Hi! I’m from germany and my raid and me needs help.
My english isn’t very good, but i think it’s sufficient. And i think, this mailinglist is my last hope ☺
So on, …. Here ist my problem.
The raid5 has lost 2 of 5 disks. First one disk and then the second one.
I have been trying for several weeks to solve the problem alone … unsucessful ☹
And here some informations about this disaster.
