Hi guys, I followed the link http://wiki.centos.org/HowTos/SoftwareRAIDonCentOS5 and configured RAID 1 with my Seagate 500 GB X 2 Hard disks everything is fine.
I also tested it by disconnecting one hard disk at a time and it boots from the next hard disk and vice versa. When both the hard disks are connected I booted my system from HDD 1. and saved a file in my home and desktop. But when I disconnected my HDD 1 and booted my system from HDD 2. But the file which i have saved was not in my home folder. When I disconnected my HDD 2 and booted my system from HDD1. The file was there in my home. This shows me that the actual purpose of RAID1 (Mirroring) was not happened there. Please guide me.
