 .TP
+.BI agskip= value
+Specifies the allocation group, (AG) for a new file, relative to the
+start of the last created file. agskip has the opposite effect of the
+rotorstep system tunable parameter.  Each new file to be placed in the
+location lastAG + agskipValue, where lastAG is the allocation group
+of the last created file.
+
+For example, agskip=3 means each new file will be allocated three AGs
+away from the starting AG of the most recently created file.
+
+The agskip mount option disables the rotorstep system tunable parameter.
+.TP
 .BI allocsize= size
