-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.

-This is a bugfix release over 3.1, which was withdrawn due to serious
-bugs. So it might be best to ignore 3.1 and say that this is a significant
-feature release over 3.0.x
-
-Significant changes are:
- - RAID level conversion between RAID1, RAID5, and RAID6 are
- possible were the kernel supports it (2.6.32 at least)
- - online chunksize and layout changing for RAID5 and RAID6
- where the kernel supports it.
- - reduce the number of devices in a RAID4/5/6 array.
-
- - The default metadata is not v1.1. This metadata is stored at the
- start of the device so is safer in many ways but could interfere with
- boot loaded. The old default (0.90) is still available and fully
- supported.
-
- - The default chunksize is now 512K rather than 64K. This seems more
- appropriate for modern devices.
-
- - The default bitmap chunksize for internal bitmaps is now at least
- 64Meg as fine grained bitmaps tend to impact performance more for
- little extra gain.
-
-This release is believed to be stable and you should feel free to
-upgrade to 3.1.1.

-Significant changes are:
- - The default metadata has change again (sorry about that).
- It is now v1.2 and will hopefully stay that way. It turned
- out there with boot-block issues with v1.1 which make it
- unsuitable for a default, though in many cases it is still
- suitable to use.
- - Stopping a container is not permitted when members are still
- active
- - Add 'homehost' to the valid words for the "AUTO" config file
- line. When followed by "-all", this causes mdadm to
- auto-assemble any array belonging to this host, but not
- auto-assemble anything else.
- - Fix some bugs with "--grow --chunksize=" for changing chunksize.
- - VAR_RUN can be easily changed at compile time just like ALT_RUN.
- This gives distros more flexability in how to manage the
- pid and sock files that mdmon needs.
- - Various mdmon fixes
- - Alway make bitmap 4K-aligned if at all possible.
- - If mdadm.conf lists arrays which have inter-dependencies,
- the previously had to be listed in the "right" order. Now
- any order should work.
- - Fix --force assembly of v1.x arrays which are in the process
- of recovering.

-Subject: ANNOUNCE: mdadm 3.2 - A tool for managing Soft RAID under Linux (DEVEL ONLY)
-
-I am pleased to announce the availability of
- mdadm version 3.2
-
-It is available at the usual places:
- countrycode=xx.
- http://www.${countrycode}kernel.org/pub/linux/utils/raid/mdadm/
-and via git at

- http://neil.brown.name/git?p=mdadm
-
-This is a "Developers only" release. Please don't consider using it
-or making it available to others without reading the following.
-
-
-By far the most significant change in this release related to the
-management of reshaping arrays. This code has been substantially
-re-written so that it can work with 'externally managed metadata' -
-Intel's IMSM in particular. We now support level migration and
-OnLine Capacity Expansion on these arrays.
-
-However, while the code largely works it has not been tested
-exhaustively so there are likely to be problems. As the reshape code
-for native metadata arrays was changed as part of this rewrite these
-problems could also result in regressions for reshape of native
-metadata.
-
-It is partly to encourage greater testing that this release is being
-made. Any reports of problem - particular reproducible recipes for
-triggering the problems - will be gratefully received.
-
-It is hopped that a "3.2.1" release will be available in early March
-which will be a bugfix release over this and can be considered
-suitable for general use.
-
-Other changes of note:
-
- - Policy framework.
- Various policy statements can be made in the mdadm.conf to guide
- the behaviour of mdadm, particular with regards to how new devices
- are treated by "mdadm -I".
- Depending on the 'action' associated with a device (identified by
- its 'path') such need devices can be automatically re-added to and
- existing array that they previously fell out off, or automatically
- added as a spare if they appear to contain no data.
-
- - mdadm now has a limited understanding of partition tables. This
- allows the policy framework to make decisions about partitioned
- devices as well.
-
- - --incremental --remove can be told what --path the device was on,
- and this info will be recorded so that another device appearing at
- the same physical location can be preferentially added to the same
- array (provides the spare-same-slot action policy applied to the
- path).
-
- - A new flags "--invalid-backup" flag is available in --assemble
- mode. This can be used to re-assemble an array which was stopping
- in the middle of a reshape, and for which the 'backup file' is no
- longer available or is corrupted. The array may have some
- corruption in it at the point where reshape was up to, but at least
- the rest of the array will become available.
-
-
- - Various internal restructuring - more is needed.
-
-
-Any feed back and bug reports are always welcomed at:
- linux-raid@vger.kernel.org

- http://neil.brown.name/git/mdadm
-
-Many of the changes in this release are of internal interest only,
-restructuring and refactoring code and so forth.
-
-Most of the bugs found and fixed during development for 3.2.1 have been
-back-ported for the recently-release 3.1.5 so this release primarily
-provides a few new features over 3.1.5.
-
-They include:
- - policy framework
- Policy can be expressed for moving spare devices between arrays, and
- for how to handle hot-plugged devices. This policy can be different
- for devices plugged in to different controllers etc.
- This, for example, allows a configuration where when a device is plugged
- in it is immediately included in an md array as a hot spare and
- possibly starts recovery immediately if an array is degraded.
-
- - some understanding of mbr and gpt paritition tables
- This is primarly to support the new hot-plug support. If a
- device is plugged in and policy suggests it should have a partition table,
- the partition table will be copied from a suitably similar device, and
- then the partitions will hot-plug and can then be added to md arrays.
-
- - "--incremental --remove" can remember where a device was removed from
- so if a device gets plugged back in the same place, special policy applies
- to it, allowing it to be included in an array even if a general hotplug
- will not be included.
-
- - enhanced reshape options, including growing a RAID0 by converting to RAID4,
- restriping, and converting back. Also convertions between RAID0 and
- RAID10 and between RAID1 and RAID10 are possible (with a suitably recent
- kernel).
-
- - spare migration for IMSM arrays.
- Spare migration can now work across 'containers' using non-native metadata
- and specifically Intel's IMSM arrays support spare migrations.
-
- - OLCE and level migration for Intel IMSM arrays.
- OnLine Capacity Expansion and level migration (e.g. RAID0 -> RAID5) is
- supported for Intel Matrix Storage Manager arrays.
- This support is currently 'experimental' for technical reasons. It can
- be enabled with "export MDADM_EXPERIMENTAL=1"
-
- - avoid including wayward devices
- If you split a RAID1, mount the two halves as two separate degraded RAID1s,
- and then later bring the two back together, it is possible that the md
- metadata won't properly show that one must over-ride the other.
- mdadm now does extra checking to detect this possibilty and avoid
- potentially corrupting data.
-
- - remove any possible confusion between similar options.
- e.g. --brief and --bitmap were mapped to 'b' and mdadm wouldn't
- notice if one was used where the other was expected.
-
- - allow K,M,G suffixes on chunk sizes
-
-
-While mdadm-3.2.1 is considered to be reasonably stable, you should
-only use it if you want to try out the new features, or if you
-generally like to be on the bleeding edge. If the new features are not
-important to you, then 3.1.5 is probably the appropriate version to be using
-until 3.2.2 comes out.

-Subject: ANNOUNCE: mdadm 3.2.2 - A tool for managing Soft RAID under Linux
-
-I am pleased to announce the availability of
- mdadm version 3.2.2
-
-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/mdadm
-
-This release is largely a stablising release for the 3.2 series.
-Many of the changes just fix bugs introduces in 3.2 or 3.2.1.
-
-There are some new features. They are:
- - reshaping IMSM (Intel metadata) arrays is no longer 'experimental',
- it should work properly and be largely compatible with IMSM drivers in
- other platforms.
- - --assume-clean can be used with --grow --size to avoid resyncing the
- new part of the array. This is only support with very new kernels.
- - RAID0 arrays can have chunksize which is not a power of 2. This has been
- supported in the kernel for a while but is only now supprted by
- mdadm.
-
- - A new tool 'raid6check' is available which can check a RAID6 array,
- or part of it, and report which device is most inconsistent with the
- others if any stripe is inconsistent. This is still under development
- and does not have a man page yet. If anyone tries it out and has any
- questions or experience to report, they would be most welcome on
- linux-raid@vger.kernel.org.
-
-Future releases in the 3.2 series will only be made if bugfixes are needed.
-The next release to add features is expected to be 3.3.

-This release primarily fixes a serious regression in 3.2.4.
-This regression does *not* cause any risk to data. It simply
-means that adding a device with "--add" would sometime fail
-when it should not.
-
-The fix also includes a couple of minor fixes such as making
-the "--layout=preserve" option to "--grow" work again.
-
-A reminder that the default location for runtime files is now
-"/run/mdadm". If you compile this for a distro that does not
-have "/run", you will need to compile with an alternate setting for

-
-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.

-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
-
-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.git
-
-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.

-DDF:
- Three new metadata types:
- ddf - used only to create a container.
- ddf-bvd - used to create an array in a container
- ddf-svd - used to create a secondary array from bvds.
-
- Usage:
- mdadm -C /dev/ddf1 /dev/sd[abcdef]
- mdadm -C /dev/md1 -e ddf /dev/sd[a-f]
- mdadm -C /dev/md1 -l container /dev/sd[a-f]
-
- Each of these create a new ddf container using all those
- devices. The name 'ddf*' signals that ddf metadata should be used.
- '-e ddf' only supports one level - 'container'. 'container' is only
- supported by ddf.
-
- mdadm -C /dev/md1 -l0 -n4 /dev/ddf1 # or maybe not ???
- mdadm -C /dev/md1 -l1 -n2 /dev/sda /dev/sdb
- If exactly one device is given, and it is a container, we select
- devices from that container.
- If devices are given that are already in use, they must be in use by
- a container, and the array is created in the container.
- If devices given are bvds, we slip under the hood to make
- the svd arrays.
-
- mdadm -A /dev/ddf ......
- base drives make a container. Anything in that container is started
- auto-read-only.
- if /dev/ddf is already assembled, we assemble bvds and svds inside it.

- Want an incremental assembly mode to work nicely with udev.
- Core usage would be something like
- mdadm --incr-assemble /dev/newdevice
- This would
- - examine the device to determine uuid etc.
- - look for a match in /etc/mdadm.conf, abort if not found
- - find that device and collect current contents
- - perform an 'assemble' analysis to make sure we have the best set of devices.
- - remove or add devices as appropriate
- - possibly start the array if it was complete
-
- Other usages could involve
- - specify which array to auto-add to.
- This requires an existing array for uuid matching... is there any point?

-* Maybe make "--help" fit in 80x24 and have a --long-help with more info. DONE
-
-
-* maybe "missing" instead of <bold>missing</> in doco DONE
-* possibly wait for resync to start, or even finish while assembling.- NO
-
-* -Db should have a devices= entry if possible. - DONE
-* when assembling multipath arrays, ignore any error indicators. - DONE
-* rationalise --monitor usage:
- mdadm --monitor
- doesn't do as expected. DONE
-
-* --assemble could have a --update option. - DONE
- following word can be:
- sparc2.2
- super-minor

-Assembling md arrays at boot time.
----------------------------------
-December 2005
-
-These notes apply to 2.6 kernels only and, in some cases,
-to 2.6.15 or later.
-
-Md arrays can be assembled at boot time using the 'autodetect' functionality
-which is triggered by storing components of an array in partitions of type
-'fd' - Linux Raid Autodetect.
-They can also be assembled by specifying the component devices in a
-kernel parameter such as
- md=0,/dev/sda,/dev/sdb
-In this case, /dev/md0 will be assembled (because of the 0) from the listed
-devices.
-
-These mechanisms, while useful, do not provide complete functionality
-and are unlikely to be extended. The preferred way to assemble md
-arrays at boot time is using 'mdadm'. To assemble an array which
-contains the root filesystem, mdadm needs to be run before that
-filesystem is mounted, and so needs to be run from an initial-ram-fs.
-It is how this can work that is the primary focus of this document.
-
-It should be noted up front that only the array containing the root
-filesystem should be assembled from the initramfs. Any other arrays
-should be assembled under the control of files on the main filesystem
-as this enhanced flexibility and maintainability.
-
-A minimal initramfs for assembling md arrays can be created using 3
-files and one directory. These are:
-
-/bin Directory
-/bin/mdadm statically linked mdadm binary
-/bin/busybox statically linked busybox binary
-/bin/sh hard link to /bin/busybox
-/init a shell script which call mdadm appropriately.
-
-An example init script is:
-
-==============================================
-#!/bin/sh
-
-echo 'Auto-assembling boot md array'
-mkdir /proc
-mount -t proc proc /proc
-if [ -n "$rootuuid" ]
-then arg=--uuid=$rootuuid
-elif [ -n "$mdminor" ]
-then arg=--super-minor=$mdminor
-else arg=--super-minor=0
-fi
-echo "Using $arg"
-mdadm -Acpartitions $arg --auto=part /dev/mda
-cd /
-mount /dev/mda1 /root || mount /dev/mda /root
-umount /proc
-cd /root
-exec chroot . /sbin/init < /dev/console > /dev/console 2>&1
-=============================================
-
-This could certainly be extended, or merged into a larger init script.
-Though tested and in production use, it is not presented here as
-"The Right Way" to do it, but as a useful example.
-Some key points are:
-
- /proc needs to be mounted so that /proc/partitions can be accessed
- by mdadm, and so that /proc/filesystems can be accessed by mount.
-
- The uuid of the array can be passed in as a kernel parameter
- (rootuuid). As the kernel doesn't use this value, it is made available
- in the environment for /init
-
- If no uuid is given, we default to md0, (--super-minor=0) which is a
- commonly used to store the root filesystem. This may not work in
- all situations.
-
- We assemble the array as a partitionable array (/dev/mda) even if we
- end up using the whole array. There is no cost in using the partitionable
- interface, and in this context it is simpler.
-
- We try mounting both /dev/mda1 and /dev/mda as they are the most like
- part of the array to contain the root filesystem.
-
- The --auto flag is given to mdadm so that it will create /dev/md*
- files automatically. This is needed as /dev will not contain
- and md files, and udev will not create them (as udev only created device
- files after the device exists, and mdadm need the device file to create
- the device). Note that the created md files may not exist in /dev
- of the mounted root filesystem. This needs to be deal with separately
- from mdadm - possibly using udev.
-
- We do not need to create device files for the components which will
- be assembled into /dev/mda. mdadm finds the major/minor numbers from
- /proc/partitions and creates a temporary /dev file if one doesn't already
- exist.
-
-The script "mkinitramfs" which is included with the mdadm distribution
-can be used to create a minimal initramfs. It creates a file called
-'init.cpio.gz' which can be specified as an 'initrd' to lilo or grub
-(or whatever boot loader is being used).
-
-
-
-
-Resume from an md array
------------------------
-
-If you want to make use of the suspend-to-disk/resume functionality in Linux,
-and want to have swap on an md array, you will need to assemble the array
-before resume is possible.
-However, because the array is active in the resumed image, you do not want
-anything written to any drives during the resume process, such as superblock
-updates or array resync.
-
-This can be achieved in 2.6.15-rc1 and later kernels using the
-'start_readonly' module parameter.
-Simply include the command
- echo 1 > /sys/module/md_mod/parameters/start_ro
-before assembling the array with 'mdadm'.
-You can then echo
- 9:0
-or whatever is appropriate to /sys/power/resume to trigger the resume.
