RBD export works great, sometimes too great and can overload the disks it's writing too, if those disks happen to be serving say VM's then goodnight VM.

Solution - Use throttle

Example - Export at 50MB\s

1rbd export volumes/volume-371b6662-1bc2-4dad-8545-c30ec1f0bfce - | python /root/throttle.py --bandwidth=52428800 > /data/MyExportedImage.img
