Ryan told me about this patch work and I have it tested in our system. It seems that it works, and the md raid rebuild speed is around 60MB/s for 16 hdd. However, the dd speed for when raid 5 is rebuiding is much less than original result. Around 150MB/s for write compared with almost 400MB/s without the patch. 600MB/s for read compared with 800MB/s. Is this caused by the bounce buffer for the alignment? Is there any way to solve this problem in lsi formware so that we don't need a forced alignment? We will test the software raid grow problem reported by Brian later. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.-- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
