July 14, 20232 yr So I've got this issue that has happened twice in probably 6 months. My cache array is generally running great except for this one issue. I have only one single drive (not great I know - I plan to get a second one when budget allows). The drive is a 2TB NVME drive. Things will be running fine and then, randomly, the drive goes missing and the array goes offline. The server cannot see the NVME drive. Reboot does not fix it. The only thing that works is shutting off the server, opening it up and reseating the NVME. That brings it back online fine and on boot everything returns to normal. There appears to be also no errors in the logs when this happens. I have sys logging turned on and there's just nothing in the logs about it but that makes sense because the syslog is logging to the cache drive. I have temporarily moved the syslog share to my array so if this happens again I can hopefully see something in the logs. I've had temperature warnings in the past so I am also wondering if that is part of the reason the NVME shuts down. Has this happened to anybody else?
