+is the number of OSTs to stripe a file over. A

+of -1 means to stripe over all available OSTs.  The

+.I stripe-size
+of 0 means to use the filesystem-wide default stripe size (default 1MB).  The
+.I start-ost
+is the OST index (starting at 0) on which to start striping for this file.  A
+.I start-ost
+of -1 allows the MDS to specify the starting index and it is strongly
+recommended that the starting OST not be given, as this allows space and
