******************************************************************************** * * * dmraid (Device-Mapper Software RAID support tool) 1.0.0.rc16 2006.09.16 * * * * (C)opyright 2004-2009 Heinz Mauelshagen, Red Hat GmbH. * * All rights reserved. * * * ******************************************************************************** Feature set: ------------ This software supports RAID device discovery, RAID set activation, creation, removal, rebuild and display of properties for ATARAID/DDF1 metadata. dmraid uses libdevmapper and the device-mapper kernel runtime to create devices with respective mappings for the ATARAID sets discovered. The following ATARAID types are supported: Adaptec HostRAID ASR Highpoint HPT37X Highpoint HPT45X Intel Software RAID JMicron JMB36x LSI Logic MegaRAID NVidia NForce Promise FastTrack Silicon Image Medley SNIA DDF1 VIA Software RAID Beside hints, enhancement proposals and patches, I want to know, if the mappings the tool creates ("dmraid -tay") are correct for your ATARAID configuration. Thank you for your support of dmraid. License/Disclaimer: ------------------- This software is released under the GPL/LGPL respectively. See file headers, LICENSE, LICENSE_GPL and LICENSE_LGPL for details. This is Alpha software and it can destroy your data! So please take backups and start accessing your data in dmraid activated ATARAID sets READ-ONLY first before you try to write it! Minimum prerequisites to run this software: ------------------------------------------- o a recent mainline Linux 2.6 kernel (includes needed device-mapper mirror changes) Additional minimum prerequisites to build this software: -------------------------------------------------------- o device mapper userpace installed (http://sources.redhat.com/dm/) o the i386 rpm or source tarball for dmraid from http://people.redhat.com/heinzm/sw/dmraid/ Build/Install: -------------- To install the rpm rpm -i [--nodeps] dmraid-1.0.0.rc16.x86_64.rpm - or - to build in an empty directory and install from source tar jxvf dmraid-1.0.0.rc16.tar.bz2 ./configure # see ./configure --help for options make make install In case you want to dietize dmraid, you need to build device-mapper with 'make CC="diet cc"' *and* install libdevmapper.a as /lib/libdevmapper_dietc.a. Run "./configure --enable-dietlibc" before make. Howto start: ------------ See "dmraid -h" for the synopsis and "man dmraid" for more details including some usage examples. Your first command is probably "dmraid -s". See TODO for known outstanding issues. See doc/dmraid_design.txt for design notes. See lib/format/template/ if you want to start your own metadata format handler implementation :) Contacts: --------- The author can be reached at <Mauelshagen@RedHat.com>.
