Clonezilla Buffer I O Error On Device
top Buffer I/O errors up vote 0 down vote favorite I notice that when I unmount my external HDD I sometimes getting messages in my logs which saying: Buffer I/O error on device sdX, logical block XX Where the X stands for the device for example: sdc.

Of late, the installation error on is failing with the error: "Buffer I/O error on device sda2, logical block 66326416" and series of such messages displayed on screen, causing the installation to fail. Found this failure is observed for a new set of seagate HDDs. On the same server with new Seagate HDD, RHEL5 is installed successfully (ruling out HDD hardware error). I tried to load all the drivers that are there in RHEL5, but that was failing too. Am looking for pointers to narrow down the issue. error on device Thanks in advance.

The issue is resolved by replacing the isci driver with megasr (my raid controller driver) in initrd (that is used while installation). When isci.ko driver detected my Seagate HDD, it was getting errors during installation. After replacing isci.ko with megasr driver, the installation went fine. share|improve this answer answered Oct 5 '13 at 6:01 keersan 14 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.
