Subject: ANNOUNCE: mdadm 2.3 - A tool for managing Soft RAID under Linux I am pleased to announce the availability of mdadm version 2.3 It is available at the usual places: http://www.cse.unsw.edu.au/~neilb/source/mdadm/ and http://www.{countrycode}.kernel.org/pub/linux/utils/raid/mdadm/ mdadm is a tool for creating, managing and monitoring device arrays using the "md" driver in Linux, also known as Software RAID arrays. Release 2.3 fixes an assortment of bugs including the "--assemble --scan" crash. It also makes mdadm better at handling very large arrays. Finally, it adds some functionality to support some pending kernel features such as raid5 reshaping. Changelog Entries: - Try /etc/mdadm/mdadm.conf if /etc/mdadm.conf doesn't exist. This provided compatability for Debian. - Fixed for version-1 superblock: report chunksize for raid6 and raid10 make sure device size used is a multiple of chunksize - Fix "--assemble --scan" crash. - Fix completely failure to create array on ppc64 - Fix memcmp in place of memcpy - A few minor improvements to online help - Clean up usage of 'long long' for used-size of devices, so that it is possible to create a raid1 of 7TB devices! - Make internal bitmaps work on 7TB raid1 arrays. - Provide error message if --examine doesn't find any superblock. - Report 'reshape' status in --examine - this depends on kernel patches that are not yet finalised. - Report bitmap status in --detail and --examine - Default to v1 superblocks instead of v0.90 if the array is too big for 0.90 to handle. - Sort the output of "mdadm --detail --scan" so that it is in a suitable order for assembling arrays. i.e. components come before an array that they are part of. - Print size of large reiserfs array properly went warning of possible confilcts. Development of mdadm is sponsored by SUSE Labs, Novell Inc. NeilBrown 2nd February 2006
