while creating HA centos server, I installed new drbd although there was existing drbd. After the conflict, as depicted in below, I was not able to load the drbd module.
[root@NAS1 ~]# rpm -qa drbd
drbd-8.9.6-1.el6.monos.x86_64
[root@NAS1 ~]# service drbd start
Can not load the drbd module.
I 'm really new to structuring centos to HA form, so any advice related to using this module would be a great help.
Attached is are list of packages related to this
[root@NAS1 ~]# rpm -qa | grep drbd

It doesn't look like you have the kernel module installed; only the utils are listed above.
To install the kernel module from elrepo: yum install kmod-drbd84
