[Gluster-users] AFR'd Namespace sets creation time on directory to 1970

Hi Krishna,

the servers have been restarted before this bug occurred, yes. Files in the directory in question have not been modified since the restart.
However, as I just noticed, the creation time on the directory is "fixed" when it's updated, e.g. you create a new file inside the directory.
