Today I was unable to access the web interface, and SSH refused the connection. I checked SMB and that was fine. Hard reset. It booted ok. I checked Netdata and on Sun Dec 28th 21:30 iowait went to 92% and stayed there. I’m on 25.10.1 - Goldeye, and have been since it was released. Looks like I previously rebooted on Dec 20th, so about 7-8 days.
Hardware is a Terramaster T2-424, os on a small SSD, couple of 18TB drives, couple of 1TB and 2TB NVME drives, external Terramaster via USB, 18TB drive (for backup), couple of 512GB and 1TB NVMEs. 2.5Gb/s NIC (single in use). I newish to TrueNas, more at home with Azure storage, and 3PARs, so I won’t know exactly where to go to try to pin down what process was runaway.
