One of my servers is getting very high Disk I/Os. The problem is that the disk I/Os are constantly increasing. The server just have simple LAMP configuration and there shouldnt be any disk operation ideally.
Any help on how can I investigate as to what is causing this high disk I/O and how can I fix it. top / htop etc isnt giving me good information worth debugging
Thanks

Try use iotop to find active I/O process.
Also, try remount xvda with noatime option and add "iostat -dx 2" output from host system.
