一、創建虛擬機
1.FreeNAS 是基於 FreeBSD 的
2.
3.
4. 操作系統版本選擇“FreeBSD“
因為我下載的 FreeNAS 的版本是 32 位的，所以這里選擇 “FreeBSD”。
如果你下載的 FreeNAS 的版本是 64 位的，要選擇 "FreeBSD 64位"。
5.
6.選擇處理器
7. 內存配置為 1G 就夠用了
8.
9.
10. 虛擬磁盤類型-->SCSI(S)
11.
12. 磁盤大小設置為 10G 就夠用了，因為這塊盤上僅安裝 FreeNAS 系統，不需要太大空間。
13.
14. 點擊“自定義硬件”
15. 刪除不必要的設備，如 USB 控制器、聲卡。
16. 點擊“關閉”
17. 點擊“完成”
18. 點擊 “編輯虛擬機設置”，添加用於存儲數據的硬盤。
19. 點擊 "添加"
20. 點擊 "硬盤" --> 點擊 "下一步"
21. 選擇 "SCSI(S)" --> 點擊 "下一步"
22.
23. 磁盤容量設置為 100G
24. 點擊 "完成"
25. 重復 19-24 的步驟，再添加 3 塊同樣的磁盤，添加完成后入下圖所示。
二、安裝 FreeNAS
26.
27.
28. 選擇大小為 10G 的硬盤
29. 選擇 "Yes"，鍵入回車確認。
30.
31.
32.
三、配置 FreeNAS
33.
34.
35.
36.
37.
38. 確認 FreeNAS 可以和宿主機通信
39. 在瀏覽器地址欄中輸入 http://192.168.147.111，通過 WEB 頁面管理 FreeNAS。
40. 右上角 Alert 圖標有告警，點擊查看，提示你修改 admin 用戶密碼。
41.
42. 修改 admin 用戶密碼
43. 密碼修改成功
44.
45. 添加卷
卷類型說明：
- Stripe: 至少需要一個磁盤
- Mirror: 至少需要兩個磁盤
- RAIDZ1: 至少需要三個磁盤
- RAIDZ2: 至少需要四個磁盤
- RAIDZ3: 至少需要五個磁盤
- log device: 至少需要一個專用設備，建議使用快速，低延遲，電源保護的SSD
- cache device: 至少需要一個專用設備，建議使用SSD
在添加卷按鈕警告說， 現有的數據將被清除。換句話說，創建新卷將重新格式化選定的磁盤。如果要保留現有數據，請單擊“ 取消”按鈕並參考 導入磁盤和導入卷來查看是否支持現有格式。如果是，請執行該操作。如果當前存儲格式不受支持，則需要將數據備份到外部介質，格式化磁盤，然后將數據恢復到新卷。
4 塊硬盤，用 RaidZ2 方式。
46.
47.
48. 開啟 iSCSI 服務
49.
50. 12 ≤ 密碼長度 ≤ 16
51.
52.
53.
54.
55.
56.
57.
58.
59.
60.
61.
62.
63.
64.
65.
66.
67.
68.
69. 在 iSCSI 屬性中開啟 CHAP 驗證，選擇組1。
三、Winodws 客戶端配置
這里以 Winodws 7 為例
70.
71. 點擊 "發現門戶"
72.
73.
74.
75.
76. 點擊 "連接"
77. 點擊 "高級"
78.
79.
80.
81.
82. 點擊 "取消"
83. 可以看到 iSCSI 磁盤了
二、linux客戶端連接iscsi共享存儲
#安裝配置 iscsi-initiator
- [root@localhost ~]# yum -y install iscsi-initiator-utils
- [root@localhost ~]# service iscsid start
#連接到iscsi共享存儲

FreeNas11.04 配置iscsi
1、全局配置
2、采用不認證的方式
3、配置后的效果
4、配置認證網絡
5、ALL 或192.168.1.1/24 (某一網段)
6、配置共享賬號
配置共享賬號效果如下：
7、配置Targent不認證方式訪問
8、配置共享目錄名稱，位置，大小，硬盤RPM.
9、Extents配置完成效果圖
10、設置Associated Targets
11、點發現（Discovery）---->Discover Portal:輸入IP和端口號--->ok。（其它地方直接用默認設置，即可）
12、Targets(查看連接狀態）
13、點磁盤管理，會彈出（檢測到了新硬盤），指定GPT格式，再分區格式化，即可使用。
、
如果之前掛載過相同的iscsi磁盤，再掛載時會報錯，只需點再Rescan Disks即可，修復。
14、linux下Targets連接方法
#注意他們的端口號是不一樣的(備注：默認3260時，可以不指定端口號 )
[root@template ~]# iscsiadm -m discovery -t sendtargets -p 192.168.1.140
#如果改了端口號，在后面要指定端口號
[root@template ~]# iscsiadm -m discovery -t sendtargets -p 192.168.1.140:3261
192.168.1.140:3261,2 iqn.gitlab.11.0
15、登錄到共享存儲（備注：這里測試登錄不同端口的共享盤）
[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、卸載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、實現iscsi自動掛載磁盤
- Fedora25設置開機自動掛載
#配置iscsi自動發現
cat /etc/iscsi/initiatorname.iscsi
InitiatorName=iqn.netcloud.11.0
#重新啟動服務
systemctl restart iscsid
systemctl status iscsid
systemctl enable iscsid
#設置開機自動掛載
[root@next-cloud-server ~]# vi /etc/rc.d/rc.local
#!/bin/sh
#mount iscsi disk 5TB
sleep 10
mount -t xfs /dev/sda /data
#授權
chmod +x /etc/rc.d/rc.local
#添加服務

18、掛載分區5T
分區
fdisk /dev/sda
g #大於5tb
再回車分區到完成
partprobe
mkfs.xfs -f /dev/sda
mount -t xfs /dev/sda /data/
