Device mapper driver

Device mapper modular Linux kernel driver framework for constructing new block devices and mapping them to existing block devices managed through API (IOCTL interface) libdevmapper, dmsetup command utility DM knows nothing about LVM (logical volumes, volume groups) managed by userspace tools (LVM2, EVMS, )File Size: KB.  · In the image above, 'Microsoft Sound Mapper - Output' appears when the Windows 'MME' Audio Host is selected. This 'Mapper' device is not a separate playback device, but is the device that is currently chosen as the default system playback device in the Windows Control Panel. You may refer to the steps from the article below. Device Mapper is developed based on the kernel framework and supports many advanced volume management technologies on Linux. Docker Device Mapper storage driver leverages the thin provisioning and snapshot capabilities of this framework to manage images and containers.

You may refer to the steps from the article below. Device Mapper is a kernel-based framework that underpins many advanced volume management technologies on Linux. Docker’s devicemapper storage driver leverages the thin provisioning and snapshotting capabilities of this framework for image and container management.

The device mapper is a framework provided by the Linux kernel for mapping physical block devices onto higher-level virtual block devices. How to find the running docker storage device when docker is using the device-mapper storage driver and then check the size of it? Docker device mapper: can't find location where image is stored docker - driver "devicemapper" failed to remove root filesystem after process in.
