I just woke up to all my lights on and my server off. It was a power cut, but... Checking the logs for Proxmox, it seems to have lost memory.. There were no logs for 10 days and when rebooting it said the system clock was off by as much (931,920 seconds = 10.7 days). What do? Anyone seen this before?
Thanks all, gonna replace the CMOS battery as suggested. Got a few in storage. π€
Your cmos battery is bad or your grid power was running below normal frequency
It is just a dead CMOS battery. So the clock had the wrong time, which in turn also causes the log entries to have the wrong time and date. Simply replace the battery. It is most likely of the CR2032 type.
In line with the possibility of your system's clock actually being wrong, can you correlate some other events in your logs to when you know they occurred? What about inside your VMs and CTs?
What kind of storage is it running on? Maybe the filesystem went read-only as another possibility to cmos battery issues.
Usually a cmos battery alone wouldn't cause something like logging to stop.
By any chance.... Your proxmox is not close to any source of big electromagnetic fields, right?
Close to big Transformator or electric motors, right?
Prepare yourself. The dark descent is coming
Switch to ZFS
Ext4 is way to vulnerable to power loss. It just keep a journal but it isn't nearly as robust as ZFS
