Hi

I have a challenge!!
I've been upgrading my array with larger disks, then needed to remove one of
the disk from the array (long story) so I shrunk the array and was in the
process of reducing the number of disks when I lost power and have now lost
the ability to mount the array.
So I'm now in a state where I don't know if 9 or 10 disks are in the array,
all I know is it will not start.  Because I've been swapping disks out I
don't know what order the disks are supposed to be in to re-start the array.

Running Mdadm 3.2.5 on debian kernel 3.2.0-4-amd64

I can 'start' the array with 9/10 disks (using devices a-j alphabetically)
but it is not mountable, the filesystem type is 'jbd' when it should be ext4

What can I do to get this working/what info can I provide so you can help?

Cheers
Andy
