[ARMedslack] Problem with Linux 2.6.36.3 packages

2011-01-20 Thread Stuart Winter

Hi

Linux 2.6.36.3 works fine on my OpenRD client but on the SheevaPlug with a
USB hard drive (/sev/sda), the MD raid module is binding to /dev/sda and
preventing it from being used directly.

I'm not sure why this is yet - I'm looking into it.

It's actually mdadm being naughty.
I've reverted it to the previous version and I'll upload the rebuilt
installer within the next day or so.

I'm surprised nobody's noticed this problem before though.

After dd /dev/zero the whole disc, repartitioning and re-creating the
filesystems, putting mdadm-2.6 back into the installer and installing;
I now find that mdadm-3 works just fine with Linux 2.6.36.3 on the same
system.

I've no idea whatsoever what's gone on there, but it seems everything
works now.

I know - but mdadm was still taking /dev/sda even *without* partitions.
I'm guessing somehow, somewhere, there was some residue from when the disc
may have been in a raid configuration somewhere on another system from
where the disc originated (I have a collection of old discs from a
variety of places where I used to be a sysadmin).

*shrug*

You should write to the mdadm writers as that is really weird .  I would hav 
zeroed and started from there.  There are asking for failure!

That was the plan - reinstall and get a working system by putting
mdadm-2.6 into the installer, boot into the new OS and start working out
why 3.x was behaving as it was; but after the fresh installation onto
the new partitions, the problem's gone away -- so I can't replicate
anymore.

I've just reinstalled whilst having 3.x in the installer again, and the
problem no longer exists.
