Linux : Linux Administration Advanced Disk Systems Practical

Learn to reduce existing logical volumes by shrinking the filesystem and the volume using manual steps, unmount, run fsck, resize the filesystem, and adjust LV size before remounting and verifying.

Learn to replace a physical drive in an lvm setup by adding a new pv, extending the volume group, shifting data with pvmove, and removing the old pv.

LVM snapshots freeze the region volume to enable backups without downtime, reserve 3–5% of the volume, and enable roll forward or roll back for testing OS updates.

Perform a file system check on an ext file system, back up with dump, and restore the image over ssh, including partitioning and formatting steps.

Learn how to set up disk storage with logical volume management by creating physical volumes, forming a volume group, and creating logical volumes across disks; explore extending, snapshots, and migrations.

Create physical volumes and three logical volumes in a volume group using B size or GB size with lvcreate, then format with a 64 file system and mount to folders.

Learn to set up thin provisioned Linux logical volumes by creating physical volumes, a volume group, and a thin pool, then create, mount, and test logical volumes.
