Linux RAID & LVM Management

Install VirtualBox, download CentOS 7.4 minimal image and PuTTY, create CentOS and Windows 10 VMs with bridged and host-only networks, enable SSH on CentOS and disable firewalls for remote access.

Execute a practical Linux environment setup by configuring storage, network settings, and domain details. Adjust firewall rules and verify system readiness through installation steps on Red Hat and Arch environments.

Install Windows 10 in a virtual machine, install drivers, configure network connectivity, and adjust firewall settings, preparing you for the next practical lecture.

Set up and verify network connectivity between Windows and Linux machines by configuring the VM network settings, enabling remote access, and sharing a physical adapter for internet access.

Configure a linux NFS server and a Windows 10 NFS client to share a project directory. Install nfs-utils, create the /bgp_data share, and verify access from the client.

Explore the basics of RAID, including hardware and software RAID, and how it delivers performance, fault tolerance, backup, and integrated capacity.

Explore raid 0 by striping data across multiple drives for fast read and write access at low cost, noting no redundancy means data is lost on any drive failure.

Configure a Linux RAID 0 array by creating the device, formatting, and mounting it to a shared folder, then make it permanent and integrate with NFS.

Configure raid 5 in a linux server, create a raid 5 device, access it via NFS, permanently mount it, add disks, and designate a faulty drive.

Learn to set up Samba on a Linux server and configure a Samba client on Windows 10, including installing Samba, editing smb.conf, and mounting shared data.

Create physical volumes from /dev/sdb, /dev/sdc, and /dev/sdd using pvcreate, verify the setup with two commands, then create logical volumes and partitions and install a file system under /data.

Shrink an LVM partition by stopping the samba services, unmounting the volume, running e2fsck, resizing the logical volume to about 33 GB, remounting, and verifying the new data space.

Learn to create a 40 GB LVM logical volume, format with ext4, mount it, and extend the volume by 10 GB, resizing the filesystem to access the data.

In the Linux RAID & LVM Management course, learn how to remove an LVM partition by stopping SMB and NMB services and unmounting the volume at /dev/mylvg/new_lvm_part.

Review key concepts in the LVM section and clarify differences from the book to consolidate knowledge in Linux RAID and LVM management.
