No, unless you have "---fs-features=local" when mkfs, apparently which 
is not your case.

I'd like to help you get DLM back, and seemly it's the only way out.
1. How many nodes of your cluster? and how many remaining?
2. Please show your corosync configuration - /etc/corosync/corosync.conf
3. And your resource agents configuration - crm configure show

I guess you may have only one remaining node, which cannot form quorum. So,
dlm resource agent cannot be started? If yes, you can change 
corosync.conf to
have "two_node: 1" and "wait_for_all: 0" according to "man votequorum". 
And then
try to start pacemaker again, or try "corosync-cfgtool -R" when cluster 
is already running.
Hope this can help;-)
