I'm no expert either, but looking at the blog, I'm worried he might have
trashed the array with almost the first thing he did :-(
"add" says it will add a drive as spare if it didn't originally belong
to the array. If it adds a spare to a degraded array, the array will
immediately start to repair itself.
OOPS!!! As it sounds like exactly this could have happened - mdadm
didn't recognise the disk as it added it.
Just speculating, but unfortunately this seems quite likely :-(
Cheers,
Wol
