Re: NCQ general question
Thank you Mr Garzik. Is there a list of all drivers and there features they give ? Raz.

Re: No syncing after crash. Is this a software raid bug?
Do you have write-cache enabled on the mirrors? How do I find out about that? Sometimes I have differences between RAID1 mirrors in 2.4, too. I have not experienced this with 2.4. However the 2.4 and 2.6 machines are not exactly the same hardware. But AFAIR they both use Promise controllers and Seagate disks. Even with clean shutdown or reboot sequences. Actually I think some of the differences on the swap device have happened on clean shutdowns. However, in my case, it turns out that this always affects areas which are free on the filesystem layer. Does the raid layer have any way to know if they are free and treat them differently? that I have md5sums of all my files which don't show up any differences when I either copy the non-zero content over the zeros or the other way around. OK. Then it may very well be free areas. (Or perhaps journal) Especially I have never experienced such normal differences on my swap RAID1 mirrors. So far I have only seen it happen on swap. I thought that might be because that machine swaps a lot.
