RAID 0（条带和串联）

1. 从 3 个磁盘的 S2 分片创建串联：

# metainit d1 3 1 c0t1d0s2 1 c1t1d0s2 1 c2t1d0s2

d1 - the metadevice
3   - the number of components to concatenate together
1   - the number of devices for each component.

2. 从 3 个磁盘的 S2 分片创建条带：

# metainit d2 1 3 c0t1d0s2 c1t1d0s2 c2t1d0s2 -i 16k

d2      - the  metadevice
1        - the number of components to concatenate
3        - the number of devices in each stripe.

-i 16k 条带段大小。

3. 创建三个，2个磁盘串联并将它们条带化在一起：

# metainit d3 3 2 c0t1d0s2 c1t1d0s2  -i 16k 2 c3t1d0s2 c4t1d0s2  -i 16k 2 c6t1d0s2 c7t1d0s2  -i 16k

d3     - the meatadevice
3       - the number of stripes
2       - the number of disk (slices) in each stripe
-i 16k - the stripe segment size.
