BRAVO!!!!!!
Thanks a million Chris! After following your advice on recovering the
MBR and the GPT the arrays re-assembled automatically and all data is
there.
I already changed the type to make it consistent (FD00 on both
partitions) and working on setting up the timeouts to 180 at boot
time. Other than replacing the green drives with something more
suitable (any suggestions are welcome), what else would you suggest to
change to make the setup a bit more consistent and upgrade proof (i.e.
having different metadata versions doesn't look right to me)?
I'd also like to thank Wol and Adam for their help and for keeping the
thread alive.
Thanks again and again,
This is the current status:
