Hello,

Need your advise to understand more about the disk IO issue.
When we troubleshoot disk IO issue, how do we confirm whether the issue occurred due to faulty disk or application workload?

which parameter we need to check from iostat output to confirm the exact reason for the io issue?

If you want to check the disk IO issue, then remember that you are facing issues like slow transfer speeds, application delays, freezes, etc.).

  • If you can share the details like HDD, SSD, RAID config), their age, and any recent changes, it will help us to give more inputs.
  • Also, have you identified any particular applications or processes heavily using disk I/O?
  • As of now, we can suggest to use
    Code:
    smartctl
    (for HDDs) or vendor-specific tools to check for hardware errors or potential failures.
