Hi All,

I have 3x nodes cluster.

I saw error message upon issuing this command

What is happening?
 
Hi,

Can you see the status of rrdcached service if it has an error output?

Bash: 
systemctl status rrdcached
 
Hi Moayad,

This is the output.

Any suspicious?
 
Hi Moayad,

I rebooted 3 nodes, 1 by 1.
After the reboot, the errors still persist.

I left it for the weekend and today i checked, all are looking normal.

But i have questions,
1. what had happened? What was the cause?
2. Next time, what should i look for?


I'm sure, other members here should i have experienced this.
 
Hi Moayad and members,

Following up to my previous updates.

I also saw this message "Mar 03 17:04:46 em1 corosync[1382]: [KNET ] host: host: 3 has no active links". What does it mean?
