LinuxQuestions.org - How to copy OS disk of 76 GB to 146GB and make it bootable

Hi, I want to copy OS disk 76 GB (linux Red-Hat enterprise Version 5-1 )
to a 146 GB disk and make it bootable on a Proliant 380 G5.
Both disk are configured as raid 0 and are located in slot 1 and slot 2.

First I create the partition on the second disk and I used dumpt and restore to clone the OS. See all the steps.

The problem is I cannot boot after clooning the disk.

I get the following error:

Atempting Boot From Hard Drive (c:)
GRUB

It seem it do not copy the MBR. How can I make the disk bootable ?

Any Suggestion ?

Thanks !!!

See the following Steps:

I have 2 disk. OS disk with one blank disk

[root@ecsccsrv5 ~]# fdisk -l

Disk /dev/cciss/c0d0: 73.3 GB, 73372631040 bytes
255 heads, 63 sectors/track, 8920 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/cciss/c0d0p5 1161 8920 62332168+ 83 Linux

Disk /dev/cciss/c0d1: 146.7 GB, 146778685440 bytes
255 heads, 32 sectors/track, 35132 cylinders
Units = cylinders of 8160 * 512 = 4177920 bytes

I created the partition on the new disk as follow:

[root@ecsccsrv5 ~]# fdisk -l /dev/cciss/c0d1

Disk /dev/cciss/c0d1: 146.7 GB, 146778685440 bytes
255 heads, 32 sectors/track, 35132 cylinders
Units = cylinders of 8160 * 512 = 4177920 bytes

Device Boot Start End Blocks Id System
/dev/cciss/c0d1p1 1 25 101984 83 Linux

/dev/cciss/c0d1p4 2182 35132 134440080 83 Linux

3) Now I create the files system:

mkfs.ext3 /dev/cciss/c0d1p1
mkfs.ext3 /dev/cciss/c0d1p3
mkfs.ext3 /dev/cciss/c0d1p4

Now I will mount the new file system:

root@ecsccsrv5 ~]# mount /dev/cciss/c0d1p1 /mnt_boot
[root@ecsccsrv5 ~]# mount /dev/cciss/c0d1p3 /mnt_var
[root@ecsccsrv5 ~]# mount /dev/cciss/c0d1p4 /mnt_roo

[root@ecsccsrv5 ~]# df -t ext3

/dev/cciss/c0d0p5 60378404 2980060 54281736 6% /

/dev/cciss/c0d1p4 132330024 192132 125415888 1% /mnt_root

Now I will copy the filesystem from Os disk to new disk as follow:

see the result after the copy:

According to me all data are copy to the new disk except the MBR

How can I copy the master boot record without overlapping the disk partition.

Let me know what is wrong.

The previus Steps work fine on unix and should work with linux
