-Subject: ANNOUNCE: mdadm 3.0 - A tool for managing Soft RAID under Linux
-
-I am pleased to (finally) announce the availability of
- mdadm version 3.0
-
-It is available at the usual places:
- countrycode=xx.
- http://www.${countrycode}kernel.org/pub/linux/utils/raid/mdadm/
-and via git at
- git://neil.brown.name/mdadm
- http://neil.brown.name/git?p=mdadm
-
-
-This is a major new version and as such should be treated with some
-caution. However it has seen substantial testing and is considerred
-to be ready for wide use.
-
-
-The significant change which justifies the new major version number is
-that mdadm can now handle metadata updates entirely in userspace.
-This allows mdadm to support metadata formats that the kernel knows
-nothing about.
-
-Currently two such metadata formats are supported:
- - DDF - The SNIA standard format
- - Intel Matrix - The metadata used by recent Intel ICH controlers.
-
-Also the approach to device names has changed significantly.
-
-If udev is installed on the system, mdadm will not create any devices
-in /dev. Rather it allows udev to manage those devices. For this to work
-as expected, the included udev rules file should be installed.
-
-If udev is not installed, mdadm will still create devices and symlinks
-as required, and will also remove them when the array is stopped.
-
-mdadm now requires all devices which do not have a standard name (mdX
-or md_dX) to live in the directory /dev/md/. Names in this directory
-will always be created as symlinks back to the standard name in /dev.
-
-The man pages contain some information about the new externally managed
-metadata. However see below for a more condensed overview.
-
-Externally managed metadata introduces the concept of a 'container'.
-A container is a collection of (normally) physical devices which have
-a common set of metadata. A container is assembled as an md array, but
-is left 'inactive'.
-
-A container can contain one or more data arrays. These are composed from
-slices (partitions?) of various devices in the container.
-
-For example, a 5 devices DDF set can container a RAID1 using the first
-half of two devices, a RAID0 using the first half of the remain 3 devices,
-and a RAID5 over thte second half of all 5 devices.
-
-A container can be created with
-
- mdadm --create /dev/md0 -e ddf -n5 /dev/sd[abcde]
-
-or "-e imsm" to use the Intel Matrix Storage Manager.
-
-An array can be created within a container either by giving the
-container name and the only member:
-
- mdadm -C /dev/md1 --level raid1 -n 2 /dev/md0
-
-or by listing the component devices
-
- mdadm -C /dev/md2 --level raid0 -n 3 /dev/sd[cde]
-
-To assemble a container, it is easiest just to pass each device in turn to
-mdadm -I
-
- for i in /dev/sd[abcde]
- do mdadm -I $i
- done
-
-This will assemble the container and the components.
-
-Alternately the container can be assembled explicitly
-
- mdadm -A /dev/md0 /dev/sd[abcde]
-
-Then the components can all be assembled with
-
- mdadm -I /dev/md0
-
-For each container, mdadm will start a program called "mdmon" which will
-monitor the array and effect any metadata updates needed. The array is
-initially assembled readonly. It is up to "mdmon" to mark the metadata
-as 'dirty' and which the array to 'read-write'.
-
-The version 0.90 and 1.x metadata formats supported by previous
-versions for mdadm are still supported and the kernel still performs
-the same updates it use to. The new 'mdmon' approach is only used for
-newly introduced metadata types.

-I am pleased to announce the availability of
- mdadm version 3.0.1
-
-It is available at the usual places:
- countrycode=xx.

-
-
-This contains only minor bug fixes over 3.0. If you are using
-3.0, you could consider upgrading.
-
-The brief change log is:
- - Fix various segfaults
- - Fixed for --examine with containers
- - Lots of other little fixes.

-This contains a collection of bug fixes and minor enhancements over
-3.0.1.
-
-The brief change log is:
- - Improvements for creating arrays giving just a name, like 'foo',
- rather than the full '/dev/md/foo'.
- - Improvements for assembling member arrays of containers.
- - Improvements to test suite
- - Add option to change increment for RebuildNN messages reported
- by "mdadm --monitor"
- - Improvements to mdmon 'hand-over' from initrd to final root.
- - Handle merging of devices that have left an IMSM array and are
- being re-incorporated.
- - Add missing space in "--detail --brief" output.
