I have a 50TB SAN device, which inturn has two partitions. One of the partition is a gfs2 configured to be shared between two nodes. However, I'm having trouble mounting this partition on one node, but not on the other one.
When I try to mount it I get the follwing error,
gfs_controld join connect error: error mounting lockproto lock_dlm
I figure it has something to do with cman as it says that it failed to get dbus connection right, but this service looks fine in the other node. Below is the output from cman service on the problematic node.

Here is the LSB header section from cman service file for your reference,(The LSB comment headers of cman had corosync $remote-fs as Required-Start/Required-Stop. Since *_gfs2.mount are in remote-fs.target and needs to be started after cman and corosync, this is impossible to satisfy. Therfore, I've removed $remote_fs in /etc/init.d/cman and /etc/init.d/corosync)
!/bin/bash
cman - Cluster Manager init script
chkconfig: - 21 79
description: Starts and stops cman

I'm not sure what is causing this problem. Any help will be greatly appreciated.
For your reference, I'm using
gfs2-cluster v 3.1.3-1.2
kernel v3.16.0-4-amd64
Debian 8
I'm new to these waters so kindly bear with me if I've missed something and please let me know if you need more information from my side.
Thank you very much!
Cheers,
