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

Holdestmade · April 11, 2024, 3:54pm

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.

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

PetosS · April 12, 2024, 5:27am

This was fixed by ha core rebuild.
To fix after update and issue seen in logs:

ha core rebuild
restart all rpi/box
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
