 A Redundant Array of Independent Disks or RAID device is a virtual device created from two or more real block devices. This functionality allows multiple devices (typically disk drives or partitions of a disk) to be combined into a single device to hold a single filesystem. Some RAID levels include redundancy, allowing the filesystem to survive some degree of device failure.
 
-The Oracle Linux kernel uses the Multiple Device (MD) driver to support Linux software RAID and enable you to organize disk drives into RAID devices and implement different RAID levels.

 ### Objectives
 
 In this tutorial, you will learn how to:
 
-- Create a RAID1 device with a spare
-- Recover a failed RAID1 device

 ### Prerequisites
 
-The tutorial uses the following system:
+- Minimum of a single Oracle Linux system
 
-- Any Oracle Linux 8 system with the following configurations:
-  - a non-root user with sudo permissions
-  - additional block volumes for use with Linux Software RAID
+- Each system should have Oracle Linux installed and configured with:
+    - A non-root user account with sudo access
+    - Access to the Internet
+    - Two or more block devices attached to the system

 Access Control Lists (ACLs) provide access control to directories and files. ACLs can set read, write, and execute permissions for the owner, group, and all other system users.
 
-An ACL consists of a set of rules that specify how a specific user or group can access ACL enabled files and directories. A regular ACL entry specifies access information for a single file or directory. A default ACL entry is set on directories only, and specifies the default access information for any file within the directory that does not have an access ACL.

A default ACL entry is set on directories only and specifies the default access information for any file within the directory that does not have an access ACL.
 
-When setting a default ACL on a directory, its subdirectories inherit the same rights automatically. ACLs can be used with the `btrfs`, `ext3`, `ext4`, `OCFS2`, and `XFS` file systems, as well as mounted NFS file systems.
