先給硬盤建一個(gè)分區(qū)如下：

呵呵，不過有個(gè)問題，在slice 0下面再創(chuàng)一個(gè)分區(qū)slice 3，slice0下面還有自由空間也不能擴(kuò)展文件系統(tǒng)了，雖然照著提示做了fsck和lockfs也還是不行。刪了slice3后也還是不行。再把整個(gè)disk重新化分區(qū)，又可以擴(kuò)展了。

inode blocks/cyl group (922488) >= data blocks (4096)
number of cylinders per cylinder group (1) must be increased.
Note that cgsize may have been adjusted to allow struct cg to fit.
Filesystem is currently inconsistent. It must be repaired with fsck(1M)
before being used. Use the following command to do this:
fsck /dev/rdsk/c3t1d1s0
You will be told that the filesystem is already mounted, and asked if you
wish to continue. Answer `yes' to this question.
One problem should be reported, that the summary information is bad.
You will then be asked if it should be salvaged. Answer `yes' to
this question.
The filesystem is currently mounted read-only and write-locked. After
running fsck, unlock the filesystem and re-enable writing with
the following command:
lockfs -u /test
