Option E is definitely worth a look. If the cache is not being utilized effectively, that could be causing a lot of unnecessary disk activity.

Let's prioritize investigating the cache utilization to see if that's the root cause of the disk I/O peaks.

Agreed. Checking the rate of change in Qcache_hits compared to Qcache_not_cached could give us some insights.

Good idea. If the cache isn't working well, it could be causing the disk stalls.

Haha, I bet the database admins are just taking a coffee break and blaming the system. But in all seriousness, Option C looks like it could be a good starting point.

I'm leaning towards Option D. Tracking the difference between the transaction ID counter and the purge status could help us identify any potential issues with the InnoDB purge process.

Option D seems like a good starting point. Let's investigate the InnoDB status values for any anomalies.

Option B seems like the way to go. Checking the redo log size and comparing it to the difference in log sequence numbers could give us some valuable insights into the disk I/O issues.
