Re: RAID down, dont know why!

Its something different than hardware, I am getting random failures now,
as in:

Normal (X marks no drive even present, U marks a drop):
A B X X
C D X X
E F X X
G H I X

First loss:

A B X X
C D X X
U U X X
U U I X

Second Loss:

First loss:

U U X X
C D X X
E U X X
G H U X

Just dropping randomly.

I had the system running under ubuntu 9.04 server for 1 month without
ever seeing this, it wont run an hour without this issue now. Currently
trying to find my 9.04 disk so I can just go back, I need this thing
online by wednesday.

I wish I could have easily gotten more information for everyone, this is
a huge problem for people with my setup. I think its possibly a
controller driver thing.

I just copied 4+ TiB of information to this array, restarted 5 times
and tried to access it.... What is going on?

It looks like you have 4 failed drives. sdl,sdi,sdj,sdk

Exactly.
Looks like one multilane cable is disconnected.
Each "feeds" 4 drives.

e f g h

Yes.  Tha is what I was thinking.  I asked Andrew to reseat cables,
and check to make sure that power is going to the block on the
backplane or mobile storage cannister.
