Hi
I had similar problems on our SMP machine, too - a while ago (2 Months
or so). I got
three U2W on the system, with two raid0 connect to the first ones and
the system disks
connected to the last one.
First days (as you) everything looks quit nice, but then I got timeouts;
I tried several
patches (kernel), mdutils and raidtools and so on.
At last I changed three disks (out of the raids) and one of the
controllers. Also the
cables and I decreased the length of the external cables (the raid disks
are in two
external arrays).
I don't know exactly (until today), but I think it is a problem
referring to the IBM
disks (I use them too) and the U2W. I never got an answer for the
problem for myself.
My only advice: proove your hardware; maybe the timeouts come only from
one of the disks
(in my case the same three disks gave timeouts).
Regards, Dietmar
