ubuntu server 14.04 添加新硬盘
作者：互联网
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：

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
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors

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)
Stride=0 blocks, Stripe width=0 blocks
122101760 inodes, 488378390 blocks
24418919 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
14905 block groups
32768 blocks per group, 32768 fragments per group

Superblock backups stored on blocks:

102400000, 214990848
Allocating group tables: done
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.
