Xbian not starting: Can't access tty

[harmenzon]

Hi all,

After installing an using Xbian 1.0 beta successfully for a while, it suddenly stopped within the init process.

Code:

mount: mounting /dev/mcblk0p2 on /rootfs failed: No space left on device
Mounting root partition dev/mcblk0p2 failed

/bin/sh: can't access tty; job control turned off

Any suggestions how to solve this?

Can you reference here first. http://forum.xbian.org/announcements.php?aid=8

As a **wild** guess, I'd say your SD card is full.

1) What size SD card are you using?
2) What add-ons have you installed?
3) Have you copied *anything* onto the SD card?
4) Was it a *fresh* install or an upgrade?

From there, we *might* be able to assist.

16Gb

Download package

Quote:3) Have you copied *anything* onto the SD card?

No, but probably downloaded.

Quote:4) Was it a *fresh* install or an upgrade?

fresh install

I agree with you, I think the SD card is full. But how do I get access to for example:

Code:

/home/xbian/incomplete

or more likely

Code:

/media/usb/incomplete

or more likely

Code:

/media/usb/incomplete

1) Try <cntl> <alt> <del> from the screen and see if that puts you in a login screen.
2) Use the SD card in another machine and edit the cmdline.txt file and add avoid_safe_mode=1 (This should put you in safe mode).
Try in the RPi
3) Rename cmdline.txt to cmdline.txt.bak
Try in the RPi
Hopefully, one of the above, will get you to a terminal screen.

Also see https://github.com/xbianonpi/xbian-package-initramfs/wiki/XBian-specific-cmdline.txt-options and the "rescue" options.

Unfortunately, all the above failed. I will start a fresh install again.
Too bad that I have to configure all the download packages again...

I have the same issue.

/dev/mmcblk0p2 30G 414M 30G 2% /run/media/rbellamy/xbian-root-btrfs
/dev/mmcblk0p1 34M 20M 15M 59% /run/media/rbellamy/8B12-9112

Clearly my SD card isn't full.

@harmenzon - did you by chance do a kernel upgrade before the boot failure? or were you using the the experimental "partswap" switch in cmdline.txt?

try to mount readonly first, then umount and mount with rw again.

(you can do it from the shell you are dropping into after the error. just to "mount -o ro /dev/mmcblk0p2 /rootfs", "umount /rootfs", "mount -o rw …"

if you succeed with ro option, check dmesg | tail for any messages relevant to btrfs. in nothing, you can always put "debug" into cmdline.txt to force lot of debugging info.

hi all!

I had the same problem: starting xbian, it stopped at init process....

Well, after read your post, I decided to do somethig: start xbian but first unplug the hard disk... Solved, xbian start fine again.

@kas_27_es

is the mentioned disk listed in /etc/fstab ? if so, can you try adding "nobootwait" parameter to mount options and try again ?

can you put "rescue" into cmdline.txt and in the shell you will be dropped to do:

Code:

mount -o subvol=/ /dev/mmcblk0p2 /tmp
btrfs sub list /tmp

if you see

Code:

root/@safe
home/@safe

you can remove them with

Code:

btrfs sub delete /tmp/root/@safe
btrfs sub delete /tmp/home/@safe

can you post "btrfs fi df /tmp" - in case you are still in the shell. if you can boot 'normally' then it's "btrfs fi df /" .
