Mirroring root volume group

I am an HPUX administrator and new to RHEL 5. I want to mirror my root. Except /boot, I am using LVM for other filesystems like /, /var, swap, /opt, /tmp, /usr and /home. I want to mirror /boot (which is not on LVM) as well as other file systems.

Can some one please provide me instructions for that.

Thanks in advance.

Re: Mirroring root volume group

1) if you need to mirror the entire disk, clonezilla will do the job. Download ISO from the website and make bootable CD.

2) if you need only a single partition, boot from a Linux CD to rescue mode, and use 'dd if=/dev/sda1 of=/dev/sdb1 bs=512'. Partitions have to be identical in size.
