Let's > hope that helps. The load_cycle_counts are very high and that means your drive heads are parking all the time. Possibly multiple times a minute. I don't know if its your problem, but I'd say something is wrong and I've seen excessive head parking cause disk write failures in Windows. In linux I think it just wears out your drive way prematurely. And of course and i/o's are delayed if the heads are parked when the commands hit the drive. There is a linux package specifically targeting drives that have this issue. Hopefully it can at least keep your heads from parking continuously. storage-fixup. 1) Be sure you have the userspace package storage-fixup installed. 2) Look in /etc/storage-fixup.conf and see if your drives are in the list. If not, try to work with the storage-fixup maintainer (Tejun Heo?) to get your drives added. And while testing, watch Load_cycle_count and ensure it is not increasing too fast. ie. Several times an hour is fine. Several times per minute is too much.
