Does GFS or GFS2 support millisecond timestamps?
Currently, gfs and gfs2 do not use milliseconds for files. They use seconds. This is to maintain compatibility with the underlying vfs layer of the kernel. If the kernel changes to milliseconds, we will also change. People don’t normally care about milliseconds, so milliseconds only become important to computers when doing things like NFS file serving. For example, to see if another computer has changed the data on disk since the time of the last known request. For GFS2, we’re planning to implement inode generation numbers to keep track of these things more accurately than a timestamp can.
