dmraid discovers, activates, deactivates and displays properties of software RAID sets (eg, ATARAID) and contained DOS partitions. dmraid uses the Linux device-mapper to create devices with respective mappings for the ATARAID sets discovered. The following formats are supported: Highpoint HPT37X/HPT45X Intel Software RAID LSI Logic MegaRAID NVidia NForce RAID (nvraid) Promise FastTrack Silicon Image(tm) Medley(tm) VIA Software RAID Please read the documentation in /usr/share/doc/dmraid BEFORE attempting any use of this software.

    2014-02-18 - Dimitri John Ledkov <> dmraid (1.0.0.rc16-4.2ubuntu3) trusty; urgency=medium * Correct dmraid fallback imsm assembly logic. * Correct dmraid fallback ddf assembly warning message.

    2014-02-18 - Dimitri John Ledkov <> dmraid (1.0.0.rc16-4.2ubuntu2) trusty; urgency=low [ Dimitri John Ledkov ] * Do not assemble Intel Rapid (Matrix) Storage, if mdmon (mdadm) is present and not disabled. * Add breaks on mdadm, of versions which do not assembly fakeraid arrays by default using mdmon. * Drop force loading dm-raid45 module in the initramfs hook. [ Stefan Bader ] * Convert library to use the dm-raid upstream module instead of the out-of-tree dm-raid45 one. * Hack to ignore devices with less than 8 sectors (which avoids error messages when probing for meta-data). * Remove modprobe dm-raid45 from dmraid-activate. * Setting configure executable in debian/rules to avoid odd FTBS in some cases.

    2013-01-11 - Dmitrijs Ledkovs <> dmraid (1.0.0.rc16-4.2ubuntu1) raring; urgency=low * Merge from debian. To pick up NMU. Everything else is still the same: - Depend on kpartx-boot to pull kpartx into the initramfs (LP: #941874) - Depend on kpart-udeb - Breaks libparted0debian1 (<< 2.3-5ubuntu4) - Use kpartx to activate partitions - Add 25_change-uuid.patch - Add 23_pdc_dump_extended_metadata.patch - Add 21_fix_testing.patch - Add 24_drop_p_for_partition_conditional.patch - Fix once again the jmicron naming bug, upstream fix does not work - debian/dmraid-activate: Remove the special-casing of the root device which breaks in many situations and leaves the raw devices exposed. - debian/dmraid.postinst: Comment out "udevadm trigger" call in postinst for now as it has severeconsequences when mountall is installed (clears /tmp). - debian/dmraid.udev: Removed |change udev rule for dmraid-activate to prevent infinite udev event loop.

    2012-09-10 - Ulrich Dangel <> dmraid (1.0.0.rc16-4.2) unstable; urgency=low * Non-maintainer upload. * Call udevadm settle before activating dmraid devices (Closes: #677450)

    2012-10-01 - Colin Watson <> dmraid (1.0.0.rc16-4.1ubuntu9) quantal; urgency=low * Rebuild for new armel compiler default of ARMv5t.

    2012-03-20 - Phillip Susi <> dmraid (1.0.0.rc16-4.1ubuntu8) precise; urgency=low * Depend on kpartx-boot to pull kpartx into the initramfs (LP: #941874)

    2012-03-13 - Phillip Susi <> dmraid (1.0.0.rc16-4.1ubuntu7) precise; urgency=low * Fix Update initramfs hook to copy correct udev rules file with new priority of 97 instead of 85 (LP: #941874)

    2012-01-28 - Colin Watson <> dmraid (1.0.0.rc16-4.1ubuntu6) precise; urgency=low * Depend on kpartx-udeb rather than multipath-udeb, now that it exists (LP: #922646).

    2012-01-08 - Phillip Susi <> dmraid (1.0.0.rc16-4.1ubuntu5) precise; urgency=low * Switch to using kpartx to activate partitions. This allows dmraid to work on gpt formatted disks. Change priority of udev rule so it runs after kpartx. * Add 25_change-uuid.patch: Change the UUID set on partitions and internal subset devices ( each half of a raid10 ) to differentiate them from the main disk so that parted will not show the internal subset devices and kpartx will not probe them for partitions.

    2011-04-28 - Phillip Susi <> dmraid (1.0.0.rc16-4.1ubuntu4) oneiric; urgency=low * Drop 22_add_pdc_64bit_addressing.patch: breaks some pdc raid sets (LP: #770600)
