seems glusterfs 'should' handle the races with its locking translator, but like every distributed <add noun here>, they have their throughput limits.
so I guess it would depend on the load of your use case. A quick google search turned up some stories of race condition drama with GlusterFS ( https://www.google.com/search?q=glusterfs+race+conditions ), but I'm sure it would be just as easy to find similar for any file system.
