Yes - vger.kernel.org doesn't like html.
Normal attachments should work - and you should get a bounce-message
if there is something odd.
But this and the following messages did get through.

For those on linux-raid: the background is that a reshape for a RAID6
to change chunksize was interrupted by the admin killing the mdadm
which monitors the reshape.  Then after a reboot the array isn't working 
properly.

When I asked for "mdadm -Evs" I should have asked for an extra 'v' - I keep
forgetting that.
However for now:  what would help is:

 mdadm -S /dev/md1
 mdadm -E /dev/md[abcde]2
 mdadm -Av /dev/md1 /dev/sd[abcde]2
 dmesg | tail -50

capture all of the output and post that.

Thanks,
