Changes Prior to this release
+ - Don't use 'lstat' to check for blockdevices, use stat.
+ - Document --size=max option for --grow
+ - Document SparesMissing event and DeviceDisappeared/WrongLevel
+ - --stop --scan repeatly cycles until no more progress can be made
+ so that stack devices are stopped properly
+ - Minor type rationalisation for ident->uuid - now always 'int[]'
+ - Fix type in online help for --grow (was -F, now -G)
+ - Allow --auto command line option to set default auto=
+ value when running "--assemble --scan". Previously
+ --auto was ignored if --scan was given
+ - Fix a few type casts
+ - Fix parsing of /dev/md/N in is_standard
+
+Changes Prior to 1.11.0 release
+ - Fix embarassing bug which causes --add to always fail.
+
+Changes Prior to 1.10.0 release
+ - Fix bug with --config=partitions
+ - Open sub-devices with O_EXCL to detect if already in use
+ - Make sure superblock updates are flushed directly to disk.
+
+Changes Prior to 2.0-deve-1 release
+ - Support for version-1 superblock. See --metadata option.
+ - Support for bitmap based intent logging.
+ - Minor fixes.
+
+Changes Prior to 1.9.0 release
+ - Fix rpm build problem (stray %)
+ - Minor manpage updates
+ - Change "dirty" status to "active" as it was confusing people.
+ - --assemble --auto recognises 'standard' name and insists on using
+ the appropriate major/minor number for them.
+ - Remove underscore from partition names, so partitions of
+ "foo" are "foo1", "foo2" etc (unchanged) and partitions of
+ "f00" are "f00p1", "f00p2" etc rather than "f00_p1"...
+ - Use "major", "minor", "makedev" macros instead of
+ "MAJOR", "MINOR", "MKDEV" so that large device numbers work
+ on 2.6 (providing you have glibc 2.3.3 or later).
+ - Add some missing closes of open file descriptors.
+ - Reread /proc/partition for every array assembled when using
+ it to find devices, rather than only once.
+ - Make "mdadm -Ss" stop stacked devices properly, by reversing the
+ order in which arrays are stopped.
+ - Improve some error messages.
+ - Allow device name to appear before first option, so e.g.
+ mdadm /dev/md0 -A /dev/sd[ab]
+ works.
+ - Assume '-Q' if just a device is given, rather than being silent.
+ - Change "dirty" status to "active" as it was confusing people.
+
+Changes Prior to 1.8.0 release
+ - Makefile cleanup from Luca Berra <bluca@comedia.it>
+ - --pid-file (-i) to set a pid file to use with --monitor --daemonise
+ - Fix typo in mdadm man page
+ - Fix coredump when "-s" used with no config file present.
+ - Support new "faulty" personality which can inject synthetic
+ faults. (Not in kernel.org yet at 1Nov2004)
+ - Support raid0/linear on devices > 2 Terabytes
+ - Make sure raid6 resyncs when created with one missing device
+
+Changes Prior to 1.7.0 release
+ - Support "--grow --add" to add a device to a linear array, if the
+ kernel supports it. Not documented yet.
+ - Restore support for uclibc which was broken recently.
+ - Several improvements to the output of --detail, including
+ reporting "resyncing" or "recovering" in the state.
+ - Close filedescriptor at end of --detail (exit would have closed it
+ anyway, so this isn't abig deal).
+ - Report "Sync checkpoint" in --examine output if appropriate.
+ - Add --update=resync for --assemble mode to for a resync when the
+ array is assembled.
+ - Add support for "raid10", which is under development in 2.6.
+ Not documented yet.
+ - --monitor now reads spare-group and spares info from config file
+ even when names of arrays to scan are given on the command line
+
+Changes Prior to 1.6.0 release
+ - Device name given in -Eb is determined by examining /dev rather
+ than assuming /dev/md%d
+ - Fix bug in --monitor where an array could be held open an so
+ could not be stopped without killing mdadm.
+ - Add --grow mode. Currently only --size and --raid-disks can be
+ changed. Both require kernel support which, at the time of
+ writing, is not in a release kernel yet.
+ - Don't print out "errors" or "no-errors" in -D and -E, as the bit
+ is never set or used.
+ - Use md event notification in 2.6.??? to make --monitor mode
+ respond instantly to events.
+ - Add --auto= option and auto= configfile entry to tell mdadm to
+ create device files as needed. This is particularly useful
+ with partitioned arrays where the major device number can change.
+ - When generating --brief listing, if the standard name doesn't
+ exist, search /dev for one rather than using a temp name.
+ - Allow --build to build raid1 and multipath arrays.
+ - Add "--assume-clean" for Create and Build, particularly for raid1
+ Note: this is dangerous. Only use it if you are certain.
+ - Fix bug so that Rebuild status monitoring works again.
+ - Add "degraded" and "recovering" options to the "Status:"
+ entry for --detail
+
+Changes Prior to 1.5.0 release
+ - new commands "mdassemble" which is a stripped-down equivalent of
+ "mdadm -As", that can be compiled with dietlibc.
+ Thanks to Luca Berra <bluca@comedia.it>.
+ It can be using in an initramfs or initrd.
+ - Fix compiling error with BLKGETSIZE64 and some signed/unsigned
+ comparison warnings.
+ - Add Rebuild Status (% complete) to --detail output.
+ - Support "--monitor --test" which will generate a test alert
+ for each array once, to test notification paths.
+ - Generate RebuildFinished event when rebuild finishes.
+ - Support for raid6 as found in 2.6.2 - thanks to
+ H. Peter Anvin <hpa@zytor.com>
+ - Support partitioned md arrays with a different major number and
+ naming scheme (md_dX in /proc/mdstat, /dev/md/dXpY in /dev).
+
+Changes Prior to 1.4.0 release
+ - Document fact that creating a raid5 array really creates a
+ degraded array with a spare.
+ - Add "spares=" tag to config file and generate it wit --detail and
+ --examine
+ - Add "SparesMissing" event when --monitor first sees an array and
+ it doesn't have the enough spare devices.
+ - Add --update=summaries for --assemble to update summary
+ information in superblock, and correct other inconsistancies in
+ the superblock.
+ - Add --test option to --detail to set a meaningful exit status.
+
+Changes Prior to 1.3.0 release
+ - Make 'size' and unsigned long in Create to allow creation of
+ larger arrays.
+ - Explicitly flag spare devices as 'spare' in --detail and --examine
+ output. Previously they simply had no flags lists.
+ - Make MailCmd (for monitor) configurable in Makefile, and default
+ to "/usr/sbin/sendmail -t". Also split out the warning related
+ flags into CWFLAGS for easier build configurability.
+ - Minor bugfix in Manage code.
+ - --monitor now notices and reports degraded arrays at startup using
+ "DegradedArray" event, and also has a --oneshot option to only
+ report DegradedArrays, and then exit.
+ - Small man-page clarification w.r.t. raid levels and raid4 in
+ particular.
+ - Disallow creation of arrays with only one device as this is
+ probably a mistake. --force will override this check.
+ - Correct some misleading documentation in the "mdadm --create --help"
+ message.
+ - Ignore chunksize if raid1 or multipath.
+ - Explicit statement in man page that raid-disks cannot be changed
+ after array is created.
+ - Improve message when attempting to start an array with
+ insufficient devices. Instead of required the array to be full,
+ we only require it has as many active devices as last time.
+
+Changes Prior to 1.2.0 release
+ - Fix bug where --daemonise required an argument.
+ - In --assemble --verbose, print appropriate message if device is
+ not in devices= list
+ - Updated mdadm.conf.5 to reflect fact that device= takes wildcards
+ - Typos: componenet -> component
+ - Reduce size of "--help" message put excess into "--help-options"
+ - Fix bug introduced when MD_SB_DISKS dependancy removed, and which
+ caused spares not be assembled properly.
+ - Print appropriate message if --monitor --scan decides not to
+ monitor anything.
+Changes Prior to 1.1.0 release
+ - add --deamonise flag for --monitor - forks and prints pid to stdout
+ - Fix bug so we REALLY clear dirty flag with -Af
+ - -Db now prints a 'devices=' word for each array.
+ - "mdadm -A /dev/md0" will get info from configfile, even without scan
+ - When assembling multipath arrays, ignore devices which are flagged
+ as having errors.
+ - take --super-minor=dev to mean "use the minor number of the mddev
+ being assembled.
+ - take --config=none to mean "completely ignore config file"
+ - Make --monitor require --scan or a device list.
Changes Prior to 1.0.9 release
- Documentation updates including kernel parameters documented
in md.4
- Fix printing of Gibibytes - calc was wrong.
- Fix printing of Array Size in --detail when very big.
- --monitor no longer tries to work for raid0 or linear as these
- have nothing to be monitors.
+ have nothing to be monitored.
- The word 'partitions' on a DEVICE line will cause all partitions
listed in /proc/partitions to be considered
- If the config file is called 'partitions' then it will be treated
as though it contained exactly 'device partitions' so e.g.
mdadm -Ebsc partitions
- will fill all raid partitions easily.
+ will find all raid partitions easily.
- successfully assemble multipath devices by ignoring raid_disk
value from superblock (it is always the same).
- --assemble not tied to MD_SB_DISKS limit quite so much
the --help output, is not wholy correct. After I get --follow
working properly, I plan to revise the various documentation and/or
the code to make sure the two match.
