I am using software RAID 1 under Linux on a bootable partition. I am worried that when a disk dies or is corrupted, the system might boot from the empty replacement disk or from that corrupted disk (instead of the good one) and start overwriting the good disk with no or bad data. Is this a valid concern? If so, does anyone have a good strategy for preventing it?
into raid one you don't access the drives directly but trough a second layer so you should not be worry FYI http://www.howtoforge.com/software-raid1-grub-boot-debian-etch describes as well the way to install grub which is the boot loader.
