Server HDD activity, processes

Hello all!

Recently my server has been acting kind of weird, at random times the HDD start growling like nobody's business when nobody should be on there. I apt'ed Mon but it only shows that the HDD is in use which I can hear by myself with no software . So I was wandering is there something that will show me what process is making my HDD grawl, preferably with no kernel patches.

How about the logs is it generating too much logs ? Have you been watching the processes and do you have monitors for your HDD activity ? You probably already know but top, htop, conky and some other tools of the same kind can give you some info on fly about what is going on. I hope this helps.

iotop if you happen to be on the system at the time.
collectl will keep the stats per pid and can be queried after the event. If it's not a process (kernel,interrupt handler, ...) things get more difficult. Check the easy stuff first.

For a quick and dirty, iotop is good - plus it does have a batch mode if you need to catch things happening before you can get to it.
