Thanks again Phil!
I'm almost there...

When I try to do that, I get the following message:
root@bazsalikom:~# mdadm --create --assume-clean --verbose
--metadata=1.0 --raid-devices=7 --size=1465135936 --chunk=64 --level=6

mdadm: /dev/sde2 appears to be part of a raid array:

To be able to re-assemble the array, I *have* to specify metadata
version 0.9:
root@bazsalikom:~# mdadm --create --assume-clean --verbose
--metadata=0.9 --raid-devices=7 --size=1465135936 --chunk=64 --level=6

mdadm: largest drive (/dev/sdg1) exceeds size (1465135936K) by more
than 1%
Continue creating array? y
mdadm: array /dev/md1 started.
Is this a problem? Can I upgrade my array to 1.0 metadata? Should I?
