Lost server from cluster

Post by jkettelhohn »

We had a server disappear from our 3 server cluster, I can SSH into the lost server and run commands and it thinks it is standalone suddenly. The other two servers think its gone too and my cluster is yellow. Looking on how I could get this server back to its cluster..

Also the web GUI for log003 I can't login to i can only seem to SSH into it.

To show the join a cluster page, remove the installed file and restart the host.
# rm /var/www/html/nagioslogserver/application/cache/installed
