? 一天小明做了个系统，要装ceph，也许是Raid卡不支持JBOD,就只能做Raid0咯，表面看着好像没区别，大佬还会跟你讲做Raid0有毛线用，我在想也许他还不知道Ceph是替代什么的吧,像我这种小白，连JBOD是什么都不知道，（之前Cisco UCS 做Raid的时候看到过这个选项）。
?JBOD是存储领域中一类重要的存储设备，Low点的说法叫Raid卡直通，Just a Bunch Of Disks是JBOD的全名，奥，JBOD真的是只是一堆盘的缩写，23333。
?如果已经安装完系统，并且没有配置JBOD 而是做了RAID 插入新磁盘， 系统是看不到的，但是有些业务是不能重启的 ，但是你还想加盘，这就需要Megacli来搞事情了。
下载并安装
wegt https://docs.broadcom.com/docs-and-downloads/raid-controllers/raid-controllers-common-files/8-07-10_MegaCLI_Linux.zip
unzip 8-07-10_MegaCLI_Linux.zip
yum localinstall 8.07.10_MegaCLI_Linux/Linux\ MegaCLI\ 8.07.10/MegaCli-8.07.10-1.noarch.rpm目录根据情况修改
我们看下都生成了什么！！
rpm -ql rpm -ql MegaCli
/opt/MegaRAID/MegaCli/MegaCli
/opt/MegaRAID/MegaCli/MegaCli64
/opt/MegaRAID/MegaCli/libstorelibir-2.so.14.07-0/opt/MegaRAID/MegaCli/MegaCli64这个文件就是我们要用到的，
在我们通过megacli命令之前，我们需要遵循megacli概念。
适配器 - 我们要使用的物理控制器，由id（通常为0）表示。
机柜 - 物理机箱所附的物理驱动器，以id为代表，例如254,252等。
物理驱动器 - 附加到控制器的物理硬盘，由id，0,1,2,3等代表
虚拟驱动器 - 这些驱动器包含物理驱动器，并等同于由id，0,1,2,3等代表的RAID设备。
例如，如果我们的RAID 0超过3个物理驱动器，我们得到：
物理驱动器ID：0,1,2
虚拟驱动器ID：0
虚拟驱动器包含物理驱动器0,1和2，并包括突袭设备的设置，如RAID级别，条带大小等。
我们可以通过一个物理驱动器看到具有RAID 0的虚拟驱动器中的配置，我们有这种设置，因为物理驱动器连接到RAID控制器，并且为了将设备表示给系统，我们必须将其设置为兆位。
默认情况下，我们将在RAID 0中看到虚拟驱动器的所有物理设备。
使用lspci确保您的服务器已连接到RAID控制器。
lspci | grep -i raid我的输出
03:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2208 [Thunderbolt] (rev 05)这表明我这存在MegaRaid controller ；我可以愉快的使用MegaCli搞事！

| Size | RAID设备的大小，这个大小是实际可分配的大小 |
这就有点难了， 其实没什么卵用,记下来留着以后copy
/opt/MegaRAID/MegaCli/MegaCli64 -LdPdInfo -a0 | grep -E "Virtual Drive:|Slot Number:" | xargs | sed -r ‘s/(Slot Number:)(\s[0-9]+)/\2,/g‘ | sed ‘s/(Target Id: .)/Physical Drives ids:/g‘ | sed ‘s/Virtual Drive:/\nVirtual Drive:/g‘我的输出
Virtual Drive: 0 Physical Drives ids: 0,
Virtual Drive: 1 Physical Drives ids: 1,
Virtual Drive: 2 Physical Drives ids: 3,
Virtual Drive: 3 Physical Drives ids: 2,
Virtual Drive: 4 Physical Drives ids: 4,
Virtual Drive: 5 Physical Drives ids: 5,
Virtual Drive: 6 Physical Drives ids: 6,
Virtual Drive: 7 Physical Drives ids: 7,或者使用这个工具 "megasasctl"
前面主要是收集信息，有信息，才可以准确的创建
比如我们来一个
Adpater id: 0
Enclosure id: 252
Physical Drive ids: 3
Raid Level: 0命令参数
/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -rX[enclosure_id:physical_id,enclosure_id:physical_id] -aNX 是 RAID级别
N 是 adapter ID
举个栗子
/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdAdd -r0[252:3,252:4] -a0设备编号为3和4的磁盘，创建RAID0
来个RAID10
/opt/MegaRAID/MegaCli/MegaCli64 -CfgSpanAdd -r10 -Array0 [252:2,252:3] -Array1 [252:4,252:5] -a0删Virtual drives2
/opt/MegaRAID/MegaCli/MegaCli64 -CfgLdDel -L2 -a0常用选项
相关命令及其解析：

查看CPU个数 # dmidecode | grep "Socket Designation: CPU" |wc –l
查看出厂日期 # dmidecode | grep "Date"
查看充电状态 # MegaCli -AdpBbuCmd -GetBbuStatus -aALL |grep "Charger Status"
显示BBU状态信息 # MegaCli -AdpBbuCmd -GetBbuStatus –aALL

硬盘方面：
1、查看所有物理磁盘信息
MegaCli -PDList -aALL
2、查看磁盘缓存策略
MegaCli -LDGetProp -Cache -L0 -a0
or
MegaCli -LDGetProp -Cache -L1 -a0
or
MegaCli -LDGetProp -Cache -LALL -a0
or
MegaCli -LDGetProp -Cache -LALL -aALL
or
MegaCli -LDGetProp -DskCache -LALL -aALL
3、设置磁盘缓存策略
缓存策略解释：
WT (Write through
WB (Write back)
NORA (No read ahead)
RA (Read ahead)
ADRA (Adaptive read ahead)
Cached
Direct
例子：
MegaCli -LDSetProp WT|WB|NORA|RA|ADRA -L0 -a0
or
MegaCli -LDSetProp -Cached|-Direct -L0 -a0
or
enable / disable disk cache
MegaCli -LDSetProp -EnDskCache|-DisDskCache -L0 -a0
4、创建/删除 阵列
4.1 创建一个 raid5 阵列，由物理盘 2,3,4 构成，该阵列的热备盘是物理盘 5
MegaCli -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct -Hsp[1:5] –a0
4.2 创建阵列，不指定热备
MegaCli -CfgLdAdd -r5 [1:2,1:3,1:4] WB Direct –a0
4.3 删除阵列
MegaCli -CfgLdDel -L1 –a0
4.4 在线添加磁盘
MegaCli -LDRecon -Start -r5 -Add -PhysDrv[1:4] -L1 -a0
意思是，重建逻辑磁盘组1，raid级别是5，添加物理磁盘号：1:4。重建完后，新添加的物理磁盘会自动处于重建(同步)状态，这个 时候 fdisk -l是看不到阵列的空间变大的，只有在系统重启后才能看见。
5、查看阵列初始化信息
5.1 阵列创建完后，会有一个初始化同步块的过程，可以看看其进度。
MegaCli -LDInit -ShowProg -LALL -aALL
或者以动态可视化文字界面显示
MegaCli -LDInit -ProgDsply -LALL –aALL
5.2 查看阵列后台初始化进度
MegaCli -LDBI -ShowProg -LALL -aALL
或者以动态可视化文字界面显示
MegaCli -LDBI -ProgDsply -LALL -aALL
6、创建全局热备
指定第 5 块盘作为全局热备
MegaCli -PDHSP -Set [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0
也可以指定为某个阵列的专用热备
MegaCli -PDHSP -Set [-Dedicated [-Array1]] [-EnclAffinity] [-nonRevertible] -PhysDrv[1:5] -a0
7、删除全局热备
MegaCli -PDHSP -Rmv -PhysDrv[1:5] -a0
8、将某块物理盘下线/上线
MegaCli -PDOffline -PhysDrv [1:4] -a0
MegaCli -PDOnline -PhysDrv [1:4] -a0
9、查看物理磁盘重建进度
MegaCli -PDRbld -ShowProg -PhysDrv [1:5] -a0
