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"
