How to Use Linux Server LVM for Flexible Storage
from Linux Server Admin with Fexingo: Sysadmin, Bash, and Server Engineering Hosted by Fexingo
In this episode of Linux Server Admin with Fexingo, Lucas and Luna dive into Logical Volume Management (LVM) — the Linux storage technology that lets you resize filesystems on the fly, take snapshots, and manage disk space without downtime. They explore a real-world scenario: a database server that runs out of disk space on a Friday afternoon. Instead of panicking, you can add a new physical disk, extend the volume group, and grow the logical volume while the system stays up. Lucas breaks down the core concepts — physical volumes, volume groups, and logical volumes — and walks through the essential commands like pvcreate, vgcreate, lvextend, and lvresize. He also discusses thin provisioning, a feature that lets you overcommit storage, and explains why LVM is a game-changer for server admins. Luna challenges Lucas on when NOT to use LVM — like for high-performance databases on raw devices — and they share practical tips for monitoring and snapshotting. Whether you're a sysadmin or just curious about Linux storage, this episode gives you a concrete tool to handle disk issues like a pro. #Linux #ServerAdmin #LVM #LogicalVolumeManagement #Sysadmin #Storage #Bash #ServerEngineering #Technology #OpenSource #DevOps #Infrastructure #DiskManagement #ThinProvisioning #Snapshots #FexingoBusiness #BusinessPodcast #LinuxPodcast Keep every episode free: buymeacoffee.com/fexingo
