December 27, 20232 yr I few months ago I was having having a recurring issue where my Unraid server would "disappear" from my network. Despite having not been shut down or turned off in any way I would no longer be able to connect to it and it would no longer appear in my router's list of connected devices. I thought it must be hardware or cable issue until I ran Fix Common Problems and it suggested I change a setting within Unraid (something to do with IPVLAN or MACLAN or something like that?). That completely fixed the problem and my server has been up for months without issue. Unfortunately it happened again about a week ago and then it happened again a day or two ago whilst I was away from home. The only way to restart the server is to hold the power button down until it kills the power and then boot up again which I hate doing because I know it can damage things. After rebooting just now i'm concerned that I may have damaged my NVME cache drive because it is being reported as "unmountable". I've tried doing a clean reboot but there is no change. The screenshots below show (I apologize for the poor quality, my phone sucks) what the console was displaying after the latest crash but before i killed the power and rebooted. https://imgur.com/a/nbHCv03 https://imgur.com/a/BWPF4SG The screenshot below just shows the error message from my cache drive. https://imgur.com/a/mpOeY2K I've downloaded the diagnostics and the log files but I haven't included them because i'm not sure what the "standard" way of including them in a post is. If someone could let me know i'll update this post with them. Thanks. tower-diagnostics-20231227-1225.zip tower-syslog-20231227-1226.zip Edited December 27, 20232 yr by ChutneyBadger
