Linux has a distributed lock manager in kernel for the GFS2 file system.

I strongly suspect that Oracle's OCFS as well as ACFS both have 
(different) DLMs.

Veritas has it's Group Lock Manager that performs what I understand a 
DLM to do.

IBM's GPFS has a distributed lock manager.

I would be surprised to see any type of cluster that had shared access 
to disks that didn't have a DLM.

Apparently Microsoft's Cluster Server does not provide shared access to 
things and is instead exclusively single access.  Thus there is no need 
for a DLM.  Or so I quickly read.
