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 "" and "any" options for "homehost" - numerous bug fixes and minor enhancements.
