I've encountered a strange issue. I had to change the time on my Linux RHEL cluster system. I've done it using the following command from the root user:

date +%T -s "10:13:13"

After doing this, some message appeared relating to <emerg> #1: Quorum Dissolved (however I didn't capture the message completely).

In order to investigate the issue I looked at /var/log/messages and I've discovered these errors.

Below is the output of few commands I got when tried to investigate the issue, however I don't have enough knowledge to make use of this information.

I tried to search through the internet and found out a quite similar issue here. However, for some reason I am not able to access the bug on bugzilla. The link to the bug is here
