Software TeddyCloud
1

Hi everyone,

I am also new to that and apologize for that question.
Does anyone understand what that following lines mean?

Hardware-Specs:
Fujitsu 6 x Intel(R) Core™ i5-8500T CPU @ 2.10GHz (1 Socket)
16GB RAM
Proxmox with docker (portainer) installed with the helperscripts to run teddycloud.

Everything worked fine. Then few months later power was interrupted without normal shut down of any container or proxmox itself.

Then teddycloud wasn´t reachable and docker was down.
I was able to restart docker and watched the logs in portainer.
I hope to have cleared all necessary private information in the following lines:

If you need further information, please let me know.

Any ideas? Thanks in advance.

There was an error which causes a crash. The error is described in detail in the log (try to double free some allocated memory). If I get it right somewhere around the image cache functionality. Do you have enabled cache images?

As you run the outdated teddycloud 0.6.2, I recommend to update teddycloud first.

If the error still happens with the latest version, then come back again.

Hi henryk,

thanks for the fast reply and answer.
Thanks 0xbadbee for moving to a new topic.

I tried to pull the update in the gui by image details → pull. Didn´t work. Deployment error “…no space left”.
Then i tried the solution to edit the stack and update stack → same error.
Sadly 1 container and network got lost by that.
Found out that the storage in proxmox wasn´t dynamic and my intelligence gave it only 4GB bootdisc-space :smiley:

Bootdisc made bigger in Proxmox.
Tried to edit the stack again and update stack - successfull.
Now I can reach TeddyCloud, my library, my toniebox and the tonies are there.
The update with pulling the image still didn´t work. But the workaround with editing the stack (found here) worked fine. Now everything is fine. That´s great.

Thanks again for your fantastic support and that impressive project.
