July 31, 20223 yr I've been using Unraid for ~5 years. I almost always have a smoking gun when I have an issue, but this time, I'm totally lost. Hardware specs at the end. Basically, after a few days, my system goes unresponsive. I can't connect to the webui, or via ssh... and after connecting a monitor, the monitor display goes blank (not, that there's simply nothing displayed, the output actually goes dead, and the monitor displays that its searching for a signal). I can reboot, go through a parity check, and then things are fine for another few days. Logs are useless since I can't get to them. I'm not sure if there's an improved logging plugin that will keep crash files through a power-cycle -- that's what I really need. I thought it might've been a flaky Seagate drive (showing command timeouts but after replacing and rebuilding -- same issue persists. Okay, system specs: Model: Custom M/B: Dell Inc. 09WH54 Version A00 - s/n: /84V2QD2/CN7220066A010Q/ BIOS: Dell Inc. Version 1.3.6. Dated: 05/26/2016 CPU: Intel® Core™ i7-6700 CPU @ 3.40GHz HVM: Enabled IOMMU: Enabled Cache: 256 KiB, 256 KiB, 1 MB, 8 MB Memory: 64 GiB DDR4 (max. installable capacity 64 GiB) Network: bond0: fault-tolerance (active-backup), mtu 1500 eth0: 1000 Mbps, full duplex, mtu 1500 Kernel: Linux 5.15.46-Unraid x86_64 OpenSSL: 1.1.1o Connected drives are in the attached screenshot. Primary disk controller is an LSI MPT SAS2. Only important note is that the 4 OCZ drives are actually a single PCIe-attached SSD. It presents as a single 1TB drive. It's an unassigned device that I only use for quick transfers (not a cache drive) and Plex transcoding. Unraid is basically agnostic to it. Any idea how I can further diagnose this?
August 1, 20223 yr Your diagnostics might show something. If that's not the case, you should set up a syslog server and post that file after the next crash.
August 1, 20223 yr Author Diagnostics was my first stop. I'll setup a syslog server. I think I need to stream that log to another machine on the network to debug this, right? Will it work if I do it to the flash and crashes during a write?

You can already share the complete zip file in your next post, it might already provide a clue. 6 hours ago, FlexGunship said: I'll setup a syslog server.

Not an expert on the syslog server, but I can see benefits for each methods (share/remote/flashdrive). Another user with more experience with it will probably chime in.
