不知道是书上有些地方自相矛盾还是我的理解错误

首先书上是这么说的
You can only create state database replicas on slices that are not in　use.
You cannot create state database replicas on any slices in use.



然后，书上又举了一个例子
The following example shows how to use the metainit command to　create a RAID-0 volume:
# /usr/sbin/metainit -f d11 1 1 c0t0d0s0
d11: Concat/Stripe is setup
Caution – If encapsulating an existing file system in a RAID-0 volume,
both the numstripes and width arguments must be 1, or the data will be　lost.
The command line forces the creation of volume d11. Volume d11 creates　a concatenation composed of a single stripe, one slice wide, and it is　stored on the /dev/dsk/c0t0d0s0 disk slice.

Note – In this example, the root (/) file system is stored on the disk slice　/dev/dsk/c0t0d0s0. Because the root (/) file system is stored at that　location, you must use of the -f option to force the creation of a volume　on the mounted partition.

　　他在/dev/dsk/c0t0d0s0上做/usr/sbin/metainit ，但是他也说了/dev/dsk/c0t0d0s0是/所在的分区，但是前面又说只能在not in use的分区上做metainit

　　　自相矛盾还是理解错误？

后面说的是用metainit创建元设备metadevice时....你理解错误
