randommonth Posted August 15, 2023 Share Posted August 15, 2023 Hi guys, I have had issues with cache drive stability in the past when I was running dual SSDs in a pool. I reduced the cache down to a single drive and have experienced excellent stability for the last 6-9 months. I could not pin point the root cause but I suspect some of the SATA ports on my motherboard are loose or faulty. I upgraded to 6.12.3 about a week ago and have seen consistent re-occurrence of the cache instability. Every morning I'm waking to find the cache has degraded somehow overnight, either completely disappearing or simply being unreadable. I have managed to resolve quickly each time by shutting down and rebooting, sometimes needing to stop the array and reassign the cache to pool. Each time the cache has reappeared and worked fine. Find diagnostics attached. Thanks bigdaddy-diagnostics-20230816-0641.zip Quote Link to comment

randommonth Posted August 21, 2023 Author Share Posted August 21, 2023 Thanks again @JorgeB! It's taken me a few days to backup my cache but then when I performed the process this morning, I found the process didn't wipe my cache after all. I'll give it a few weeks to monitor for success before marking this as the solution. 1 Quote Link to comment
