Hi,

I have fresh set up a software raid-1 with 2 SATA disks successfully on my
new Mandriva 2008.1 (spring). This is my first instalation MDV 2008.1.
Everything seemed to work well until I tried to imitate a disk failure. I
turned the box off and unplugged one (any of two disk in mirror) HDD. After
I did that it was impossible to reboot because system didn't mount . If I
unplugged third disk (/dev/sdc) was the same situation. Now I have plugged
both drives again and everything works again. Why did this failure test not
work?
