But there might be an exception to that. That's no the case here though. They're all 80 pin, installed correctly - master drive connector on master drive, controller connector on controller end. The only possible part of your theory in my case may be problems with bending. I kept the cables fairly flat and straight, but they came tightly folded in the box. The more I think about it the more it seems like the system not keeping up with the drives though. Isn't it strange that both my 2000+ Athlons MP run at < 2% idle when syncing array? Even in PIO mode, at 500K resync speed reported by /proc/mdstat. And nothing else runs on the machine, Just three consoles, raidrun on one, top on the other and occasional tail /var/log/messages on third to monitor log for error msgs. When I let the drives supply data faster by enabling DMA (100 by default, but I've tried switching to 33 with same results), i start getting errors at 2000K resync speed. In slower PIO ar 500K resync things work ok with 4 drives, but 5 is too much - errors. Artur :.˛mkabzwmb˛mb)w* jg ݢjG j:+vwjm wfh٥
