OS 12.2 - OSError: [Errno 30] Read-only file system

Installation Home Assistant OS
1

Getting this my logs after updating to OS 12.2 with one of my custom components. Anyone know what has changed to cause this ?

I have the same problem with Solarman integration. I tried downgrading back to OS 12.1 and it works again.

WARNING (SyncWorker_1) [custom_components.solarman.solarman] Querying [1028 - 1056] failed with exception [OSError: [Errno 30] Read-only file system]

The command to revert the update if anyone’s interested:

ha os update --version 12.1

See Release Notes – Known issues for 12.2.

But thanks for this thread – I found this note based on knowledge I need to downgrade…

There is a known issue in Supervisor making add-ons unable to use shared memory and create pseudo-terminals, manifesting with error messages usually mentioning Read-only file system. If you are affected, please wait for the next Supervisor release (2024.04.0) or downgrade to the previous OS version using ha os upgrade --version 12.1. This issue is fixed in Supervisor 2024.04.0 available in the beta channel.

This issue has been resolved with the latest release of Home Assistant Supervisor (2024.04.0). At least Home Assistant Core should exactly behave as before. :thinking:

@Holdestmade @ziizii @PetosS can you try ha core rebuild and see if this resolves the issue you are seeing?

To fix after update and issue seen in logs:

  1. ha core rebuild
  2. restart all rpi/box
  3. profit

Thanks @agners

Hey there. I am pretty new and coding is brand new to me. What exactly I´d need to do (and where) to get this running again, as I have the same issue. Running a OS 12.1 (tried to do an update on 12.2) - officially it´s not done, but getting same issues with plenty of times having READ-ONLY File system error logs… Can´t leveage Terminal within the sytem, as it´s also stating: couldn’t create directory /tmp/tmux-0 (Read-only file system)

Any hints (step by step) where and what to do?

Well, in particular as I am not able to add a ssh-key to my add-on → SSH & Terminal

I just installed the Terminal and SSH add-on, didn’t change any settings. Open the add-on UI and type the rebuild command above. My HA then restarted but you may have to manually reboot

Have you solved this problem for haos 12.2? I haven’t found any other threads anywhere. Updating core to 2024.4.4 does not solve the problem. The only thing that helps is rolling back the haos version to 12.1.
EDIT:
Okay, I didn’t read it. I understand that the “ha core rebuild” command helped

I have had an issue within my core data base, I reseted the full system to 12.1. (Core), without the data - and reinstalled the missing pieces. It worked. I also changed from SD Card to a SSD Harddrive to prevent issues like that in future.

had this issue after updating to HAOS 13.1 (hadn’t updated in a while) for a HA-native integration (Velbus).
ha core rebuild fixed it. Thanks !
