Hi, I have 800+ machines all using Linux SW RAID-1. Recent kernels use modules for IDE (piix) and before those modules are loaded, I cannot turn on DMA. So I do this using hdparm from a rc.boot script. The problem is that usually fails with 'hdX: lost interrupt' if the disks are busy due to RAID reconstruction - which happens a lot as some of the 800+ machines get rebooted for various reasons... Of course I could be running without DMA (that's what I did on most critical machines), but that is painfully slow and it takes forever just to finish RAID reconstruction. So I need to know if there is any way (kernel parameter would be ideal) to delay reconstruction for X seconds/minutes? Any other suggestions to deal with the problem?
