I am using HAOS for a few month on a Raspberry Pi4
Unfortunately after some problems with the power supply the SD card has some Problems. The Pi won’t start. I was able to recover the /homeassistant folder.
Is this sufficient ?
What are the correct steps to bring ist back to life ?
If you are using windows you can get apps which allow you to read linux ext drives in explorer. Like this one. I have not tried it so can’t comment on whether it works or not. You will then be able to view the backup folder on your SD card.
When you have it working setup something like google drive backup to save a lot of this hassle.
I have reactivated an old linux notebook and when trying to mount the data volume I got a Bad Superblock error.
After fsck /dev/sdb8 I was able to mount the data volume. I copied all .tar files from /supervisor/backup. Hopefully this backup set is able to restart the Homeassistant.
After connecting the Pi to a display it shows that booting is no problem the system ended in the ha cli.
Where could I go from this point the HA is still not available.
After a lot of experimenting, I gave up and used RaspberryImager to create a new SD card.
It looks like the partial backup was sufficient to recover from backup.
fsck /dev/sdb7 does the trick to be able to recover the /supervisor/backup folder.
