Description Bill Nottingham 2004-03-04 17:44:01 UTC
It prints out:

Kernel md module does not support events.

and immediately exits.

Comment 1 Doug Ledford 2004-03-30 21:08:28 UTC
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.

Comment 5 Jeremy Katz 2004-05-07 03:45:31 UTC
Did this get pushed in?  If not, we should disable mdmpd.

Comment 6 Gene Czarcinski 2004-05-07 08:22:21 UTC
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

Comment 8 Doug Ledford 2004-05-07 11:44:16 UTC
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.

Comment 9 Doug Ledford 2004-05-14 15:42:09 UTC
The upstream md maintainer is going to try and push the event
interface into the mainstream kernel in about a week.

Comment 10 Doug Ledford 2004-06-07 19:29:35 UTC
Created attachment 100940 [details]
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.

Comment 11 Boris Folgmann 2004-07-08 09:34:20 UTC
Problem still present with current kernel-2.6.6-1.435.2.3
Any plans when the patch will be integrated?

Comment 12 Dona Gibbons 2004-08-04 13:50:46 UTC
Problem still present with current kernel-2.6.7-1.494.2.2

Comment 13 Efraim MARQUEZ-ARREAZA 2004-08-31 15:24:07 UTC
Problem still  present with current kernel- (Fedora Core 2)

Comment 14 Doug Ledford 2004-11-12 17:21:56 UTC
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.
