RRDC and RRD update errors

Stoiko Ivanov said:
is a different error - (no mention of the timestamps )...

depending on how important the historical data is - I would probably move the cache directory to a safe place and restart the services (that way recording should start fresh):
Code: 
cd /var/lib/rrdcached/
systemctl stop rrdcached
mv rrdcached rrdcached.bck
systemctl start rrdcached
systemctl restart pve-cluster

I hope this helps!

The problem gets fixed!!
Thanks a lot for your help.
 
Also running into this problem on 8.2.4, haven't found a solution yet. Restarting rrd service and deleting the dir does not even temp resolve for me.
 
Above solutions did not work for me either. It is a fresh install from the iso, weird...

edit: after some time (?!? 1hour?!?) it suddenly showed up...
(an hour after the renewal of the db folder and restarting of the services)

so maybe you need to be patient ;)

On my Proxmox Version 8.1.4

Attention: This operation will clear all your chart history.
Bash: 
systemctl stop rrdcached
mv /var/lib/rrdcached/db /var/lib/rrdcached/db.bck
systemctl start rrdcached
systemctl restart pve-cluster

If all its ok you can remove db.bck
Bash: 
rm -rf /var/lib/rrdcached/db.bck

Your solution worked on 8.2.4 until I reboot and the same issue persists (1970 on the graphs).
 
I have an Intel NUC that I am having the same issue with as of today. I have searched all over the forums and found a couple of suggestions from different proxmox threads but my graphs still show incorrect date/time.

I just updated to 8.4.1 today after the NUC was installed and setup.

The logs are full of this:

I also noticed that the BIOS wasn't updating the time after a reboot so we ended up having to replace it.

Probably a dead CMOS battery explains your situation.

I thought so as well. We switched to a different device and it is doing the exact same thing. I have also made sure that Chrony is running and the "date" and "hwclock" commands both say the same time within a few seconds due to static info and typing the different commands. I have verified that the network is setup for the correct timezone and is getting the correct time as well. I am doing updates on the new device now and I hope that everything is fixed once it reboots.

to my understanding this issue on topic of the thread only happens on single-node Proxmox VE, is that also the experience with others or was this a conclusion since rebuked ?

I have only setup single nodes so I can't know if it is also affecting clusters.
