                          I am getting the following error when trying to set the Primary node for DRBD.

    'node1' not defined in your config (for this host).

I know this is related to DNS/Hostname/Hosts and the config clusterdb.res. I know this because I originally got an error when trying to start clusterdb.res if node1 didn't resolve correctly. So what confuses me is that I can start the clusterdb.res if either use:



*I have used this command on the hosts*

    hostnamectl set-hostname $(uname -n | sed s/\\..*//)

To make the hostname resolve to node1 instead of node1.localdomain

Or add node1.localdomain to the config, either works. But I have tried all combinations and can't seem to get this command to take :

    drbdadm primary --force node1 && cat /proc/drbd

**My Configs**

/etc/drbd.d/clusterdb.res

    resource clusterdb{
     	protocol C;
    	meta-disk internal;
 	    device /dev/drbd0;

    startup {
    	wfc-timeout 30;
    	outdated-wfc-timeout 20;
    	degr-wfc-timeout 30;
    }

    net {
    	cram-hmac-alg sha1;
    	shared-secret sync_disk;
    }


    syncer {
    	rate 10M;
	    al-extents 257;
	    on-no-data-accessible io-error;
	    verify-alg sha1;
    }
    on node1 {
    	disk /dev/sda3;
    	address 192.168.1.216:7788;
    }
    on node2 {
    	disk /dev/sda3;
    	address 192.168.1.217:7788;
    }
    }

/etc/hosts :


    127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
    192.168.1.216 node1
    192.168.1.217 node2

/etc/hostname

    node#

My full write up ATM (wip) 

**Edits :**

     [root@node1 ~]# hostname
     node1
     [root@node1 ~]# cat /etc/hosts
     127.0.0.1   localhost localhost.localdomain localhost4      localhost4.localdomain4
     ::1         localhost localhost.localdomain localhost6      localhost6.localdomain6
     127.0.1.1     node1
     192.168.1.216 node1
     192.168.1.217 node2
     [root@node1 ~]#

Update: I have gotten this to work with LVM following this guide  exactly, so I think my issue actually lies with the following lines of code. But for now I think i will stick with LVM since it works, unless somebody else really wants to work on this. (My working LVM writeup)  

    device /dev/drbd0;
or

     device /dev/drbd0; 

The reason I say this, is I used the same hosts/hostname/shortname/ip_addr but LVM and it worked, but maybe I missed something the first time, I fixed in my new VM Template (I started from scratch to build LVM)
