OSMC on Rasberry Pi Model b hangs on boot

[Nils]

Hi there,

actually I’m enjoying OSMC quite well since the first stable release. But today I ran into an problem:
The pi is always-on and after I turned on the TV today, it presented me nothing but a black screen. After a hard-reboot (unplug USB energy) the device seems to hang up at boot with the following lines:

Does anyone know what to do?
The only hardware, that is connected is a 720p-TV via HDMI, IR-receiver, and an USB stick (for USB-boot, which worked well the last weeks since installing OSMC).

New update error with base-files (8+deb8u2)

Pop your SD card into a PC - edit the file called cmdline.txt, at the end of the same line add a space then: fsck.repair=yes Save then try booting again. In theory this should force it to run automatically. If not please take another screenshot of the error you get.

[Nils]

Thanks for your answer ActionA!
Unfortunately the fsck.repair did not resolve the problem. My “cmdline.txt” looks like this now:

root=/dev/sda1 rootfstype=ext4 rootwait quiet osmcdev=rbp1 fsck.repair=yes

The system messages seem not change at all:

[ActionA]

Do you have another linux system handy that you can use to fsck the USB with?

[Nils]

After trying to fsck the USB with a Linux Mint VM (which didn’t work because VMware can’t pass non-mounted devices through to VM) I installed a Linux Mint partition on my Mac… Everything to end up in still not being able to mount the USB. I’ll attach regarding outputs:

dmesg “sees” the USB stick after plugging in:

This results in the typical “blob” sound for plugging devices in the USB port, but it’s not going to be mounted:

Sorry, no Linux genius here.

[ActionA]

You don’t want the partition mounted in order to fsck it. The fact that the partition is corrupted is probably why you can’t mount it.

[Nils]

fsck while a partition being mounted is not a good idea - that’s right at all. But AFAIK I have to mount the partition first, so I can use the old mount point (after unmounting) as parameter for fsck.

So my question is: How do I reference to the partition if it was never mounted?

fsck sdb1

…did not work.

[DBMandrake]

fsck /dev/sdb1

?

[Nils]

Well, that’s the same problem:

fsck von util-linux 2.20.1
e2fsck 1.42.9 (4-Feb-2014)
fsck.ext2: Datei oder Verzeichnis nicht gefunden beim Versuch, /dev/sdb1 zu öffnen
Ist das Gerät möglicherweise nicht vorhanden?

Sorry - German console. It’s the default “file or directory not found (…) Is the device maybe not present?” error message.

That’s why I thought the device has first to be mounted and unmounted.

[DBMandrake]

No, you do not need to mount a device before running fsck, it is enough that the block device (/dev/sdb1) exists. After booting up with the drive connected please provide the output of dmesg:

dmesg | paste-log

[sam_nazarko]

Also

sudo parted -s /dev/sdb print

May need to sudo apt-get install parted.

What concerns me is p1 > eod. That means the partition is expected to start further than the number of sectors that the disk has.

Sam

[Nils]

Okay - thanks for the explanation.
The “paste-log” command is not found on my machine. So I was just able to create an output after booting w/ connected device via “dmesg”. Because it’s a really long output, I uploaded it as txt on dropbox (didn’t want my post to explode, as I can see no spoiler-option in the forum-SW).
Dropbox - Error

Sam, many thanks go also to you for your effort!
parted was already installed on my machine - but your command results in an empty output (so just a new line waiting for the next command). I also tried “sudo parted -s /dev/sdb1”, which says, that the file or directory was not found.

[sam_nazarko]

paste-log is a command on OSMC systems. @DBMandrake was asking you to run it after booting the Pi with the drive connected.

Our official Pastebin is at http://paste.osmc.io. If you use paste-log on the Pi, you will get a paste.osmc.io URL automatically.

Sam

[Nils]

Oh okay - that was bad googling by me.

As my OSMC isn’t able to boot atm, I’m performing the Linuxcommands on my MacBook w/ Linux Mint installed on it… That’s why the OSMC specific command didn’t work

I transferred the txt to the official pastebin, so no one needs to click the Dropbox link.

Hi

Is Linux Mint running on the MacBook natively? Or under a virtual machine?

[ 5.100916] sdb: sdb1
[ 5.100920] sdb: p1 start 4096 is beyond EOD, enabling native capacity
[ 5.106001] sdb: sdb1
[ 5.106005] sdb: p1 start 4096 is beyond EOD, truncated
[ 5.110419] sd 6:0:0:0: [sdb] Attached SCSI removable disk

Does not look good. If parted is not giving you output, it may not be detecting a partition table. Try fdisk /dev/sdb as a last shot. Othewise, the USB seems to have corrupted.

Sam

[Nils]

Okay… I made a mistake yesterday - I’m sorry (it was late…). I forgot the “print”-parameter for “parted -s”.

I corrected that: “sudo parted -s /dev/sdb print” gives following output:

Error: Can't have a partition outside the disk!

I also used fdisk. It goes to interactive mode if I use “sudo fdisk /dev/sdb”. So to get an output for you I tried “sudo fdisk -l /dev/sdb”. Here’s the output:

Disk /dev/sdb: 2 MB, 2097152 bytes
186 heads, 19 sectors/track, 1 cylinders, total 4096 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00049ab8

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1            4096     7819263     3907584   83  Linux

Hope that helps.
Nils

edit: Linux Mint runs natively on the MacBook.

[sam_nazarko]

The partition table is broken. You will probably not have much luck here. We can try and reconstruct the partition layout, but I can’t guarantee the end of the partition.

*** No support. Use at own risk ***

Download my partition layout I have created for you here:

http://collaborate.osmc.tv/index.php/s/IxNPIxWnvWjOHsZ.

Run the following command:

sudo dd if=playout.img of=/dev/sdb bs=512 count=1

Hi Sam,
unfortunately this didn’t work. I copied the image on my USB stick successfully, but it’s still not working. I’m going to set up OSMC new for now. I hope the problem doesn’t appear again.
