If I hear about them they will be fixed in 3.3.1. +git log reports nearly 500 changes since 3.2.6 so I won't list them +all. + +Some highlights are: + +- Some array reshapes can proceed without needing backup file. + This is done by changing the 'data_offset' so we never need to write + any data back over where it was before. If there is no "head space" + or "tail space" to allow data_offset to change, the old mechanism + with a backup file can still be used. +- RAID10 arrays can be reshaped to change the number of devices, + change the chunk size, or change the layout between 'near' + and 'offset'. + This will always change data_offset, and will fail if there is no + room for data_offset to be moved. +- "--assemble --update=metadata" can convert a 0.90 array to a 1.0 array. +- bad-block-logs are supported (but not heavily tested yet) +- "--assemble --update=revert-reshape" can be used to undo a reshape + that has just been started but isn't really wanted. This is very + new and while it passes basic tests it cannot be guaranteed. +- improved locking between --incremental and --assemble +- uses systemd to run "mdmon" if systemd is configured to do that. +- kernel names of md devices can be non-numeric. e.g. "md_home" rather than + "md0". This will probably confuse lots of other tools, so you need to + echo CREATE names=yes >> /etc/mdadm.conf + or the feature will not be used. (you also need a reasonably new kernel). +- "--stop" can be given a kernel name instead of a device name. i.e + mdadm --stop md4 + will work even if /dev/md4 doesn't exist. +- "--detail --export" has some information about the devices in the array +- --dump and --restore can be used to backup and restore the metadata on an + array. +- Hot-replace is supported with + mdadm /dev/mdX --replace /dev/foo + and + mdadm /dev/mdX --replace /dev/foo --with /dev/bar +- Config file can be a directory in which case all "*.conf" files are + read in lexical order. + Default is to read /etc/mdadm.conf and then /etc/mdadm.conf.d + Thus + echo CREATE name=yes > /etc/mdadm.conf.d/names.conf + will also enable the use of named md devices. + +- Lots of improvements to DDF support including adding support for + RAID10 (thanks Martin Wilck). + +and lots of bugfixes and other little changes. + +NeilBrown 3rd September 2013 diff --git a/ANNOUNCE-3.3.1 b/ANNOUNCE-3.3.1 new file mode 100644 index 0000000..7d5e666 --- /dev/null +++ b/ANNOUNCE-3.3.1 @@ -0,0 +1,23 @@ +Subject: ANNOUNCE: mdadm 3.3.1 - A tool for managing md Soft RAID under Linux + +I am pleased to announce the availability of + mdadm version 3.3.1 + +It is available at the usual places: + http://www.kernel.org/pub/linux/utils/raid/mdadm/ +and via git at + git://github.com/neilbrown/mdadm + git://neil.brown.name/mdadm + http://git.neil.brown.name/git/mdadm.git + +The main changes are: + - lots of work on "DDF" support.

Unfortunately this has negative +consequences which have only just come to light. + +If you have an IMSM RAID1 configured and then disable RAID in the +BIOS, the metadata will remain on the devices. If you then install +some other OS on one device and then install Linux on the other, Linux +might eventually start noticing the IMSM metadata (depending a bit on whether +mdadm is included in the initramfs) and might start up the RAID1. This could +copy one device over the other, thus trashing one of the installations. + +Not good. + +So with this release IMSM arrays will only be assembled if attached to +an IMSM controller, or if "--force" is given to --assemble, or if the +environment variable IMSM_NO_PLATFORM is set (used primarily for +testing). + +I strongly recommend upgrading to 3.3.4 if you are using 3.3 or later. + +NeilBrown 3rd August 2015. |
