Peter Anvin + - 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.

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.
