+Subject: ANNOUNCE: mdadm 2.6 - A tool for managing Soft RAID under Linux
+
+I am pleased to announce the availability of
+ mdadm version 2.6
+
+It is available at the usual places:
+ http://www.cse.unsw.edu.au/~neilb/source/mdadm/
+and
+ 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
+
+mdadm is a tool for creating, managing and monitoring
+device arrays using the "md" driver in Linux, also
+known as Software RAID arrays.
+
+Release 2.6 adds assorted fixes and improvements and a new major mode.
+"Incremental Assembly" via -I or --incremental can be used to
+assemble an array one device at a time. The idea is that you get
+udev to run "mdadm -Iq devicename" on each new block device that it
+finds. Anything that is part of an array gets included in an array as
+appropriate.
+Two special notes:
+ 1/ This is very new code and is probably buggy. It passes a few basic
+ tests, and helped me find some kernel bugs, but it is still fresh
+ and should not be considered 'stable'. Please test and provide
+ feedback.
+ 2/ There is a bug in the linux kernel that makes incremental assembly
+ not possible in general (you cannot safely remove a drive from an array
+ that has not yet been started. This is needed if an old device was
+ detected first). If mdadm detects a kernel which might have the
+ bug, it rejects --incremental requests.
+ The bug will hopefully be fixed in 2.6.20 and this mdadm release
+ contains patches for 2.6.18, 2.6.18.6 and 2.6.19. Apply the
+ appropriate patch to test --incremental.
+
+Changelog Entries:
+ - Fixed UUID printing in "--detail --brief" for version1 metadata.
+ - --update=resync did exactly the wrong thing for version1 metadata.
+ It caused a resync to not happen, rather than to happen.
+ - Allow --assemble --force to mark a raid6 clean when it has two
+ missing devices (which is needed else if won't assemble.
+ Without this fix it would only assemble if one or zero
+ missing devices.
+ - Support --update=devicesize for cases where the underlying device
+ can change size.
+ - Default to --auto=yes so the array devices with 'standard' names
+ get created automatically, as this is almost always what is wanted.
+ - Give useful message if raid4/5/6 cannot be started because it is
+ not clean and is also degraded.
+ - Increase raid456 stripe cache size if needed to --grow the array.
+ The setting used unfortunately requires intimate knowledge of the
+ kernel, and it not reset when the reshape finishes.
+ - Change 'Device Size' to 'Used Dev Size' because it only shows how
+ much of each device is actually used, not how big they are.
+ - --wait or -W will wait for resync activity to finish on the given
+ devices.
+ - Fix some problems with --update=uuid and add a test.
+ - If two drives in a raid5 disappear at the same time, then "-Af"
+ will add them both in rather than just one and forcing the array
+ to 'clean'. This is slightly safer in some cases.
+ - Check device is large enough before hot-add: this improves quality
+ of error message.
+ - Don't hold md device open for so long in --monitor mode - map_dev
+ can be slow and interferes with trying to stop the array.
+ - Support --uuid= with --create to choose your own UUID.
+ - New major more "--incremental" for incremental assemble of arrays,
+ intended for use with udev.
+
+Development of mdadm is sponsored by
+ SUSE Labs, Novell Inc.
