utilities for the dm-zoned device mapper


The dm-zoned device mapper target provides random write access to zoned block devices (ZBC and ZAC compliant devices). It hides to the device user (a file system or an application doing raw block device accesses) the sequential write constraint of host-managed zoned block devices, allowing the use of applications and file systems that do not have native zoned block device support.

The dmzadm utility allows formating backend devices for use with the dm-zoned device mapper target driver. This utility will inspect the device verifying that it is a zoned block device and will prepare and write on-disk dm-zoned metadata according to the device capacity, zone size, etc.
