Linux中格式化和挂载

一 格式化实战

[root@localhost ~]# ls -l /dev/sdb*

brw-rw---- 1 root disk 8, 16 Jul 22 09:10 /dev/sdb

brw-rw---- 1 root disk 8, 17 Jul 22 09:10 /dev/sdb1

brw-rw---- 1 root disk 8, 18 Jul 22 09:10 /dev/sdb2

brw-rw---- 1 root disk 8, 19 Jul 22 09:10 /dev/sdb3

brw-rw---- 1 root disk 8, 21 Jul 22 09:10 /dev/sdb5

brw-rw---- 1 root disk 8, 22 Jul 22 09:10 /dev/sdb6

[root@localhost ~]# mkfs.ext3 /dev/sdb1

二 挂载实战

[root@localhost ~]# mkdir -p /mnt/sdb1

[root@localhost ~]# mount /dev/sdb1 /mnt/sdb1

[root@localhost ~]# umount /mnt/sdb1/

如果要使得挂载永久生效

[root@localhost ~]# vim /etc/fstab
