      Work Description: clebertsuconic commented on pull request #2782: ARTEMIS-2441 Separate Lock Files
URL: https://github.com/apache/activemq-artemis/pull/2782
 
 
   Certain devices or file systems won't support record level locking.
   For that reason I am changing FileLockNodeManager to use separate files (one for each position) instead of using tryLock(position);
   A good example for this would be cephFS where channel.tryLock or channel.tryLock works but it fails at a record level.

> Some file systems don't support positional locking (or record level).
>  
> A current example I bumped into is ceph-fs, however, I have had issues with record locking before with certain NFS versions, GFS and others.
>  
> To make things better, I'm just splitting the locks to separate files, and everything should still work the same while allowing these devices to work seamless.
