TimTool Posted December 26, 2023 Share Posted December 26, 2023 (edited) Hi and Merry Christmas to you all I have been running an Unraid server for about 2 months on some old hw. I'm having trouble getting the server "stable", it crashes every couple of days and I have not been able to figure out what causes this. When the server crashes I'm not able to ssh in to the server and the WEB interface is not working. Before I installed unraid I ran the memtest, did the preclear of the disks. Everything seamed ok. First I installed the 6.12.4 version and had some random crashes every other day. Last week I upgraded to 6.12.6. But the same behavior continues. The server is not under any heavy load. I have a couple of docker instances running - plex, jellyfin, pihole. Last thing I have changed to day (after the last crash this morning), was to change the "Docker custom network type" from macvlan to ipvlan I have no prior experience with unraid. So any help would be much appreciated. tower-diagnostics-20231226-1154.zip Edited December 26, 2023 by TimTool Typo.. Quote Link to comment
JorgeB Posted December 26, 2023 Share Posted December 26, 2023 Enable the syslog server and post that after a crash. Quote Link to comment
TimTool Posted December 26, 2023 Author Share Posted December 26, 2023 Will do, but do you mean enable a "Remote" syslog server or just "Mirror syslog to flash" ? Quote Link to comment

TimTool Posted December 26, 2023 Author Share Posted December 26, 2023 (edited) I have had the "Mirror syslog to flash" enabled for some time.. I have two files in the flash drive /boot/logs "syslog-previous" file from yesterday - was last modified 2023--12-25 17:26 and "syslog" file from today - was last modified 2023-12-26 10:53 Is this the files you mean?

Solution itimpi Posted December 26, 2023 Solution Share Posted December 26, 2023 Your system seems to be experiencing Macvlan related crashes which are known to eventually crash the server. As mentioned in the release notes you should either switch docker to using ipvlan, or if you want to continue using Macvlan make sure that Bridging is disabled for eth0. Quote Link to comment
TimTool Posted December 26, 2023 Author Share Posted December 26, 2023 @JorgeB & @itimpi, Thank you very much for the quick reply. I will use ipvlan and see if it resolves my problem. Quote Link to comment
