Rebuild the Software RAID Array after a Drive Replacement

After a disk replacement on my server I need to rebuild the software array. I have had a look at the guide supplied by 1and1 but it does not correspond to what I am seeing in linux. [login to view URL] Here is what I am seeing: According to the guide they should be marked with an F as failed. I get: rescue:/# cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] [fault y] md1 : active raid1 sda1[0] 4194240 blocks [2/1] [U_] md3 : active raid1 sda3[1] 970470016 blocks [2/1] [_U] unused devices: <none> And fdisk -l is: rescue:/# fdisk -l Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc05267b6 Device Boot Start End Blocks Id System /dev/sda1 2048 8390655 4194304 fd Linux raid autodetect /dev/sda2 8390656 12584959 2097152 82 Linux swap / Solaris /dev/sda3 12584960 1953525167 970470104 fd Linux raid autodetect Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x55555555 Disk /dev/sdb doesn't contain a valid partition table Disk /dev/md3: 993.8 GB, 993761296384 bytes 2 heads, 4 sectors/track, 242617504 cylinders, total 1940940032 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md3 doesn't contain a valid partition table Disk /dev/md1: 4294 MB, 4294901760 bytes 2 heads, 4 sectors/track, 1048560 cylinders, total 8388480 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/md1 doesn't contain a valid partition table Disk /dev/mapper/vg00-usr: 4294 MB, 4294967296 bytes 255 heads, 63 sectors/track, 522 cylinders, total 8388608 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/vg00-usr doesn't contain a valid partition table Disk /dev/mapper/vg00-var: 859.0 GB, 858993459200 bytes 255 heads, 63 sectors/track, 104433 cylinders, total 1677721600 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/vg00-var doesn't contain a valid partition table Disk /dev/mapper/vg00-home: 6442 MB, 6442450944 bytes 255 heads, 63 sectors/track, 783 cylinders, total 12582912 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/vg00-home doesn't contain a valid partition table So I thought maybe I just need to add the partitions of the new drive to the correct arrays. But there is nothing in [login to view URL] Please help. All my clients websites were on here and I have no backup. Thanks.
