Flash-EEPROM in a Router – a true MTD. A Memory Technology Device (MTD) is a type of device file in Linux for interacting with flash memory. The MTD subsystem was created to provide an abstraction layer between the hardware-specific device drivers and higher-level applications. Although character and block device files already existed, their ...
UBIFS (UBI File System, more fully Unsorted Block Image File System) is a flash file system for unmanaged flash memory devices. [1] UBIFS works on top of an UBI (unsorted block image) layer, [2] which is itself on top of a memory technology device (MTD) layer. [3] The file system is developed by Nokia engineers with help of the University of ...
A loadable kernel module (LKM) is an executable library that extends the capabilities of a running kernel, or so-called base kernel, of an operating system.LKMs are typically used to add support for new hardware (as device drivers) and/or filesystems, or for adding system calls.
The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices. It forms the foundation of the logical volume manager (LVM), software RAIDs and dm-crypt disk encryption, and offers additional features such as file system snapshots .
A flash file system is a file system designed for storing files on flash memory–based storage devices. While flash file systems are closely related to file systems in general, they are optimized for the nature and characteristics of flash memory (such as to avoid write amplification ), and for use in particular operating systems .
udev (userspace /dev) is a device manager for the Linux kernel.As the successor of devfsd and hotplug, udev primarily manages device nodes in the /dev directory. At the same time, udev also handles all user space events raised when hardware devices are added into the system or removed from it, including firmware loading as required by certain devices.
Marks a path as failed when the path becomes faulty. Depending on the failback policy, it can reactivate the path. [5] Devmap-name: provides a meaningful device-name to udev for devmaps. [5] Kpartx: maps linear devmaps to device partitions to make multipath maps partitionable. [5] Multipath.conf: configuration file for the multipath daemon ...
The linux kernel implements multipath disk access via the software RAID stack known as the md (Multiple Devices) driver. The kernel portion of the md multipath driver only handles routing I/O requests to the proper device and handling failures on the active path.
