking the conversation there.

 

[mircsicz]

I saw that thread before I started that Thread...

I'll join the conversation over in the other thread

BTW: For anybody finding this further down the road, here's the Bug-Report @Stefan_R created...
