It is in fact showing a normal MBR with two partitions for device /dev/sda
Disk /dev/dm-0 doesn't contain a valid partition table
Disk /dev/dm-1 doesn't contain a valid partition table
Disk /dev/dm-2 doesn't contain a valid partition table
Disk /dev/dm-3 doesn't contain a valid partition table
Disk /dev/dm-4 doesn't contain a valid partition table
This is a normal message for fdisk of that era because it doesn't ignore the fact these are device mapper logical block devices, which do not normally ever have partition tables, you just format them. The /dev/dm-X designation is mapped to /dev/mapper/VGblah-LVblah. They are one in the same. There's nothing wrong here except possibly the presentation depending on the age of the tools.
