Hello, I have successfully installed and tested configuring software RAID1 as guided in http://www.howtoforge.com/how-to-se...-system-incl-grub2-configuration-ubuntu-10.04 on my test environment. However, my production server is with 2 TB drives, the partitions during installation created GPT. Now fdisk and sfdisk commands do not work with GPT which have been used in the said howto. I installed gdisk to deal with, and its almost similar to fdisk, but couldn't find alternative for sfdisk. Then I came to know about a comment by paul at http://www.howtoforge.com/how-to-se...ystem-incl-grub2-configuration-debian-squeeze. I am going to install it again as commented. I would like to invite suggestion and other ways of doing the same. Dipesh
