At that point I was on kernel version .34 [trim /] What you are experiencing is typical of a hobby-level user who bought non-raid-rated drives and is now experiencing timeout mismatch array failures due to a lack of error recovery control. I suggest you search the archives for various combinations of "scterc", "URE", "timeout", and "error recovery". In the end, you almost certainly will need to either use "smartctl -l scterc,70,70" to turn on ERC in your drives, or use "echo 180 >/sys/block/sdX/device/timeout" to lengthen linux's standard driver command timeout. Anyways, when you check in again, please report the output of the following: 1) "mdadm -E /dev/sdX" for each member device or partition 2) "mdadm -D /dev/mdX" for your array 3) "smartctl -x /dev/sdX" for each member device 4) "cat /proc/mdstat" 5) "for x in /sys/block/sd*/device/timeout ; do echo $x $(< $x) ; done" 6) "dmesg" (trimmed to relevant md and sd* messages) 7) "cat /etc/mdadm.conf" Phil -- 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
