How to use nbd to simulate slow disk to an existing data directory












0















I have come across the following thread explaining on how to use nbd and tirckle to simulate slow disk. But, my question is little different and hence creating a new question.



Can I simulate a slow hard drive?



Question:
My application is writing on to /var/data-dir and I would like to validate my application for slow disk by simulating slow disk to /var/data-dir.
Challenge: the directory specified contains app data containing heartbeat, session info etc.. Hence, it's important for me to mount nbd on to /var/data-dir. How may I use nbd to simulate slow disk here? I need to update lot of configuration files if I will have to mount nbd onto different location. Henge, I would like to avoid nbd mounting to different location.



Most of the example I have across for nbd are with new directory/location. Hence the question.
