December 11, 20232 yr Hi everyone, this is a followup from my previous post. My Unraid host rebooted this morning without explanation, while files were being copied into the pool. The file copy was running overnight , before the unexpected restart. I have enabled coping the syslog to flash drive, so hopefully I have some information this time. Thank you to @itimpi for the advice. My setup is as follows: - 3 16TB drives in an encrypted ZFS storage pool. (Seagate EXOS) - 128gb USB as the sole array drive (I needed to have a drive in the array in order to create a ZFS storage pool in the 'cache', it isn't used). - VM and Docker disabled. MB: Supermicro X10SL7-F RAM: 32gb DDR3 ECC unregistered CPU: Intel Xeon®CPU E3-1271 v3 @ 3.60GHz PSU: Seasonic 80+ gold 750w My ram has passed Memtest86. It has also passed the Windows Memory Diagnostic and I have purchased and run Karhu Memtest - again no issues detected. Nevertheless, I suspect it is a RAM issue, my PSU is overkill and the PC never reaches above 45 C. syslog
