We had trouble with reliability for small, actively-accessed files on a 
distribute-replicate volume in both GlusterFS 3.11 and 3.12.  It seems 
that the replicated servers would eventually get out of sync with each 
other on these kinds of files.  For a while, we dropped replication and 
only ran the volume as distributed.  This has worked reliably for the 
past week or so without any errors that we were seeing before: no such 
file, invalid argument, etc.
