In the above output, we come to know that no RAID configuration is done on two hard drives sdb and sdc.Step 2 : Creating Partitions for RAIDNow create RAID partitions on hard drive sdb and sdc, with the help of
RAID (Redundant Array of Independent Disks) is a technology that uses multiple disk drives to improve performance and data redundancy. It combines multiple physical disk drives into a single logical unit. This tutorial explains RAID terminology and configuration steps in Linux. RAID Terminology The fo...

配置RAID 1 的步骤(以 Linux 为例): 准备硬盘:确保有两块相同容量和类型的硬盘。 安装mdadm:mdadm 是 Linux 下管理软件 RAID 的工具。 创建RAID 1: 使用mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sdb /dev/sdc 命令创建 RAID 1。 这里/dev/md0 是创建的 RAID 设备名,/dev/sdb ...

After that, you need to verify if the RAID devices' level is same as your configuration. [root@server2 Desktop]# mdadm -D /dev/md5 Next, you should create file system for raid devices. It is essential for mounting the RAID device. Run the following command for the same purpose. ...
The first step in creating an array is to prepare the hard drive for a RAID configuration. You need to open a terminal and run the command: sudo fdisk - 1 This will give you a list of disks that are connected to your computer. ...
Drive Operations in Progress 是否存在正在后台处理的硬盘操作。 MegaRAID xxx 高级特性的使能状态。 Manage MegaRAID Advanced Software Options 管理高级特性。 进入“Create Virtual Drive”界面。 在主界面中选择“Main Menu”并按“Enter”。 选择“Configuration Management”并按“Enter”。
These may be linear, striped, mirrored, or a more complex parity configuration. We should note that creating a RAID LVM Logical Volume uses Linux kernel RAID (mdraid). If we want the convenience of LVM, being able to expand Volume Groups and resize Logical Volumes, we can have it along ...
