Let's hope so, anyway. Our prayers have not been answered :-( I tried several things: - Forcing all the 500GB Seagate drives to 3.0Gbps does not help - Replacing the 500GB drives with 1.5TB drives seems to make the PCI error much less frequent - Moving the controllers to different slots (on different busses) does not help - Happens with both 2.6.26 (from lenny) and 2.6.30 (from sid) - Unplugging one of the controllers appeared to lead to a stable configuration, but yesterday I left the machines reconstructing the arrays and this mornings one of them is not answering to pings ;-( I want to try reducing the frequency of the PCI-X bus, but the BIOS doe= s not seem to provide a setting for it. Is there another way? --=20 // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/
