Moving to new system disk

Eli_pok — Fri, 16 Jan 2009 10:51:35 GMT

Hi,

I'm having mechanical problems with my sda disk which has 3 partitions :
/boot
the entire vg00
and swap.
I inserted a new disk (sdb) and partitioned it as the sda.
vg00 - was moved with pvmove.
swap - was moved with swapon/swapoff.

How do I move the /boot partition ?

p.s.
I'm using a RedHat 4.4 with LVM2.

Shalom,

You can use dd to copy the boot file system to the new disk. This will work and can be used to migrate or create a mirror copy of /boot

See the man page for syntax.

Before using dd all I need to do is fdisk and mark the partition as beatable ?

Is there any thing I'm forgetting ?

I meant bootble (automatic correction).

Shalom,

If you are going to a new disk device, you may need to update /boot/grub/grub.conf

Take a look at it before you try and boot.

You may need to use the grub utility to update the system configuration.

You'll need to install the grub boot block on the new disk to make it bootable. You should be able to do it with grub-install.
