/dev/sdb 说明已经识别出第二块硬盘
[b]二、挂载硬盘[/b]
1、在本地硬盘中临时创建一个目录[code]#mkdir /opt/data/tmp1[/code]2、挂载第二块硬盘中的一个分区/dev/sdb1到tmp1[code]#mount /dev/sdb1 /opt/data/tmp1[/code]3、查看是否被挂载
[quote]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 2.0G 141M 1.8G 8% /
none 1014M 0 1014M 0% /dev/shm
/dev/sda2 4.0G 1.8G 2.0G 47% /opt
/dev/sda7 18G 168M 17G 1% /opt/data
/dev/sda5 4.0G 1.4G 2.4G 37% /usr
/dev/sda3 4.0G 2.1G 1.8G 55% /var
/dev/sdb1 3.9G 1.4G 2.3G 38% /opt/tmp/tmp1[/quote]
[b]三、卸载硬盘[/b]
#umount /dev/sdb1
