(Needed when + 1.x array was created with older mdadm). + - When adding a drive that was a little too small, we did not get + the correct error message. + - Make sure that if --assemble find an array in the critical region + of a reshape, and cannot find the critical data to restart the + reshape, it gives an error message. + - Fix segfault with '--detail --export' and non-persistent + superblocks. + - Various manpage updates. + - Improved 'raid4' support (--assemble, --monitor) + - Option parsing fixes w.r.t -a + - Interpret "--assemble --metadata=1" to allow any version 1.x + metadata, and be more specific in the "metadata=" message printed + with --examine --brief + - Fix spare migration in --monitor. + +Changes Prior to 2.6.2 release + - --fail detached and --remove faulty can be used to fail and + remove devices that are no longer physically present. + - --export option for --detail or present information in a format + that can be processed by udev. + - fix internal bitmap allocation problems with v1.1, v1.2 metadata. + - --help now goes to stdout so you can direct it to a pager. + - Various manpage updates. + - Make "--grow --add" for linear arrays really work. + - --auto-detect to trigger in-kernel autodetect. + - Make return code for "--detail --test" more reliable. Missing + devices as well as failed devices cause an error. + +Changes Prior to 2.6.1 release + - --monitor was producing some meaningless warnings due to a bug. + - Fix some compiler warnings. + - Fully support --grow for raid6. If a reshape crashed during the + critical period, mdadm wouldn't restore the Q information + properly. + - Update documentation for --grow. + +Changes Prior to 2.6 release + - 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. + +Changes Prior to 2.5.6 release + - Fix bug which meant "bitmap=xxx" in mdadm.conf was not handled + properly. + - Documentation updates. + - Fix bug that caused infinite loop when doing auto-assembly, + in certain cases where arrays couldn't be assembled. + +Changes Prior to 2.5.5 release + - Don't #include linux/blkpg.h as that isn't safe. Just + include the content literally. + - Reduce maximum bitmap usage when working with bitmap files, + so that a only single-page allocations are made, even on + 64bit hosts with 4K pages. + - Close stray fd in mdassemble so that it can assemble stacked + devices + - If mdassemble finds an array already assembled, it marks it + read-write. + - Remove error in md_open if array is already active. This isn't + needed and gets in the ways if an array was created e.g. in + initramfs, but device doesn't yet exist in /dev. + - When --assemble --scan is run, if all arrays that could be found + have already been started, don't report an error. + - Fix a couple of bugs related to raid10 and the new 'offset' layout. + - Improve error message when a wrong '--update' option is given. + +Changes Prior to 2.5.4 release + - When creating devices in /dev/md/ create matching symlinks + from /dev. e.g. /dev/md0 -> /dev/md/0. + Allow this to be disabled in mdadm.conf or on command line. + - Fix some endian-ness issues with version-1 superblocks (affects + bigendian only). + - Fix endian problem with 'bitmap' metadata + - Allow a number (of partitions) after the 'yes' option to --auto= + This is particularly useful in the 'create' line in mdadm.conf. + - Remove partitions from any whole device that is made part of + an md array. This is a work-around for annoying messages + when the first block on some drive accidentally looks like a + partition table. + Changes Prior to 2.5.3 release - Document v0.91 superblocks in md.4 + - Make GPL explicit in man pages. + - Fix recent breakage of starting degraded arrays. + - Tidyup automatic name choice for v-1 arrays: + /dev/md_d0 now becomes '0', not '_d0'. Changes Prior to 2.5.2 release - Fix problem with compiling with gcc-2 compilers
