Dzero.txt1 dm-zero
4 Device-Mapper's "zero" target provides a block-device that always returns
5 zero'd data on reads and silently drops writes. This is similar behavior to
6 /dev/zero, but as a block-device instead of a character-device.
8 Dm-zero has no target-specific parameters.
10 One very interesting use of dm-zero is for creating "sparse" devices in
14 device. Reads to previously unwritten areas will return a zero'd buffer. When
19 To create a sparse device, start by creating a dm-zero device that's the
