1  Linux Stuff / General Linux questions / Re: Busybox tar: "corrupted octal value in tar header" rootfs.tar.gz on: November 24, 2009, 01:32:47 AM
Hi rooster,

I'll try and I'll let you know.

I'll install ubuntu on SD card then tar the content of SD card without /proc and /sys folder and install on NAND.

Thank you very much for tip.

Hi rooster,

I done few tests, the first was to reduce size of rootfs.tar.gz but I was not a solution... (from 223 to 196)
I found a solution, but honestly I don't know what was the problem, maybe you can help me to understand.

before to copy rootfs on usbkey I stopped these services:

/etc/init.d/apache2 stop
/etc/init.d/cron stop
/etc/init.d/firebird2.0-super stop [my custom package]
/etc/init.d/networking stop
/etc/init.d/ssh stop
/etc/init.d/udev stop

an then it worked, I think that probably the problem is /dev folder could be ?

Here my solution for to make a custom Sheevaplug :

# Sheevaplug
1. Install what you need...
2. Stop all services that you don't need, in my case are:
# /etc/init.d/apache2 stop
# /etc/init.d/cron stop
# /etc/init.d/firebird2.0-super stop
# /etc/init.d/networking stop
# /etc/init.d/ssh stop
# /etc/init.d/udev stop
#
3. mount USBKEY ext3 formatted in a favorite place, e.g. /usb
# mount /dev/sda1 /usb
#
4. Change dir and copy the rootfs
# cd /
# cp -ax / /usb
# cp -a /dev /usb
#
5. Umount your USBKEY
# umount /usb
#
6. Remove the USBKEY from SheevaPlug and plug it on your Linux box
7. Change to the USBKEY dir in my case /media/SHEEVA_USB
# cd /media/SHEEVA_USB
#
8. Tar your rootfs
# sudo tar -zcf /tmp/rootfs.tar.gz *
#
9. Copy new image on usb installer folder and run installer 1.0


thank you very much for your answer rooster!

3  Linux Stuff / General Linux questions / Busybox tar: "corrupted octal value in tar header" rootfs.tar.gz on: November 23, 2009, 02:19:14 AM
Hi to all,

first of all a want to tell thank you for great SheevaPlug and installer!
I have a problem when I try to install my custom rootfs.tar.gz using installer way, I get an error
when installer procedure try to decompress my rootfs.tar.gz, the error is <tar: "corrupted octal value in tar header">

So here the steps that I done:

1. update my sheeva with installer 1.0 and its original rootfs.tar.gz
2. install my package apache2, php etc... change root password and hostname.
3. recreate my custom rootfs.tar.gz in this way:
#
# From SheevaPlug
#
# Insert my usbkey on it (formatted as ext3)
# Create a folder usb (mkdir /usb)
# Mount it in a folder that I created (mount /dev/sda1 /usb)
# Copy all rootfs file inside usb folder (cp -ax / /usb)
# Copy Dev folder (cp - a /dev /usb)
# Unmount usbkey (umount /usb)
#
# From my ubuntu 9.0.4 box
#
# Mount usbkey (it is automounted from ubuntu in a folder /media/USB)
# change dir to usbkey (cd /media/USB)
# Tar my rootfs (sudo tar -zcf /tmp/rootfs.tar.gz *)
# the resulted image is an rootfs.tar.gz about 223.9 MB (234802572 bytes)
#
4. Prepare an USBKEY for installer 1.0
5. Format it as fat32
6. Copy the files inside it
# My custom rootfs.tar.gz
# initrd (original file of installer 1.0)
# modules.tar.gz (original file of installer 1.0)
# uImage (original file of installer 1.0)
7. Move to installer folder
8. Run sudo php ./runme.php nand

When installer try to decompress my custom rootfs.tar.gz it return the error <tar: "corrupted octal value in tar header">
Maybe are there some option that I have to add when I Tar my rootfs ?

I also tried to install busybox on my ubuntu, and try to compress my rootfs.tar.gz using busybox tar: (sudo busybox tar -czf /tmp/rootfs.tar.gz *)
but it always return <tar: short write>

Some infos:
Linux ubuntu uname -a:
# Linux BLRBOOK 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009 i686 GNU/Linux
Tar command version

Could somebody help me to resolve this problem please ?
I googled about  "corrupted octal value in tar header" and seam that busybox must be compiled with this flag
CONFIG_FEATURE_TAR_OLDGNU_COMPATIBILITY=y

If so, could installer Team provide a path ?

Thank you very much for any help and still a great compliment to all people that support SheevaPlug project!

Andrea
