Subject: ANNOUNCE: mdadm 3.3.4 - A tool for managing md Soft RAID under Linux
|
||||||
|
|
||||||
|
I am somewhat disappointed to have to announce the availability of
|
||||||
|
mdadm version 3.3.4
|
||||||
|
|
||||||
|
It is available at the usual places:
|
||||||
|
http://www.kernel.org/pub/linux/utils/raid/mdadm/
|
||||||
|
and via git at
|
||||||
|
git://github.com/neilbrown/mdadm
|
||||||
|
git://neil.brown.name/mdadm
|
||||||
|
http://git.neil.brown.name/git/mdadm.git
|
||||||
|
|
||||||
|
In mdadm-3.3 a change was made to how IMSM (Intel Matrix Storage
|
||||||
|
Manager) metadata was handled. Previously an IMSM array would only
|
||||||
|
be assembled if it was attached to an IMSM controller.
|
||||||
|
|
||||||
|
In 3.3 this was relaxed as there are circumstances where the
|
||||||
|
controller is not properly detected. Unfortunately this has negative
|
||||||
|
consequences which have only just come to light.
|
||||||
|
|
||||||
|
If you have an IMSM RAID1 configured and then disable RAID in the
|
||||||
|
BIOS, the metadata will remain on the devices. If you then install
|
||||||
|
some other OS on one device and then install Linux on the other, Linux
|
||||||
|
might eventually start noticing the IMSM metadata (depending a bit on whether
|
||||||
|
mdadm is included in the initramfs) and might start up the RAID1. This could
|
||||||
|
copy one device over the other, thus trashing one of the installations.
|
||||||
|
|
||||||
|
Not good.
|
||||||
|
|
||||||
|
So with this release IMSM arrays will only be assembled if attached to
|
||||||
|
an IMSM controller, or if "--force" is given to --assemble, or if the
|
||||||
|
environment variable IMSM_NO_PLATFORM is set (used primarily for
|
||||||
|
testing).
|
||||||
|
|
||||||
|
I strongly recommend upgrading to 3.3.4 if you are using 3.3 or later.
