CENTOS7.4 分区 格式化 原

1. 查看磁盘

[root@yzb-centos72-3 ~]# fdisk -l Disk /dev/vda: 32.2 GB, 32212254720 bytes, 62914560 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 Disk label type: dos Disk identifier: 0x0009680e    Device Boot      Start         End      Blocks   Id  System /dev/vda1            2048     4194303     2096128   82  Linux swap / Solaris /dev/vda2   *     4194304    56623103    26214400   83  Linux 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

发现/dev/vdb这块未分区、格式化

2. 分区

[root@yzb-centos72-3 ~]# fdisk /dev/vdb 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. Device does not contain a recognized partition table Building a new DOS disklabel with disk identifier 0x20ea1593. Command (m for help):  输入m 查看

Command (m for help): m Command action    a   toggle a bootable flag    b   edit bsd disklabel    c   toggle the dos compatibility flag    d   delete a partition    g   create a new empty GPT partition table    G   create an IRIX (SGI) partition table    l   list known partition types    m   print this menu    n   add a new partition    o   create a new empty DOS partition table    p   print the partition table    q   quit without saving changes    s   create a new empty Sun disklabel    t   change a partition's system id    u   change display/entry units    v   verify the partition table    w   write table to disk and exit    x   extra functionality (experts only) Command (m for help):  输入n

查看  fdisk -l

已经分好区，但是未格式化

[root@yzb-centos72-3 ~]# fdisk -l Disk /dev/vda: 32.2 GB, 32212254720 bytes, 62914560 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 Disk label type: dos Disk identifier: 0x0009680e    Device Boot      Start         End      Blocks   Id  System /dev/vda1            2048     4194303     2096128   82  Linux swap / Solaris /dev/vda2   *     4194304    56623103    26214400   83  Linux 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 Disk label type: dos Disk identifier: 0x35bf8022    Device Boot      Start         End      Blocks   Id  System /dev/vdb1            2048   209715199   104856576   83  Linux

3. 格式化  mkfs -t ext3   或者  mkfs.ext3 

[root@yzb-centos72-3 ~]# mkfs -t ext3 /dev/vdb1 mke2fs 1.42.9 (28-Dec-2013) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) Stride=0 blocks, Stripe width=0 blocks 6553600 inodes, 26214144 blocks 1310707 blocks (5.00%) reserved for the super user First data block=0 Maximum filesystem blocks=4294967296 800 block groups 32768 blocks per group, 32768 fragments per group 8192 inodes per group Superblock backups stored on blocks:          32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,          4096000, 7962624, 11239424, 20480000, 23887872 Allocating group tables: done                             Writing inode tables: done                             Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done    [root@yzb-centos72-3 ~]# 

4. 挂载

先在根目录建data

[root@yzb-centos72-3 /]# mkdir data

然后挂载

 mount /dev/vdb1 /data

查看挂载后的目录

[root@yzb-centos72-3 /]# df -Th Filesystem     Type      Size  Used Avail Use% Mounted on /dev/vda2      ext4       25G  3.1G   21G  14% / devtmpfs       devtmpfs  3.9G     0  3.9G   0% /dev tmpfs          tmpfs     3.9G     0  3.9G   0% /dev/shm tmpfs          tmpfs     3.9G   57M  3.8G   2% /run tmpfs          tmpfs     3.9G     0  3.9G   0% /sys/fs/cgroup tmpfs          tmpfs     783M     0  783M   0% /run/user/0 /dev/vdb1      ext3       99G   60M   94G   1% /data

将挂载持久化到文件，开机自动挂载

/etc/fstab

vi /etc/fstab

# # /etc/fstab # Created by anaconda on Mon Jan  2 22:58:53 2017 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # UUID=381f5199-12a4-4d44-91af-be015a752145 /                       ext4    defaults        1 1 UUID=4b0d629d-79d8-43e3-82bd-8a7b98fcfb75 swap                    swap    defaults        0 0 /dev/vdb1   /data                                              ext3    defaults        1 1

TIP：

inux使用ntfs-3g 挂载NTFS分区

一、安装ntfs-3g:

sudo apt-get install ntfs-3g或者yum install ntfs-3g

二、fdisk -l查看磁盘设备点,挂载设备

mount -t ntfs-3g /dev/sdd4 /ntfs

如果需要开机自启动挂载，可以在vi /etc/fstab文件结尾添加需要挂载的NTFS盘，

添加命令如下：

/dev/sdd4 /ntfs ntfs-3g defaults 0 0
