Newfs创建了文件系统，和在普通磁盘分区上操作没什么区别。我们需要注意到，这个文件系统的大小为34.5G，我们使用的是4块9G的磁盘，所以，这是正确的。现在，我们要mount起新建文件系统，还是和平时操作相同。如果我们想mount新建volume到目录”/vxrocks”，用一下命令：
# mount /dev/vx/dsk/datavol /vxrocks
#
就是这样啦！所有工作都完成啦。再一次强调，这是一种“艰苦的”方式。即使你很可能通常不用这个方法创建volume （我是使用这个方法的）但至少你需要理解对象（disk group, subdisk, plex, volume）是如何组合在一起的？以及它们之间是如何工作的？
第二课：Striped Volumes
请浏览下面的日志，看看你是否知道这是做什么的。我又从清除vmdisks开始，然后再来讨论它。开始吧：
