>
> The following procedure is applied if the file is locked:
> 1) take Node id from the lock Id.
> 2) see via discovery service if this node is alive.
> 3) if yes, return (we cannot lock the file).
> 4) if not: do a rollback:
> - delete all the blocks in "reserved" range from the data cache.
> - set reserved range to zero.
> - remove the lock from the FileInfo.
> The above procedure should be performed upon every attempt to take a lock,
> and (may be) periodically while traversing the file system.
