    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.
