We have 2 server one is old server like 4 year old other one is just brought both the hardware is similar, on the old server we using centos 4.5 last 1900days old server is not rebooted.
Now we want to make clone without reboot old server (oldserver = serverone)all production data is there on serverone with that we wanted to clone.
We had work around like as follow:-
SERVERONE as root
tar cfl /boot /tmp/boot.tar tar cfl /(root) /tmp/root.tar tar cfl /data /tmp/data.tar
SERVERTWO as rescue mode using 1st cd of centos
fdisk -l /dev/sda
creating new partition
/dev/sda1 * /boot 300MB (same as serverone) /dev/sda2 <swap> 2G /dev/sda3 / fdisk -l /dev/sdb
creating new paration
/dev/sdb1 /data mkfs.ext3 /dev/sda1 mkfs.ext3 /dev/sda3 mksf.ext3 /dev/sdb1 mkswap /dev/sdb2
cd /dev/sda1 scp root@serverone:/tmp/boot.tar . cd /dev/sda3 scp root@serverone:/tmp/root.tar . cd /dev/sdb1 scp root@serverone:/tmp/data.tar . cd /dev/sda1 tar xf boot.tar cd /dev/sda3 tar xf root.tar cd /dev/sdb1 tar xf data.tar chroot /mnt/root grub-install
please help me if you any suggestion for above work around or any tools which make .iso of live and we can use on servertwo.
