I'm looking for a howto guide that will allow me to convert my currently running system (FC6) from a non RAID system to a RAID-1 (mirror) system using IDE driver (hda and hdc) without loosing the existing data on the system. Current partition table is: Filesystem 1K-blocks Used Available Use% Mounted on /dev/hda6 2972236 280372 2538448 10% / /dev/hda1 505604 14881 464619 4% /boot tmpfs 1037684 0 1037684 0% /dev/shm /dev/hda7 58449748 10858968 44573776 20% /home /dev/hda2 5944440 2073532 3564068 37% /usr /dev/hda5 3765832 337868 3233580 10% /var swap is on /dev/hda3 TIA Jeff
