Hello,
First, I will start by saying I am not savvy when it comes to server issues. I am a project manager for a company that uses Kayako as an on-premise ticketing system. This morning, we're unable to log in to the site. It seems both the client side and our side yields no response. I have attached images of what I found for error messages that pertain to the VM, but I am unsure of how to resolve it.
I also found this error in the cluster error logs while logged into the server in PuTTY: Apr 20 00:42:45 nodel pengine[18133]: warning: Processing failed op monitor for res_VirtualDomain_Kayako on nodel: not running (7)
It's also worth a note that when I logged in to the server before, the IP address was 192.168.0.11, trying to log in to that did not work, then successfully logged into the server using 192.168.0.15. Weird as it seems like the site sort of just vanished over the weekend. Some help would be greatly appreciated as I am VERY MUCH a novice at this and haven't a clue what to do.

Re: DNS Server Issues
I see you have a 2 node cluster... It's more complex than it looks like.
What is the output of:
Also, you have a drbd , which is weak when in 2 node setup - there could be a split brain -> thus dataloss is possible.
If possible, find someone with cluster experience to fix the situation... It will be a slow process fixing it over the forum.
What is the output of:
Code: Select all
crm_mon -r1

Re: DNS Server Issues
But if your ip address has changed on the system, that could be enough to explain everything that you see.
The future appears to be RHEL or Debian. I think I'm going Debian.
