Changes Prior to release 3.1.4
Two fixes related to configs that aren't using udev:
- Don't remove md devices which 'standard' names on --stop
- Allow dev_open to work on read-only /dev
And fixed regressions:
- Allow --incremental to add spares to an array
- Accept --no-degraded as a deprecated option rather than
throwing an error
- Return correct success status when --incrmental assembling
a container which does not yet have enough devices.
- Don't link mdadm with pthreads, only mdmon needs it.
- Fix compiler warning due to bad use of snprintf
Changes Prior to release 3.1.3
- mapfile now lives in a fixed location which default to
/dev/.mdadm/map but can be changed at compile time. This
location is choses and most distros provide it during early
boot and preserve it through. As long a /dev exists and is
writable, /dev/.mdadm will be created.
Other files file communication with mdmon live here too.
This fixes a bug reported by Debian and Gentoo users where
udev would spin in early-boot.
- IMSM and DDF metadata will not be recognised on partitions
as they should only be used on whole-disks.
- Various overflows causes by 2G drives have been addressed.
- A subarray of an IMSM contain can now be killed with
--kill-subarray. Also subarrays can be renamed with
--update-subarray
- -If (or --incremental --fail) can be used from udev to
fail and remove from all arrays a device which has been
unplugged from the system. i.e. hot-unplug-support.
- "mdadm /dev/mdX --re-add missing" will look for any device
that looks like it should be a member of /dev/mdX but isn't
and will automatically --re-add it
- Now compile with -Wextra to get extra warnings.
- Lots of minor bug fixes, documentation improvements, etcc
Changes Prior to release 3.1.2
- The default metadata has change again (sorry about that).
It is now v1.2 and will hopefully stay that way. It turned
out there with boot-block issues with v1.1 which make it
unsuitable for a default, though in many cases it is still
suitable to use.
- Stopping a container is not permitted when members are still
active
- Add 'homehost' to the valid words for the "AUTO" config file
line. When followed by "-all", this causes mdadm to
auto-assemble any array belonging to this host, but not
auto-assemble anything else.
- Fix some bugs with "--grow --chunksize=" for changing chunksize.
- VAR_RUN can be easily changed at compile time just like ALT_RUN.
This gives distros more flexability in how to manage the
pid and sock files that mdmon needs.
- Various mdmon fixes
- Alway make bitmap 4K-aligned if at all possible.
- If mdadm.conf lists arrays which have inter-dependencies,
the previously had to be listed in the "right" order. Now
any order should work.
- Fix --force assembly of v1.x arrays which are in the process
of recovering.
- Add section on 'scrubbing' to 'md' man page.
- Various command-line-option parsing improvements.
- ... and lots of other bug fixes.
Changes Prior to release 3.1.1
- Multiple fixes for new --grow levels including fixes for
serious data corruption problems.
- Change default metadata to v1.1
- Change default chunk size to 512K
- Change default bitmap chunk size to 64Meg
- When --re-add is used, don't fall back to
--add if --re-add fails as this can destroy data.
Changes Prior to release 3.1
- Support --grow to change the layout of RAID4/5/6
- Support --grow to change the chunksize of raid 4/5/6
- Support --grow to change level from RAID1 -> RAID5 -> RAID6 and
back.
- Support --grow to reduce the number of devices in RAID4/5/6.
- Support restart of these grow options which assembling an array
which is partially grown.
- Assorted tests of this code, and of different RAID6 layouts.
Changes Prior to release 3.0.3
- Improvements for creating arrays giving just a name, like 'foo',
rather than the full '/dev/md/foo'.
- Improvements for assembling member arrays of containers.
- Improvements to test suite
- Add option to change increment for RebuildNN messages reported
by "mdadm --monitor"
- Improvements to mdmon 'hand-over' from initrd to final root.
- Handle merging of devices that have left an IMSM array and are
being re-incorporated.
- Add missing space in "--detail --brief" output.
Changes Prior to release 3.0.2
- Fix crash when hosthost is not set, as often happens in
early boot.
Changes Prior to release 3.0.1
- Fix various segfaults
- Fixed for --examine with containers
- Lots of other little fixes.
Changes Prior to release 3.0
- Support for externally managed metadata, specifically DDF and IMSM.
- Depend on udev to create entries in /dev, rather than creating them
ourselves.
- remove --auto-update-home-hosts
- new config file line "auto"
- new "<ignore>" and "any" options for "homehost"
- numerous bug fixes and minor enhancements.
