How to check if a file is open anywhere in the cluster using GFS and lvm?

I wonder if it is possible to check if the file has already been opened by another node in the same GFS cluster. For example, the fuser command runs on a domain-wide basis in TruCluster. Can I request lock manager data using a command or API?
