I run my HomeAssistant on a RaspberryPi 4 from a SD card. Two days ago I did a upgrade to the newest version (I don’t remember if it was HomeAssistant or the Operating System) and since then it does not boot anymore.
I connected it via HDMI to a screen and got those errors:
It looks to me that the SD card is corrupted or something. Any idea if I can fix it in any way or do I need to redo the setup from scratch?
You must log in or # to comment.
Your image is itty-bitty here in Lemmy-land, at least, but a dead SD card on HA is… unsurprising.
It might be recoverable if you plug it into a linux box and try to extract the data, but as for recovering it, it’s the same as a dead hard drive: you might get data back, but the physical media is trash.
You probably want to NOT use a SD card and pick any other option (USB real SSD, NVMe hat, etc.) because, well, SD cards are not very good at this kind of use case. (HA writes a lot of historical data, and is basically always chattering away on the disk.)
I think you should be able to click on the image and make it bigger.
It’s not clickable but it might be because I’m not caching/proxying images on my install (single user install, so really, no reason to do so) and that causes some other unexpected interactions.
But yeah, that looks like a dead SD card; the failed to mount the partition and then ext4 complaining it’s in read-only mode is… probably not going to result in good things for your data :(
Ah, I didn’t make it a link to be clickable, sorry, fixed it now for everyone else ^^
Those EXT4-fs write access unavailable errors look spooky. Should probably do some standard Linux FS testing (fsck)
I’ve not had to recover anything from a raspberry pi SD card, but in the case you start from scratch - and considering it’s upset at write access - you may be able to plug it into another machine and at least salvage bits of its configuration that way.
Hope you were able to fix your Home Assistant. I just came to quickly recommend a way to easily backup your installation. https://github.com/sabeechen/hassio-google-drive-backup
2 things, one of which has already been said
Get an SSD and a usb cable for it. Boot off that. Be aware that not all cables are the same (have a Google for usb 3 SSD cables for home assistant before you buy one). There’s a little song and dance you have to do to boot off ext SSD but it’s not hard and doesn’t take long (Google).
That combo will eliminate the SD card issues in the future. But you also need to look into the Google Drive backup add-on. Get that for when shit goes down.
With those two things you should be all set and eliminate this ever happening again. If it does you have a backup.
