How to Use Linux Server LVM Cache for Faster 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 LVM cache — a feature that lets you accelerate slower spinning disks with fast NVMe or SSD storage without rebuilding your filesystem. They explain how LVM cache works, using a practical example of a mail server with a 10TB HDD array and a 512GB NVMe drive. Lucas walks through the key commands and concepts: cache pools, cache modes (writeback and writethrough), and how to monitor performance with lvs and lvdisplay. They discuss when LVM cache makes sense — like for mixed read-heavy workloads — and when it doesn't, touching on considerations like cache size and SSD endurance. By the end, you'll understand how to set up and manage LVM cache on your own servers, and you'll know the trade-offs between performance and complexity. If you're a sysadmin looking to squeeze more life out of your existing hardware, this episode gives you a concrete tool to do it. #LinuxServerAdmin #LVMcache #LVM #StoragePerformance #NVMe #SSD #Sysadmin #ServerEngineering #Bash #Technology #FexingoBusiness #BusinessPodcast #Linux #ServerTips #StorageManagement #DataCenter #DevOps #ITInfrastructure Keep every episode free: buymeacoffee.com/fexingo
