Hi Neil,
I'll send this now.
My previous 2 attempts failed.
I had the first bounce due to HTML, but no errors reported for my second attempt.
I replied to you blog post.
Thanks,
Gavin

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.

I am happy to send it, if you think it will be useful. No, not necessary. I guess whatever boot script tried to assemble the device didn't know to tell it about a backup file and so the assembly didn't complete, leaving you to pick up the pieces, but with no clear message explaining what the pieces were... I hope that in a few releases we can largely do away with the backup file so I probably won't put much effort into trying to make this all run more seamlessly. > > If you want me to run other diagnostics, please let me know. > > You deserve a huge bonus on top of the exorbitant (of zero dollars and zero cents) fee I am paying you! -) :-) Thanks, NeilBrown > > > Thanks, > Gavin > -- > All Adults share the Responsibility > to help Raise Today's Children, > for they are Tomorrow's Society! > > > --- On Mon, 14/2/11, NeilBrown <neilb@suse.de> wrote: > > > From: NeilBrown <neilb@suse.de> > > Subject: Re: mdadm: recovering from an aborted reshape op - to ensure at least one email gets through! > > To: "Gavin Flower" <gavinflower@yahoo.com> > > Cc: linux-raid@vger.kernel.org > > Date: Monday, 14 February, 2011, 13:00 > > On Sun, 13 Feb 2011 15:10:36 -0800 > > (PST) Gavin Flower <gavinflower@yahoo.com> > > wrote: > > > > > Hi Neil, > > > > > > I'll send this now. > > > > > > My previous 2 attempts failed. > > > > > > I had the first bounce due to HTML, but no errors > > reported for my second attempt. > > > > > > I replied to you blog post. > > > > > > > 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.

Unfortunately, it stopped in the same place. It ran for over an hour before I went out, it had stopped by the time I got back a couple of hours late. I should have captured dmesg before I rebooted, but I didn't (I blame walking for almost an hour in the hot Sun...). I will follow this with email with hopefully useful diagnostics...
