四、 /opt目录备份操作
由于要用新建的/dev/md/dsk/d5 挂到/opt下使用，我们在备份的时候就把/opt目录下的所有文件都恢复到/dev/md/dsk/d5挂载的一暂时目录/test下，出到对安全的考量，我们建议再做一份磁带的备份，以防不时之需。
操作方法和步骤：
1.ok boot -s
2.# ufsdump 0uf - /opt |(cd /test ; ufsrestore rf - )
3.# vi /etc/vfstab
/dev/md/dsk/d5 /dev/md/rdsk/d5 /opt ufs 1 no -
4.# mount /opt
5.# reboot
文件目录的复制，这样可以使用COPY过来的文件的属性和原来的是一样的。链接文件也会拷贝过来：
# cd /opt
# find . –print –depth |cpio –pdm /test
如果只是做目录的同步可以按上面的操作进行，只用非根（/）和非/usr目录的情形。
五、 磁盘分区操作
如果要对磁盘各片进行大小的调整可以按下面的操作方法进行操作。指定各个磁盘片的大小，如果要使用整个磁盘的话可以将除了片s2之外的所有片的空间都置为0就可以了。在使用片的时候可以直接使用s2就可以达到使用整个磁盘空间的目的了。不过，建议还是留一部分小的空间用供状态数据库使用。
