Hi all, I have two 2TB disks half set up using raid 1 (full mirroring ?) and the other half using striping. very frequently my system, a kubuntu 11.10, hangs (gui is unresponsive). pressing alt-esc to popup the process monitor shows that key processes are hanging on disk-sleep. Often this is the flush daemon or the mdadm processes or sometimes just two or three applications. I have an i7 8GB disk with 64 bit linux. What might be causing this ? -- 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
