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. >=20 > If you want me to run other diagnostics, please let me know. >=20 > You deserve a huge bonus on top of the exorbitant (of zero dollars an= d zero cents) fee I am paying you! -) :-) Thanks, NeilBrown >=20 >=20 > Thanks, > Gavin > -- > All Adults share the Responsibility > to help Raise Today's Children, > for they are Tomorrow's Society! >=20 >=20 > --- On Mon, 14/2/11, NeilBrown wrote: >=20 > > From: NeilBrown > > Subject: Re: mdadm: recovering from an aborted reshape op - to ensu= re at least one email gets through! > > To: "Gavin Flower" > > 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 > > wrote: > >=20 > > > Hi Neil, > > >=20 > > > I'll send this now. > > >=20 > > > My previous 2 attempts failed. > > >=20 > > > I had the first bounce due to HTML, but no errors > > reported for my second attempt. > > >=20 > > > I replied to you blog post. > > >=20 > >=20 > > 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. > >=20 > > 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.=A0 Then after a reboot the > > array isn't working=20 > > properly. > >=20 > > When I asked for "mdadm -Evs" I should have asked for an > > extra 'v' - I keep > > forgetting that. > > However for now:=A0 what would help is: > >=20 > > mdadm -S /dev/md1 > > mdadm -E /dev/md[abcde]2 > > mdadm -Av /dev/md1 /dev/sd[abcde]2 > > dmesg | tail -50 > >=20 > > capture all of the output and post that. > >=20 > > Thanks, > > NeilBrown > >=20 > >=20 >=20 >=20 > =20 -- To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
