I have been suffering from a crash and dump for some time now when shutting down my AMD Threadripper TR4 system. I think, but am not entirely sure, that the issue is with software raid. The system does its usual shut down tasks and then somewhere between shutting down the virtual machines (none of which were running/had been started) and the disks doing their shutdowns (not sure what to call it, but its nearly the last thing that happens before power off but it mentions each disk) I get a crash dump to the console. The only camera I have is on a really cheap phone, and its so bad that I can't pause the scrolling video (or the video is out of focus because it loses focus when the screen blanks before the output) to see what the error messages are because its just a blur. Is there anyway to get/print/transmit the log in real time to some external "thing" such as another pc on the network as by the time the crash happens the array (with the log files) must be down because there is nothing in the log files. No errors, shutdown messages, or shutdown log (is there even such a thing as a shutdown log?). Normally when something like this happens (which is increasingly rare) I just let it ride and usualy some new kernel eventually fixes it. The problem doesn't seem to corrupt anything so where ever the issue is (mdadm or otherwise) its not a huge deal... just I'd like it to stop because I hate seeing the crash dump and thinking "oh, there it goes again". This has been happening for at least 6-12 months (give or take) so its a long standing issue. (PS its debian testing/bookworm but the same issue happened with bullseye.) I guess if there is no such thing as re-directing the output to a network device, is it possible to move the log files to a non-raid device or an external usb? Does debian even have a shutdown log file? Thanks in advance, Jon.
