md code missing event interface
Last modified: 2014-03-16 22:42:54 EDT
It prints out:
Kernel md module does not support events.
and immediately exits.
Needs the updated kernel md code. I was told by Neil Brown that he
was going to push that into 2.6 himself. Will have to check with him.
Regardless though, it's a kernel issue, not an mdmpd issue.

Did this get pushed in? If not, we should disable mdmpd.
I still see "mdmpd failed" at startup on x86_64 with no software raid
(was everything install). No other messages. This may be a different

I've contacted the md maintainer to get a 2.6 version of the event
interface patch. No word back yet. I'll rebuild a new package today
that doesn't turn the program on by default.
The upstream md maintainer is going to try and push the event
interface into the mainstream kernel in about a week.

MD Event interface patch
This is the patch that implements the md event interface. It's currently the
only outstanding md patch that the upstream maintainer has not yet submitted to
the 2.6 kernel.
Problem still present with current kernel-2.6.6-1.435.2.3
Any plans when the patch will be integrated?
Problem still present with current kernel-2.6.7-1.494.2.2
Problem still present with current kernel-126.96.36.199-521 (Fedora Core 2)
The mdadm tools package was modified to work without the md event
interface. If it is accepted upstream (which I believe it has been as
of 2.6.10-rc1) then we will eventually get it in the future. Since
it's an optimization and not a hard requirement for operability (due
to the mdadm package update, prior to that it was a hard requirement),
I'm closing this bug out as UPSTREAM.
