The errors on the filesystem are not related to the RAID setup nor the failure. You might have had those errors while the array was working. I suggest you install smartmontools and run smartctl -a /dev/sdx on each disk on the array and see if you have ATA or CRC errors. These indicate cable issues usually. SECTOR errors indicate physical damage on the disk (bad sectors). On Tue, Dec 15, 2009 at 2:09 AM, Tirumala Reddy Marri <tmarri@xxxxxxxx> wrote: > To be more specific.
