物理服務器Linux下軟RAID和UUID方式掛載方法--Megacli64

其它 log ron 軟件 sas 通過命令 sequence bios 單獨

一、業務部門需求說明:公司最近來了一批服務器,用於大數據業務部署。數據節點服務器由14塊物理磁盤,其中有2塊是900G的盤,12塊是4T的盤。在服務器系統安裝時,進入系統的BIOS界面:1)將2塊900G的磁盤做成raid1用作系統盤2)將其中的2塊4T的磁盤做成raid1,分別掛載到/data1和/data2用作大數據日誌存儲;3)另外的10塊4T的磁盤在系統安裝時沒做raid也沒做分區,打算在系統安裝後,登錄到系統終端通過命令行進行直接進行10塊盤的格式化,並分別掛載到/data3、/data4、/data5、/data6、/data7、/data8、/data9、/data10、/data11、/data12,用作大數據業務的數據盤,文件格式為ext4,采用uuid方式掛載,掛載屬性為noatime,nobarrier。

待服務器系統安裝後,登錄機器,使用"fdisk -l"命令,發現除了看到4塊做raid的盤,其余的10塊物理磁盤看不到:

這時候,需要用到一款管理維護硬件RAID軟件-MegaCli,它可以通過它來了解當前raid卡的所有信息,包括 raid卡的型號,raid的陣列類型,raid 上各磁盤狀態,等等。操作記錄如下:

1)下載及安裝MegaCLI工具
下載地址:https://pan.baidu.com/s/1TAGHjTA19ZR8MGODaqy7Mg
提取密碼:msbq
 
下載到/usr/loca/src目錄下
[root@data-node01 ~]# cd /usr/local/src/
[root@data-node01 src]# ls
ibm_utl_sraidmr_megacli-8.00.48_linux_32-64.zip
[root@data-node01 src]# unzip ibm_utl_sraidmr_megacli-8.00.48_linux_32-64.zip
[root@data-node01 src]# cd linux/
[root@data-node01 linux]# ls
Lib_Utils-1.00-09.noarch.rpm  MegaCli-8.00.48-1.i386.rpm
[root@data-node01 linux]# rpm -ivh Lib_Utils-1.00-09.noarch.rpm MegaCli-8.00.48-1.i386.rpm
 
說明:安裝完畢之後MegaCli64所在路徑為/opt/MegaRAID/MegaCli/MegaCli64,在此路徑下可以運行MegaCli64工具,切換到其它路徑下則不能執行,
此時為了使用方便,可以考慮將/opt/MegaRAID/MegaCli/MegaCli64追加到系統PATH變量,或者像下面這樣做(建議):
[root@data-node01 linux]# ln -s /opt/MegaRAID/MegaCli/MegaCli64 /bin/MegaCli64
[root@data-node01 linux]# ln -s /opt/MegaRAID/MegaCli/MegaCli64 /sbin/MegaCli64
 
2)使用MegaCli64命令進行相關操作
先查看磁盤數量。如下可以看出,一共有14塊物理磁盤
[root@data-node01 linux]# MegaCli64 -PDList -aALL | egrep ‘Enclosure Device ID|Slot Number‘
Enclosure Device ID: 32
Slot Number: 0
Enclosure Device ID: 32
Slot Number: 1
Enclosure Device ID: 32
Slot Number: 2
Enclosure Device ID: 32
Slot Number: 3
Enclosure Device ID: 32
Slot Number: 4
Enclosure Device ID: 32
Slot Number: 5
Enclosure Device ID: 32
Slot Number: 6
Enclosure Device ID: 32
Slot Number: 7
Enclosure Device ID: 32
Slot Number: 8
Enclosure Device ID: 32

Slot Number: 10
Enclosure Device ID: 32
Slot Number: 11
Enclosure Device ID: 32
Slot Number: 12
Enclosure Device ID: 32

接著查看磁盤信息

如上命令結果信息中,註意查看"Firmware state"的狀態:
如果該狀態為Online,就說明該磁盤已被做成raid陣列,
如果該狀態為unconfigured(good),就說明該磁盤沒有被做成raid陣列,但狀態OK。
 
由上面命令可知,前2塊4T的磁盤做成了raid,其余10塊4T的磁盤沒有做raid,另2塊900G的磁盤做成了raid。
 
--------------------------------------------------------------------------------------
 
現在的做法是:
通過MegaCli工具將那10塊4T的磁盤分別做成raid0,然後格式化成ext4,並使用uuid方式掛載。
 
依次對第3-12塊盤做成raid0陣列,其中:
-r0表示做成raid0陣列,[32:2]中的32為Enclosure Device ID,5為Slot Number。
WB Direct:磁盤Write back
[root@data-node01 linux]# MegaCli64 -CfgLdAdd -r0[32:2] WB Direct -a0
[root@data-node01 linux]# MegaCli64 -CfgLdAdd -r0[32:3] WB Direct -a0
[root@data-node01 linux]# MegaCli64 -CfgLdAdd -r0[32:4] WB Direct -a0
[root@data-node01 linux]# MegaCli64 -CfgLdAdd -r0[32:5] WB Direct -a0
[root@data-node01 linux]# MegaCli64 -CfgLdAdd -r0[32:6] WB Direct -a0
[root@data-node01 linux]# MegaCli64 -CfgLdAdd -r0[32:7] WB Direct -a0
[root@data-node01 linux]# MegaCli64 -CfgLdAdd -r0[32:8] WB Direct -a0
[root@data-node01 linux]# MegaCli64 -CfgLdAdd -r0[32:9] WB Direct -a0
[root@data-node01 linux]# MegaCli64 -CfgLdAdd -r0[32:10] WB Direct -a0
[root@data-node01 linux]# MegaCli64 -CfgLdAdd -r0[32:11] WB Direct -a0
 
然後再次查看磁盤情況,發現"Firmware state"的狀態都為Online,即所有磁盤都在raid陣列中了。
[root@data-node01 linux]# MegaCli64 -PDList -aALL
 
然後使用"fdisk -l"就能發現所有的物理磁盤了
[root@data-node01 linux]# fdisk -l
