Design philosophy... There is no metadata server. When you look at timestamps in stat, you are seeing the real stat of the file. If you have "replica 2" then you have two files. The stat can come from either one. Mtime will be the modification time of the file referenced by the time on the server (not the client.) One of the strengths of GlusterFS is that it does not have the bottleneck/single point of failure of a single metadata server. -- Mr. Flibble King of the Potato People
