Hassbian boot problem

Archive HASSbian

Hi!

My hassbian won’t boot. I put the microSD card in my macbook and checked with the linux command mount and the boot partition is mounted as:
/dev/disk3s1 on /Volumes/boot (msdos, local, nodev, nosuid, noowners)

Checking under /dev I see the fiilowing special files:
ls -l /dev/disk3*
brw-r----- 1 root operator 1, 9 7 Sep 15:59 /dev/disk3
brw-r----- 1 root operator 1, 10 7 Sep 15:59 /dev/disk3s1
brw-r----- 1 root operator 1, 11 7 Sep 15:59 /dev/disk3s2

I cannot mount /dev/disk3s2:
sudo mount -t msdos /dev/disk3s2 .
mount_msdos: Unsupported sector size (0)

I havent been able to check /dev/disk3s2 either.

Do anyone know how many partitions there should be on the SD card, and how they are mounted?
If anyone can ssh to there hassbian, can you just do the mount command to see what is maunted and how?
Anyone who knows how to fsck these partitions?

The files on the boot partiotions below.

Best regars,
Rickie Kåveby

Now the boot partiion only contains these files:
cd /Volumes/boot/; ls -la
total 44103

but I think you are better off going to a backup or even downloading a fresh image, rather than trying to fix it.

Thanks a lot! Stupid of me, I don’t have a backup.

Hi again Gbenton!

From you answer I could see that /dev/mmcblk0p was mounted as a ext4 filesystem. Unfortunatelly Apple OSX can’t mount ext4 filesystems, however I downloaded ext4use for OSX and could mount the SD card readonly. So I have now backed up all relevant files. I’m going to find some machine that can mount the SD card ead write and see if I can find out something. It seems that the filesystem on the SD card is OK. COuld be filled up logs or something.

Thanks a lot for your print of mount!

If you can boot a live linux on your mac, it will mount ext4.
