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 - -And please: don't use this in production - particularly not the ---grow functionality. - -NeilBrown 1st February 2011 - - diff --git a/ANNOUNCE-3.2.1 b/ANNOUNCE-3.2.1 deleted file mode 100644 index 0e7826c..0000000 --- a/ANNOUNCE-3.2.1 +++ /dev/null @@ -1,75 +0,0 @@ - - -I am pleased to announce the availability of - mdadm version 3.2.1 - -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 - -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. - -NeilBrown 28th March 2011 diff --git a/ANNOUNCE-3.2.2 b/ANNOUNCE-3.2.2 deleted file mode 100644 index b70d18b..0000000 --- a/ANNOUNCE-3.2.2 +++ /dev/null @@ -1,36 +0,0 @@ -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.
