Under title expanding existing partitions, consider adding something like the following:

The below assumes a single partition per disk. If you have multiple partitions in different raid arrays (eg sdd1 in md0, sdd2 in md1 etc) then ensure you fail/remove and re-add all relevant partitions.

This is just so people don't forget to check whether they have multiple partitions on the disk they are about to remove!

Expanding the size of an array while a write-intent bitmap is active can easily be fatal to the array. Trust me, I have the sleepless night to prove it. Neither mdadm nor the kernel code presently tests for this set of conditions when you attempt the --size=max; adding such a check and returning an error would be nice.

It is also helpful to explicitly show the wait for array recovery to complete before creating a write-intent bitmap, in case someone cuts-and-pastes the examples into a script.

It might be nice to use /dev/mdX consistently in the examples, instead of the occasional /dev/md0 and /dev/md1.
