My Truenas scale Cobia installation is generally very stable and runs for weeks or months without any issues.
But today at c. 12 noon it "hung".
When I spotted this at c. 15:00 It was responding to network pings, but neither SMB nor admin web interface nor SSH would connect. The power button would not initiate a structured shutdown, so in the end I held the power button for 10-20secs and it turned off, and when I turned it on again it booted fine.
/var/logs/messages has a gap between 12:00.:14 and the reboot time. The admin Reports shows a gap in CPU load between 12:06:46 and the reboot time, for CPU temp after 11:49:51, for memory usage after 12:09:11, for zfs stats after 12:08:42, for disk activity on boot/apps pool SSD after 12:04:50, but for disk temps much earlier after 08:45:00.
I have no idea why the SMART disk temp logs stopped so early.
I would like to try to work out why it hung if possible. Can anyone suggest what I can do to find out more?
