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?
