Moving to new system disk

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.

Re: Moving to new system disk

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

Is there any thing I'm forgetting ?

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.

Re: Moving to new system disk

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.
