[Drbd-dev] DRBD-filesystem interaction

[gniv at cs.umass.edu]

Hi,

I am a student who is looking to understand how DRBD interacts with the file
system for a project. I have looked through the code, but could use some help
(maybe a basic overview) figuring out the flow of operations from the time the
operating system opens a file and writes to it, to DRBD performing replication;
i.e. how DRBD listens to/intercepts system calls.
I understand what happens after DRBD gets the request, just looking for the
parts before that time.

Thanks,
Gal
