The patch Keld sent me makes a significant difference: Before: (Stock 2.6.25.11 x86-64 openSUSE 11.0 kernel raid10 module): 4.5h to 5.5h After: Same kernel, minor changes to raid10.c and compiled: 1h 56m. :: Aug 4 18:37:09 turnip kernel: md: data-check of RAID array md0 Aug 4 20:33:24 turnip kernel: md: md0: data-check done. > My idea is to do the checks in bigger blocks, then you would minimize > the trashing, by minimizing the number of times you need to move the > head. And this would not need much change in the code. I have done a > patch to do this, but I have not yet tested it. -- Jon -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
