Perhaps I was asking a stupid question or an obvious one, but I have received not response. Maybe if I simplify the question... If I am running software raid1 and a disk device starts throwing I/O errors, Is the filesystem supposed to see any indication of this? I thought software raid would mask all of this and just fail the drive. I have servers with xfs as the filesystem and xfs will start to throw I/O errors when a disk starts acting up even with software raid in between. Please advise on how I can confirm my setup or if this is possibly a bug how to diagnose further. If it makes a difference, I am running linux-2.4.26 Thanks --David Dougall - 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
