LVM requires physical volumes to be initialized before use. Reducing volumes requires careful handling to avoid data loss. Some operations require the logical volume to be unmounted.

LVM2 is the second major version of the Linux Logical Volume Manager, providing enterprise-grade storage management capabilities.
