OK, thanks for the details on the setup. Did you try with max_sector_kb values between 512 and 32767? I wonder if we can find a happy middle ground, like 1280 or even 2048. I'll try to setup a software raid 5 with 10 disks and get back to you. If you have a preference for the exact geometry, please speak up. Thanks!
