LVM mirroring

LVM (Logical Volume Management) mirroring involves creating an exact copy of your data on two separate storage devices within a logical volume. This setup ensures that if one device fails, the data remains accessible from the other, improving fault tolerance. Think of it as having a real-time backup maintained automatically; changes made to the primary data are instantly reflected on the mirror. This way, your data stays protected without manual copying, providing both redundancy and reliability in managing storage resources.
