nraygun Posted July 8 Share Posted July 8 On a Dell R710 that's been reliable with 6.12.8. Diags attached and syslog server setup. Woke up this morning to a parity check running and had been runnning for 6 hours. Nothing in the syslog shows any reason. I have macvlan setup and it's not been a problem. No mention of it going on the UPS and no other indication of what lead up to what appears to be a reboot. Any ideas? Is it macvlan? server-diagnostics-20240708-0935.zip Quote Link to comment
JorgeB Posted July 8 Share Posted July 8 macvlan can cause crash/hanging, but a server rebooting by itself is almost always a hardware issue, or bad power, unless you have a watchdog enabled, you can enable the syslog server and post that if it happens again, since macvaln usually leaves call traces, if that is the problem.

Mainfrezzer Posted July 8 Share Posted July 8 (edited) You forgot to include the logfile from the syslog server, theres nothing unusual to see in the diags, apart from the obvious issue with macvlan and bridging enabled. Without the syslog file from your syslog server, we would have to question the magic 8 ball Edited July 8 by Mainfrezzer Quote Link to comment
nraygun Posted July 8 Author Share Posted July 8 (edited) See syslog attached from yesterday into today. My R710 has two power supplies(and I have a 3rd spare). I don't see any macvlan call traces. What's this "watchdog" @JorgeB? Also, no VMs were running at the time. syslog20240708.txt Edited July 8 by nraygun Quote Link to comment

nraygun Posted July 9 Author Share Posted July 9 Is there a way to find out if this happened like in a log somewhere? Quote Link to comment
JorgeB Posted July 9 Share Posted July 9 Spontaneous reboots usually won't leave anything logged in Unraid, there may be something in the BIOS, if there's a system event log or similar. Quote Link to comment
nraygun Posted July 9 Author Share Posted July 9 I found out how to get to the web interface for iDRAC. Forgot I even had this available! I've been using a janky Java DRAC app to get to the boot screens. I looked around and don't see anything in any of the logs for this event. PSUs are good, System Event log shows stuff I've done(removed drive, open chassis, etc.). All of the "Platform Events" are set to "No Action" including the "Watchdog Critical Assert Filter". I'm at a loss! Quote Link to comment

nraygun Posted July 9 Author Share Posted July 9 Well, I got this R710 5 years ago and it's had a good run. This is the first time this has happened in this manner. Not bad for a system made 15 years ago. I was planning on upgrading my server hardware anyway (Intel i5). I guess it's time. Thanks for all the help! Quote Link to comment
