ubuntu server 14.04 添加新硬盘

1 关机，安装新硬盘, 然后上电开机。

2 检查是否检测到了新硬盘：

~$ ls -l /dev/sd* 

brw-rw---- 1 root disk 8,  0  5月 23 09:20 /dev/sda
brw-rw---- 1 root disk 8,  1  5月 23 09:20 /dev/sda1
brw-rw---- 1 root disk 8,  2  5月 23 09:20 /dev/sda2
brw-rw---- 1 root disk 8,  5  5月 23 09:20 /dev/sda5
brw-rw---- 1 root disk 8, 16  5月 23 09:20 /dev/sdb

看到了新增加的硬盘为 /dev/sdb

3 查看新硬盘的参数：

~$ sudo hdparm -I /dev/sdb

4 进行分区，由于我要用这块2T的希捷硬盘做数据盘，因此我将整块硬盘分成一个主分区，不再细分成扩展分区，逻辑分区。现在的系统都是64位的，因此是可以支持2T的主分区。

~$ sudo fdisk /dev/sdb 

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x1ab94f32.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

The device presents a logical sector size that is smaller than
the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.

5 查看一下所有的硬盘：

~$ sudo fdisk -l

6 格式化硬盘，现在的Linux的文件格式都是ext4的格式了，记得几年前还有用ext3的格式。

~$ sudo mkfs -t ext4 /dev/sdb1 

mke2fs 1.42.9 (4-Feb-2014)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)

Writing inode tables: done                            
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

7 给新硬盘写个标签。

~$ sudo e2label /dev/sdb1 /ext4-2T-disk-1 

8 给一个挂载点：

mkdir /home/yourname/dir 

9 编辑 /etc/fstab文件：

gedit /etc/fstab 

or

sudo nano /etc/fstab 

在文件的最后一行加入：

LABEL=/ext4-2T-disk-1    /home/yourname/dir    ext4    defaults    0    2

10 挂载

~$ sudo mount -a 

11 这时候，你会发现挂载的盘，普通用户无法写入，需要授权

~$ sudo chown -R $(whoami) /home/yourname/dir

12 扩展硬盘工作完成了

13 新硬盘上新建svn根目录

在 /home/yourname/dir目录下新建svn目录，编辑 /etc/apache2/apache2.conf 添加如下内容后

<Location /svn2>                   ### need change here!!!
  DAV svn
  SVNPath /home/yourname/dir/svn   ### need change here!!!
  AuthType Basic
  AuthName "Subversion repository"
  AuthUserFile /home/svn_data/passwd
  Require valid-user
</Location>

重启apache2服务器

sudo service apache2 restart

14 新硬盘上新建ftp文件共享目录

在 /home/yourname/dir目录下新建share目录，编辑 /etc/samba/smb.conf，添加如下内容

[share_disk1]                        ### need change here!!!
    path = /home/yourname/dir/share  ### need change here!!!
    available = yes
    browseable = yes
    public = yes
    writable = yes

重启smb服务器

sudo service smbd restart

15 到此增加硬盘并做相关设置就结束了.
