Sorry, don't know what you are talking about. I'm not really interested in receiving donations.

I'm not really sure what you are asking beyond "It doesn't work, please help"... You mentioned RAID5 and there only seems be be one RAID5 in the mdadm --examine output, on /dev/sd[aceh]3 It is an 8-disk RAID5, so 4 devices seem to be missing? The "Update Time" is 21st April. So this array has not been used for over 5 months??? I think you need to spell out in more detail what the problem is, what the current state is, how it got that way, and what you hope to achieve. Because at the moment I am lost.
