Very high IO Statistics (Blocks Read/sec) even when nobody is using the server

Hello, My server shows high IO activity even when there is nobody using the server. When I see disk activity under "Disk Usage / Graphs", I usually see Blocks Read/sec in high thousands. I'm attaching a screenshot which I took - it shows md2 device doing 16,572 which I think is unusually high. Even sda device value is very high. Can anybody shed some light on what is going on here? Regards.

  Hello :) The following thread is a good resource for understanding which commands you can run to help better determine the cause of the high disk I/O: Troubleshooting High Loads On Linux Systems You may also want to report this issue to your data center to see if your hard drive is at the early stages of a failure. Thank you.
