Subject: ANNOUNCE: mdadm 2.0-devel-1 DEVELOPMENT RELEASE - A tool for managing Soft RAID under Linux I am pleased to announce the availability of mdadm version 2.0-devel-1 It is available at http://www.cse.unsw.edu.au/~neilb/source/mdadm/ and http://www.{countrycode}.kernel.org/pub/linux/utils/raid/mdadm/ as a source tar-ball and (at the first site) as an SRPM, and as an RPM for i386. mdadm is a tool for creating, managing and monitoring device arrays using the "md" driver in Linux, also known as Software RAID arrays. Release 2.0-devel-1 is a development release that quit possible has bugs. It released in the hope of getting wider testing. It adds support for version-1 superblock which allow more that 28 devices in an array (among other things) and for bitmap-based-write-intent-logging which can improve resync speed after an unclean shutdown. The bitmap logging requires patches which should be in the next -mm release after 2.6.11-rc4 and can be downloaded from http://neilb.web.cse.unsw.edu.au/patches/linux-devel/2.6/2005-02-18-00/ which contains patches against 2.6.11-rc3-mm2. Development of mdadm is sponsored by CSE@UNSW: The School of Computer Science and Engineering at The University of New South Wales NeilBrown 18 February 2005
