blockfile access patterns logging
Quoted 7 lines
Jens,
For some time I've wanted to log exactly what linux is reading and writing from my harddisk - for a variety of reasons. The current reason is that my very idle laptop writes to disk every once in a while (or reads, I don't know).
Have you mounted the fs with -o noatime?

Now, conceptually this should not be very hard, but I'd like to ask your thoughts on where I might insert some crude logging? There are lots of places that might be better or worse for some reason.

I'd love to be as close to the physical block device as possible, short of rewriting actual IDE drivers.
Any tips? Or is this idea crazy?
Thanks!
