Lesson 4 of 12 · Volumes and file systems
Advanced LVM: thin provisioning, thin snapshots, SSD cache and pvmove migration
Objective
Go beyond the "PV → VG → LV" covered in the Red Hat, Debian and Ubuntu courses: overcommit space with a thin pool without ever letting it overflow, take snapshots that cost almost nothing, speed up a slow volume with an SSD cache, move data to a new storage array without downtime, and repair LVM metadata.
