Hi everyone,
Over the last few months I've had numerous problems with my cache pool, with @JorgeB providing a lot of very helpful advice. A few weeks back I nuked the pool and started afresh, or at least I thought I had started with a clean new cache pool. The pool has performed flawlessly ever since then, however I've noticed that the second drive 'Cache 2' appears to have been on standby the entire time since starting over.
The fact that the second drive being on standby coincides with the absence of all the earlier issues may be confirmation that the second drive was the source of all my earlier issues, however I want to know why it's on standby and if it can be fixed?
What are the next steps I should take in root causing the problem?
