【原創】Linux基礎之掛載硬盤

1 查看哪些硬盤沒有掛載

# fdisk -l

Disk /dev/vdb: 107.4 GB, 107374182400 bytes, 209715200 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

2 將新硬盤分區

# fdisk /dev/sdb
Welcome to fdisk (util-linux 2.23.2).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

3 指定分區的文件系統格式

ext2

# mke2fs /dev/sda1

ext3

# mke2fs -j /dev/sda1

ext4

# mke2fs -t ext4 /dev/sda1

3.1 查看各個分區的文件系統格式

# parted -l
# file -s /dev/sda1
# df -T

4 掛載分區到目錄

# mkdir /test
# mount /dev/sda1 /test

4.1 永久掛載

# vi /etc/fstab

/dev/sda1 /test ext4 defaults 1 1

5 查看目錄以及分區

# df -h
