Will GFS work well in a cluster system that hosts a wide range of storage devices such as disk array, hard disk, flash and USB devices? Since these devices have very different performance and reliability behaviors, it could be a challenge for any CFS, right? I read from somewhere that GFS doesn't support multiple writers on the same file simutaneously. Is this true?
