       Possibly you needed to specify the --backup-file

Thanks for helping me out of this...

Have you got the latest mdadm? See the "stuck reshape operation" thread
for details.

You could also try adding the --invalid-backup option to mdadm. It
shouldn't need a backup if you're adding more disk, though, so that
looks slightly odd to me.

Beyond those tips I'll not stray - my raid-fu is not the best and while
I'm confident of this information I don't believe in encouraging others
to take risks. If those don't work I'll let a better expert than me
chime in.

Cheers,
