I have a DRBL server, basically an nfs fileserver, which I am rebuilding. I want to put the high i/o directories on a separate raid array for performance. Currently everything is under / in one raid array.
How can I tell which directories, obviously other than /home, are getting high reads and/or writes? Any tools to measure i/o per directory?
Thanks

Well there certainly might be better ways, but if iotop for example indicates a process is producing high file IO, lsof -p <pid> will show which file.

As for this, most likely one or several bad DIMMs (or possibly bad MB).

Thank you peter for the input...I don't think its the motherboard as I have 5 of these boxes and they all experiencing the same problem (running the latest bios). I tried switching the RAM around and did manual timing at 667 in the BIOS, hope this fixes the problem. Kingston won't be too happy if I tell them that there memory is not working in my systems specially when we talking about 512GB of memory. Let's see what happens, I will report back as I monitor this situation.
