CentOS - Dec 2005 - Ghost 8.0 Clone Filesystem with ext3 (remove resize_inode and ext_attr features)

Try using Acronis True Image or G4U (Ghost 4 Unix), I have had really 
good luck with both.  Imaged both CentOS only or dual boot machines 
without out error.  Norton/Symantec doesn't seem to care about 
Linux/Unix systems anymore, so I have switched for all of my back/image 
needs.

This give a "dirty" solucion for remove special thing of ext3 (Selinux
remove resize_inode and ext_attr features) witch cause the error in ghost.

I hope somebody help with the problem of norton ghost and clone centos 4.

Solution to using Ghost 8 with Core 3 and 4
Good news : It can be done

Bad News : You have to turn off SELinux Forever and remove resize_inode 
and ext_attr features
from filesystem. Also if you mess this up it could kill your system, so 
I would use G4U (Ghost 4 Unix) to image it first before you try.

Here's the procedure to remove resize_inode and ext_attr features
from filesystems on an FC3 or FC4 installation. Everything must be done 
from
the root account.

Step 1

If you installed FC3 or FC4 with SELinux enabled, which is the default, it
you must disabled. Log on the system and edit /etc/selinux/config.
Replace SELINUX=enforced by SELINUX=disabled. If you don't disable
SELinux, the ext_attr will be set again on the root filesystem the
next time you boot and every file created or modified will have its
extended ACL entries set.

Step 2

Download e2fsprogs-1.36-rc5 from SourceForge. Click on the following
link:

http://sourceforge.net/projects/e2fsprogs

Step 3

Untar, compile and install the new utilities:

tar -zxf e2fsprogs-1.36-rc5.tar.gz
cd e2fsprogs-1.36-rc5
./configure
make
make install

Step 4

Reboot the system in single-user mode:

type reboot

at the GRUB splash screen, press enter then press the 'a' and
add the word single at the end of the command line (there's a space
between quiet and single)

Step 5

Unmount all filesystems, including /, and remove both resize_inode
and ext_attr features. Run the following commands on all filesystems:

debugfs -w /dev/XXXX -R "features ^resize_inode ^ext_attr"
e2fsck -y -f /dev/XXXX

Example:

/dev/sda1 is mounted on /boot
/dev/sda2 is mounted on /
/dev/sda5 is mounted on /home

umount /boot
umount /
umount /home

debugfs -w /dev/sda1 -R "features ^resize_inode ^ext_attr"
debugfs -w /dev/sda2 -R "features ^resize_inode ^ext_attr"
debugfs -w /dev/sda5 -R "features ^resize_inode ^ext_attr"

e2fsck -y -f /dev/sda1
e2fsck -y -f /dev/sda2
e2fsck -y -f /dev/sda5

Running e2fsck on the root filesystem takes a while.

Step 6

Reboot the system.

During shutdown, you will get error messages telling you that the
root filesystem cannot be written. That's normal because the root
filesystem is still mounted read-only. It must remain mounted read-
only during shutdown.

During boot, you will get a message telling you that the system was
not properly shutdown and ask you if you want to verify the
filesystem integrity. You can skip this step. It didn't find anything
wrong on my system.

Your system is now ready to be Ghosted.
