I bought a ZimaBlade 7700 in March 2025 and love it!
I am a beginner but learning as I go. I have built a great Jellyfin server and add Tailscale to access it.
Last week I started adding Portainer and Jellystat with no problems.
(see list of containers)
- portainer-ce
- jellystat
- postgres
- tailscale
- watchtower
- jellyfin
- flaresolverr
- freshrss
- ttydbridge
- audiobookshelf
Then as I was building a python project I noticed some changes. The internal space was getting full.
with this command “sudo du -ah --exclude=/mnt/Storage1 / | sort -hr | head -n 50” it showed
9.4G /var
6.7G /DATA
6.3G /var/lib
5.5G /var/lib/docker
5.3G /var/lib/docker/overlay
2 5.1G /DATA/AppData
5.0G /DATA/AppData/jellyfin/config
5.0G /DATA/AppData/jellyfin
4.9G /DATA/AppData/jellyfin/config/data
4.7G /DATA/AppData/jellyfin/config/data/metadata
4.0G /DATA/AppData/jellyfin/config/data/metadata/library
3.3G /usr
3.0G /var/log
2.6G /var/log/journal/0f507a5baa8049f782c918f47c84387d
2.6G /var/log/journal
1.4G /usr/lib
1.4G /snap
1015M /snap/dotnet-sdk/256
1015M /snap/dotnet-sdk
I started cleaning old docker images and decreasing logs and got to about 6-7% free space (better then 1 GB free out of 27GB)
One reason that I even noticed that space was getting full was that portainer wasn’t loading a local environment. I would click on local (which said it was UP), then it would say “local environment not found” and go to DOWN status.
I tried to: Go to Portainer web UI → Home → Add environment, choose Docker Standalone → Local, then connect to /var/run/docker.sock
Nothing worked.
CasaOS UI would also have a popup at the top saying “loading apps” over and over.
I upgraded debian which also might have caused a lot of issues:
Commandline: apt-get upgrade Requested-By: casaos (1000) Upgrade: containerd.io:amd64 (1.7.29-1~debian.11~bullseye, 2.1.5-1~debian.11~bullseye), docker-ce-cli:amd64 (5:28.5.2-1~debian.11~bullseye, 5:29.0.0-1~debian.11~bullseye), docker-ce:amd64 (5:28.5.2-1~debian.11~bullseye, 5:29.0.0-1~debian.11~bullseye), docker-ce-rootless-extras:amd64 (5:28.5.2-1~debian.11~bullseye, 5:29.0.0-1~debian.11~bullseye) End-Date: 2025-11-11 00:33:43
I restarted docker, portainer, casaos, and still having CasaOS error and docker not finding Local.
I updated docker but got this:
casaos@casaos:~$ sudo docker run --rm -v /var/run/docker.sock:/var/run/docker.sock docker:24.0.5-cli ps
…
Status: Downloaded newer image for docker:24.0.5-cli
Error response from daemon: client version 1.43 is too old. Minimum supported API version is 1.44, please upgrade your client to a newer version
My client and server docker version was Version: 29.0.0 API version: 1.52 (minimum version 1.44)
I also tried adding “export DOCKER_API_VERSION=1.52” to /home/casaos/.bashrc but that might not have helped the situation
One other issue was that at the top of the CasaOS UI it said there was a new HDD. I only have one and didn’t touch anything, so not sure why the system thought there was another new one. Maybe when an update or reboot it thinks there is a new ‘duplicate’ one when /mnt/Storage1 is working just fine already. Maybe a bug since sudo journalctl -u casaos.service | grep “found new drive” didn’t have anything new.
My MAIN issue is that I restarted CasaOS via UI and then got:
Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key
Finally found out how to change it to boot again but now CasaOS doesn’t have ANY apps. it says it can’t find containers, env, or apps. It’s like a fresh install but at least the HHD is still linked (but no way to get to it really unless SSH to device).
I’m afraid my old CasaOS is gone and I have to do a fresh install of CasaOS. I know the files are still somewhere but not sure WHERE. Main items I want to save are project files in /home/casaos and any metadata in Jellyfin. The video files are in the HDD but if I can recover the Jellyfin metadata that would be awesome. Do I have to use SCP to recover all this because I can’t get any apps running in fear anything new will just be pointless if I can restore easily. I want to restore to an earlier state but I don’t think that’s possible.
Sorry for the mess of variety of topics but wanted to cover all that I’ve done to see if any of it is related to each other.
I can try to give logs or specific commands if needed.
