Thanks Wols,
The version on Linux Mint I've been running is quite old. Once the
server was last configured it did not have updates. It was put on a
shelf and (mostly) left alone to serve files reliably for years.
That's good.
$ mdadm --version
mdadm - v3.2.5 - 18th May 2012
And that's not so good. If your root is not on the raid and the system
actually runs, download and run the latest mdadm. That on an old kernel
shouldn't be a problem. A franken-kernel that's been patched to buggery
probably is.

Do you want the good news or the bad news? The good news is we can
probably recover your data. The bad news is you're probably looking at
replacing all your drives :-(
https://raid.wiki.kernel.org/index.php/Timeout_Mismatch
A cursory glance says you have several drives that fall foul of this.
Again, if your system is bootable, you NEED to configure Brad's script
to run. I'll go into it a bit deeper as I dig through your reply.

Greens aren't suitable - and this is sdc, the dodgy drive, so I suspect
using it in a raid array has knackered it.

Okay, we'll assume sdc is dead. The first thing is to try to assemble
the remaining disks without it. Boot from a rescue disk so you've got
the latest and greatest available. And don't forget, if you get "device
busy", you've probably got the remains of a previous assemble messing
things up, so you need to do a --stop. Just DON'T do a --force, not yet.
Next thing we need is the event count - I think that's mdadm --examine
over each partition that makes the array.
And make sure you've got a replacement for that Green. You NEED to get
rid of it.
Let's see how it goes ... if the array assembles fine with the rescue
disk, just add your new disk and replace sdc, but make sure Brad's
script has enabled ERC!
Cheers,
Wol
