FreeNAS 安装与配置(版本9.3 与11.04)

一、创建虚拟机

1.FreeNAS 是基于 FreeBSD 的

2.

3.

4. 操作系统版本选择“FreeBSD“

因为我下载的 FreeNAS 的版本是 32 位的,所以这里选择 “FreeBSD”。

如果你下载的 FreeNAS 的版本是 64 位的,要选择 "FreeBSD 64位"。

5.

6.选择处理器

7. 内存配置为 1G 就够用了

8.

9.

10. 虚拟磁盘类型-->SCSI(S)

11.

12. 磁盘大小设置为 10G 就够用了,因为这块盘上仅安装 FreeNAS 系统,不需要太大空间。

13.

14. 点击“自定义硬件”

15. 删除不必要的设备,如 USB 控制器、声卡。

16. 点击“关闭”

17. 点击“完成”

18. 点击 “编辑虚拟机设置”,添加用于存储数据的硬盘。

19. 点击 "添加"

20. 点击 "硬盘" --> 点击 "下一步"

21. 选择 "SCSI(S)" --> 点击 "下一步"

22.

23. 磁盘容量设置为 100G

24. 点击 "完成"

25. 重复 19-24 的步骤,再添加 3 块同样的磁盘,添加完成后入下图所示。

二、安装 FreeNAS

26.

27.

28. 选择大小为 10G 的硬盘

29. 选择 "Yes",键入回车确认。

30.

31.

32.

三、配置 FreeNAS

33.

34.

35.

36.

37.

38. 确认 FreeNAS 可以和宿主机通信

39. 在浏览器地址栏中输入 http://192.168.147.111,通过 WEB 页面管理 FreeNAS。

40. 右上角 Alert 图标有告警,点击查看,提示你修改 admin 用户密码。

41.

42. 修改 admin 用户密码

43. 密码修改成功

44.

45. 添加卷

卷类型说明:

  • Stripe: 至少需要一个磁盘
  • Mirror: 至少需要两个磁盘
  • RAIDZ1: 至少需要三个磁盘
  • RAIDZ2: 至少需要四个磁盘
  • RAIDZ3: 至少需要五个磁盘
  • log device: 至少需要一个专用设备,建议使用快速,低延迟,电源保护的SSD
  • cache device: 至少需要一个专用设备,建议使用SSD

添加卷按钮警告说, 现有的数据将被清除换句话说,创建新卷将重新格式化选定的磁盘。如果要保留现有数据,请单击“ 取消”按钮并参考 导入磁盘导入卷来查看是否支持现有格式。如果是,请执行该操作。如果当前存储格式不受支持,则需要将数据备份到外部介质,格式化磁盘,然后将数据恢复到新卷。

 

4 块硬盘,用 RaidZ2 方式。

46.

47.

48. 开启 iSCSI 服务

49.

50. 12 ≤ 密码长度 ≤ 16

51.

52.

53.

54.

55.

56.

57.

58.

59.

60.

61.

62.

63.

64.

65.

66.

67.

68.

69. 在 iSCSI 属性中开启 CHAP 验证,选择组1。

三、Winodws 客户端配置

这里以 Winodws 7 为例

70.

71. 点击 "发现门户"

72.

73.

74.

75.

76. 点击 "连接"

77. 点击 "高级"

78.

79.

80.

81.

82. 点击 "取消"

83. 可以看到 iSCSI 磁盘了

二、linux客户端连接iscsi共享存储

linux访问iscsi详细操作

#安装配置 iscsi-initiator

  1. [root@localhost ~]# yum -y install iscsi-initiator-utils    
  2. [root@localhost ~]# service iscsid start   

#连接到iscsi共享存储

  1. [root@localhost ~]# iscsiadm -m discovery -t sendtargets -p 192.168.1.230
  2. 192.168.1.230:3260,1 iqn.2011-03.org.example.istgt:iscsiwin8  
  3. 192.168.1.230:3260,1 iqn.2011-03.org.example.istgt:iscsilinux  

#登录到iscsi共享存储  

  1. [root@localhost ~]# iscsiadm -m node -T iqn.2011-03.org.example.istgt:iscsilinux -p 192.168.1.230:3260 -l   
  2. Logging in to [iface: default, target: iqn.2011-03.org.example.istgt:iscsilinux, portal: 192.168.1.230,3260] (multiple)  
  3. Login to [iface: default, target: iqn.2011-03.org.example.istgt:iscsilinux, portal: 192.168.1.134,3260] successful.

FreeNas11.04 配置iscsi

1、全局配置

 2、采用不认证的方式

 3、配置后的效果

4、配置认证网络

5、ALL 或192.168.1.1/24 (某一网段)

6、配置共享账号

配置共享账号效果如下:

7、配置Targent不认证方式访问

8、配置共享目录名称,位置,大小,硬盘RPM.

9、Extents配置完成效果图

10、设置Associated Targets

11、点发现(Discovery)---->Discover Portal:输入IP和端口号--->ok。(其它地方直接用默认设置,即可)

12、Targets(查看连接状态)

13、点磁盘管理,会弹出(检测到了新硬盘),指定GPT格式,再分区格式化,即可使用。

如果之前挂载过相同的iscsi磁盘,再挂载时会报错,只需点再Rescan Disks即可,修复。

 

14、linux下Targets连接方法

#注意他们的端口号是不一样的(备注:默认3260时,可以不指定端口号 )

[root@template ~]# iscsiadm -m discovery -t sendtargets -p 192.168.1.140

#如果改了端口号,在后面要指定端口号
[root@template ~]# iscsiadm -m discovery -t sendtargets -p 192.168.1.140:3261
192.168.1.140:3261,2 iqn.gitlab.11.0

15、登录到共享存储(备注:这里测试登录不同端口的共享盘)

[root@template ~]# iscsiadm -m node -T iqn.gitlab.11.0 -p 192.168.1.140:3261 -l

Logging in to [iface: default, target: iqn.gitlab.11.0, portal: 192.168.1.140,3261] (multiple)
Login to [iface: default, target: iqn.gitlab.11.0, portal: 192.168.1.140,3261] successful.

16、卸载iscsi

[root@next-cloud-server ~]# iscsiadm -m node -T iqn.netcloud.11.0 -u
Logging out of session [sid: 1, target: iqn.netcloud.11.0, portal: 10.0.101.6,3261]
Logout of [sid: 1, target: iqn.netcloud.11.0, portal: 10.0.101.6,3261] successful.

  

17、实现iscsi自动挂载磁盘

  • Fedora25设置开机自动挂载

#配置iscsi自动发现
cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.netcloud.11.0

#重新启动服务
systemctl restart iscsid
systemctl status iscsid
systemctl enable iscsid

#设置开机自动挂载
[root@next-cloud-server ~]# vi /etc/rc.d/rc.local
#!/bin/sh
#mount iscsi disk 5TB
sleep 10
mount -t xfs /dev/sda /data

#授权
chmod +x /etc/rc.d/rc.local

#添加服务
[root@next-cloud-server ~]# vim /usr/lib/systemd/system/rc-local.service

# This file is part of systemd.

[Service]

GuessMainPID=no

#添加下面两行代码,实现rc-local作为服务启动
[Install]
WantedBy=multi-user.target

#启动服务

systemctl daemon-reload

systemctl start rc-local.service   (备注:去掉这行)
systemctl enable rc-local.service

 

 参考:http://blog.csdn.net/u013372441/article/details/77414471

 

18、挂载分区5T

分区

fdisk /dev/sda

g   #大于5tb

再回车分区到完成

partprobe 

mkfs.xfs -f /dev/sda
mount -t xfs /dev/sda /data/
