lvm2

LVM2 is a Linux-based logical volume manager that allows for the creation of logical volumes on one or more physical hard drives.

LVM2 (Logical Volume Manager 2) is a tool used in Linux-based operating systems to manage and organize storage devices, including hard disks, SSDs, and other storage media, into logical volumes. LVM2 provides a layer of abstraction between physical storage devices and the file systems that use them, allowing for more flexibility and scalability in managing storage resources. With LVM2, multiple physical disks can be combined into a single logical volume, which can then be divided into smaller volumes or resized as needed. LVM2 also allows for snapshots and mirroring of volumes for backup and redundancy purposes.

dmeventd

The Linux Kernel Device Mapper is the LVM (Linux Logical Volume Management) Team’s implementation of a minimalistic kernel-space driver that handles volume management, while keeping knowledge of the underlying device layout in user-space. This makes it useful for not only LVM, but software raid, and other drivers that create “virtual” block devices.

This package contains a daemon to monitor events of devmapper devices.
