In theory what you did was cut the array size to only use 9 KB of each device, then reshaped THAT tiny array from 8 to 9 devices, with the rest left completely untouched. So you could try removing the "new" disk, then try --create --assume-clean with old devices only and --raid-devices=8. But I'm not sure how you would get the device order right. Ideally what you can hope for, is you would get the bulk of array data intact, only with the first 9 KB of each device *(8-2), so about the first 54 KB of data on the md array, corrupted and unusable. It is likely the LVM and filesystem tools will not recognize anything due to that, so you will need to use some data recovery software to look for and save the data. -- 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
