Hi, I have a scenario in which I need to use a lock file to prevent multiple processes to run on the same directory concurrently. The processes could run on the same machine or on different machine, with a NFS filesystem.
If I understand correctly FilesystemLock works fine with different processes on the same machine, but since it uses a symlink to PIDs to identify the lock owner, it is not guaranteed to be safe on NFS. Is this the only issue with this scenario? In this case I guess it could be fixed by adding a machine identifier (hostname or some hash) to the name. Also, is there any possible concurrency problem with NFS atomicity?
