Or maybe the remove bad block list code has some overflow bug which cuts each device size to 2048 GiB, without the array size reflecting that. You run RAID5 of five members, (5-1)*2048 would give you exactly 8192 GiB. -- With respect, Roman -- 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
