The mdadm utility can be used to create, manage, and monitor MD
(multi-disk) arrays for software RAID or multipath I/O.
This package automatically configures mdadm to assemble arrays during the
system startup process. If not needed, this functionality can be disabled.

mdadm (4.1~rc1-4) unstable; urgency=medium
* Cherrypick master patches up to 20th of July 2018. LP: #1781427
* Make safe-timouts udev rules compatible with usr-split systems.

mdadm (4.1~rc1-2) unstable; urgency=medium
* Install identical udev rules into d-i installer udeb, as used in the
installed system. Specifically, post-processed rules with full path to
mdadm binary subsituted, instead of installing useless rules with the
template variable BINDIR. LP: #1705215

mdadm (4.1~rc1-1) unstable; urgency=medium
* New upstream release.
* Import patches since rc1.
* Bump standards version & debhelper compat.
2017-10-10 - Dimitri John Ledkov <>
mdadm (4.0-2) unstable; urgency=medium
* Ship mdadm-shutdown.service and suggest dracut-core. Users of systemd
with rootfs on Intel Matrix Raid and DDF external metadata-raid arrays
that require mdmon monitoring, may wish to install dracut-core package
and enable mdadm-shutdown.service. This will create a shutdown
initramfs, that systemd-shutdown can pivot to. This may result in an
improved shutdown behaviour with less hangs and synced raid
arrays. The generated initramfs will takeover mdmon monitoring, wait
for the arrays to be clean before stopping them and unmounting
everything and finally executing requested shutdown command.
* Bump standards version, no changes required.
* Bump debhelper to 9.
* Add second email address to avoid NMU warnings.
2017-06-22 - Dimitri John Ledkov <>
mdadm (4.0-1) unstable; urgency=medium
* New upstream release. LP: #1668128
* Drop warnings that raid arrays are missing from the initramfs
configuration. Instead have a positive message as to which arrays are
included in the initramfs.
* Add a warning to mkconf generated file that mdadm.conf is copied into
* Fix checkarray script bugs. LP: #1599428 Closes: #787950 Closes: #843665

mdadm (3.4-4) unstable; urgency=high
* Bring in changes from Ubuntu, to make the two packages in sync:
- Drop README.Debian, quite out-of-date w.r.t. current packaging.
- debian/control - on ubuntu, downgrade default-mta from Recommends to
- update-grub in postinst, if available (note does not update grub1).
- drop stderr warnings in postrm.
- drop presubj, out of date, and all types of bugs are welcomed.
- on ubuntu, install apport package hook.
- on ubuntu, install incremental assembly udev rules into udeb.

mdadm (3.4-3) unstable; urgency=high
* Fix UUID= grep for configured RAIDs to be case incesetive, regression from 3.4-2.
* Re-trigger block devices at the start of local-block mdadm loop, to
re-incrementally assemble disks that appeared before RAID
personalities were registered with the kernel.
* Also, invoke non-incremental assembly of raid arrays in the
local-block loop to support running mdadm with user-exported variables
specified via param.conf.
* Set Vcs- fields to dgit repositories.
* Closes: #830770, #830300.
