[SOLVED] Summary Graphs Empty with Wrong Date

[ririzarr]

New to Proxmox and looking for some guidance. I just built three hosts and configured them as a cluster. Two of them show data and correct time for the Summary graphs but one is empty with the wrong date. I've compared the date and time.

While trying to find a solution, I came across this thread https://forum.proxmox.com/threads/graph-date-wrong.122784/ describing a similar situation so I tried the command given by support - pvesh get /nodes/NODENAME/rrddata --timeframe hour

For the host in question, it returns the following error: RRD error: rrdcached@unix:/var/run/rrdcached.sock: rrd_fetch_r failed: mmaping file '/var/lib/rrdcached/db/pve2-node/pve01': Invalid argument

The other two hosts return a table of results.

Thank you!

Can you please post the output of: ls -l /var/lib/rrdcached/db/pve2-node/

Also, any other errors in the journal? journalctl -b

Thanks for the reply. I did some more digging and found that the following fixed the issue:

rm -r /var/lib/rrdcached/db
systemctl restart rrdcached.service

For anyone wondering, if this is still occurring for you (in 8.4.X) this worked for me as well. Had the issue in 8.4.1. Was also showing the date/time in the summary as the year 1969. Updated, still had the issue in 8.4.12 after the update completed. Removing the db and restarting as per @ririzarr fixed the issue.

Of course don't forget to wait a few minutes for actual data to appear in the graphs, but you should immediately see the year 1969 gone and the current date/time displayed.
