Neil hello Sorry for the delay. too many things to do. I have implemented all said in : http://www.spinics.net/lists/raid/msg11838.html As always I have some questions: 1. mergeable_bvec I did not understand first i must admit. now i do not see how it differs from the one of raid0. so i actually copied it and renamed it. 2. statistics. i have added md statistics since the code does not reach the statics in make_request. it returns from make_request before that. 3. i have added the new retry list called toread_aligned to raid5_conf_t . hope this is correct. 4. your instructions are to add a failed bio to sh, but it does not say to handle it directly. i have tried it and something is missing here. raid5d handle stripes only if conf->handle_list is not empty. i added handle_stripe and and release_stripe of my own. this way i managed to get from the completion routine: "R5: read error corrected!! " message . ( i have tested by failing a ram disk ). 5. I am going to test the non common path heavily before submitting you the patch ( on real disks and use several file systems and several chunk sizes). It is quite a big patch so I need to know which kernel do you want me to use ? i am using poor 2.6.15.
