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 -- cgit v1.2.3
