Re: mdadm: /dev/md0 has been started with 1 drive (out of 2).

I checked out mdadm man page, read some pages on the web, and well, what bitmap chunk size should I go for considering these are WD Elements 2TB drives (what kind of technical information about these drives are relevant when considering a bitmap chunk size?)

Personally, I would also do:
mdadm --grow /dev/md0 --bitmap=internal
This means next time you have a similar issue, when you add the older
drive, it will only sync the small parts of the drive that are out of
date, instead of the entire drive.
