-Subject: ANNOUNCE: mdadm 3.3 - A tools for managing md Soft RAID under Linux
-
-I am pleased to announce the availability of
- mdadm version 3.3
-
-It is available at the usual places:
- http://www.kernel.org/pub/linux/utils/raid/mdadm/
-and via git at
- git://github.com/neilbrown/mdadm
- git://neil.brown.name/mdadm
- http://git.neil.brown.name/git/mdadm
-
-This is a major new release so don't be too surprised if there are a
-few issues. If I hear about them they will be fixed in 3.3.1.
-git log reports nearly 500 changes since 3.2.6 so I won't list them
-all.
-
-Some highlights are:
-
-- Some array reshapes can proceed without needing backup file.
- This is done by changing the 'data_offset' so we never need to write
- any data back over where it was before. If there is no "head space"
- or "tail space" to allow data_offset to change, the old mechanism
- with a backup file can still be used.
-- RAID10 arrays can be reshaped to change the number of devices,
- change the chunk size, or change the layout between 'near'
- and 'offset'.
- This will always change data_offset, and will fail if there is no
- room for data_offset to be moved.
-- "--assemble --update=metadata" can convert a 0.90 array to a 1.0 array.
-- bad-block-logs are supported (but not heavily tested yet)
-- "--assemble --update=revert-reshape" can be used to undo a reshape
- that has just been started but isn't really wanted. This is very
- new and while it passes basic tests it cannot be guaranteed.
-- improved locking between --incremental and --assemble
-- uses systemd to run "mdmon" if systemd is configured to do that.
-- kernel names of md devices can be non-numeric. e.g. "md_home" rather than
- "md0". This will probably confuse lots of other tools, so you need to
- echo CREATE names=yes >> /etc/mdadm.conf
- or the feature will not be used. (you also need a reasonably new kernel).
-- "--stop" can be given a kernel name instead of a device name. i.e
- mdadm --stop md4
- will work even if /dev/md4 doesn't exist.
-- "--detail --export" has some information about the devices in the array
-- --dump and --restore can be used to backup and restore the metadata on an
- array.
-- Hot-replace is supported with
- mdadm /dev/mdX --replace /dev/foo
- and
- mdadm /dev/mdX --replace /dev/foo --with /dev/bar
-- Config file can be a directory in which case all "*.conf" files are
- read in lexical order.
- Default is to read /etc/mdadm.conf and then /etc/mdadm.conf.d
- Thus
- echo CREATE name=yes > /etc/mdadm.conf.d/names.conf
- will also enable the use of named md devices.
-
-- Lots of improvements to DDF support including adding support for
- RAID10 (thanks Martin Wilck).
-
-and lots of bugfixes and other little changes.

-
-The main changes are:
- - lots of work on "DDF" support. Hopefully it will be more stable
- now. Bug reports are always welcome.
- - improved interactions with 'systemd'. Where possible, background
- tasks are run from systemd (if it is present) rather then forking
- disassociationg from the session. This is important because udev
- doesn't really let you disassociate.
-
-though there are a number of other little bug fixes too.

-Subject: ANNOUNCE: mdadm 3.3.4 - A tool for managing md Soft RAID under Linux
-
-I am somewhat disappointed to have to announce the availability of
- mdadm version 3.3.4

-
-In mdadm-3.3 a change was made to how IMSM (Intel Matrix Storage
-Manager) metadata was handled. Previously an IMSM array would only
-be assembled if it was attached to an IMSM controller.
-
-In 3.3 this was relaxed as there are circumstances where the
-controller is not properly detected. Unfortunately this has negative
-consequences which have only just come to light.
-
-If you have an IMSM RAID1 configured and then disable RAID in the
-BIOS, the metadata will remain on the devices. If you then install
-some other OS on one device and then install Linux on the other, Linux
-might eventually start noticing the IMSM metadata (depending a bit on whether
-mdadm is included in the initramfs) and might start up the RAID1. This could
-copy one device over the other, thus trashing one of the installations.
-
-Not good.
-
-So with this release IMSM arrays will only be assembled if attached to
-an IMSM controller, or if "--force" is given to --assemble, or if the
-environment variable IMSM_NO_PLATFORM is set (used primarily for
-testing).
-
-I strongly recommend upgrading to 3.3.4 if you are using 3.3 or later.
