如上圖，加了三個(gè)磁盤

現(xiàn)在，先開始做raid0

工具 mdadm

命令常用參數(shù)? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ??

-C或--creat	建立一個(gè)新陣列	-r	移除設(shè)備
-A	激活磁盤陣列	-l 或--level=	設(shè)定磁盤陣列的級別
-D或--detail	打印陣列設(shè)備的詳細(xì)信息	-n或--raid-devices=	指定陣列成員（分區(qū)/磁盤）的數(shù)量
-s或--scan	掃描配置文件或/proc/mdstat得到陣列缺失信息	-x或--spare-devicds=	指定陣列中備用盤的數(shù)量
-f	將設(shè)備狀態(tài)定為故障	-c或--chunk=	設(shè)定陣列的塊chunk大小 ?，單位為KB
-a或--add	添加設(shè)備到陣列	-G或--grow	改變陣列大小或形態(tài)
-v	? ?--verbose 顯示詳細(xì)信息

分好區(qū)

[root@duwen113?~]#?mdadm?-C?/dev/md11?-l?0?-n?3?/dev/sdb1?/dev/sdc1?/dev/sdd1 mdadm:?Defaulting?to?version?1.2?metadata mdadm:?array?/dev/md11?started. [root@duwen113?~]#?mdadm?-Ds ARRAY?/dev/md11?metadata=1.2?name=duwen113.cn:11?UUID=6689430a:4d3a76e2:9a832442:bf61bdfa [root@duwen113?~]#

效果如下圖

生成配置文件

[root@duwen113?~]#?fdisk?/dev/md11[root@duwen113?~]#?ls?/dev/md* /dev/md11??/dev/md11p1 [root@duwen113?~]#

開始加密

測試一下加密是否成功

看到那個(gè)紅框了吧，是需要輸入密碼才可以進(jìn)去的 ? ? ? ?//紅框這里輸入密碼51cto.com
