Xsan: Fragmentation

Xsan volumes can get fragmented.  This can cause the performance to move to a grinding halt.  Dropped frames, slow copy times, even volume corruption are common side effects.  So, to defrag the volume you can use snfsdefrag.  This command-line tool will defrag volumes or files.  You can even specify what to do with the fragmented data, giving you a way to move data between storage pools…
