Method Detail

syncDirectory

public static void syncDirectory(String dir)
                          throws IOException

This method fsyncs a directory. It should be called whenever a new file is created. It is required because syncing the child file doesn't ensure that the entry in the parent directory file has also reached disk. A side effect of not doing this is writes that disappear from the replica.

Parameters:

dir - the directory to be synced

Throws:

IOException
