Resolving General Hardware Problems

Review the following sections to determine whether pool problems or file system unavailability is related to a hardware problem, such as faulty system board, memory, device, HBA, or a misconfiguration.

For example, a failing or faulty disk on a busy ZFS pool can greatly degrade overall system performance.

If you start by diagnosing and identifying hardware problems first, which can be easier to detect and all your hardware checks out, you can then move on to diagnosing pool and file system problems as described in the rest of this chapter. If your hardware, pool, and file system configurations are healthy, consider diagnosing application problems, which are generally more complex to unravel and are not covered in this guide.
