Device Mapper storage driver¶
MCR hosts that run the
devicemapper storage driver use the
configuration mode by default. This mode uses sparse files to build
the thin pool used by image and container snapshots and is designed to work
without any additional configuration.
Mirantis recommends that you use
direct-lvm mode in production
environments in lieu of
direct-lvm mode is more
efficient in its use of system resources than
loop-lvm mode, and you can
scale it as necessary.
For information on how to configure
direct-lvm mode, refer to the Docker
documentation, Use the Device Mapper storage driver.
