Almost all Linux MD articles and references say to set the partition type to Linux RAID autodetect, yet you and a few others refer to this process as deprecated, without explanation or alternative.  People finding this article don't need mysticism -- we need solutions, which are proving hard to come by in an arena that is still anachronistic and immature. Management of disk volumes should be an intrinsic service of the OS, with straightforward management tools.  Coming from a Solaris environment where ZFS is a dream to use, I'm nothing short of floored at how primitive this stuff appears to be on all Linux distributions.

There is information about autodetect in [[RAID_Boot]] - link added to the page. There is plenty of information about LVM on the internet. I look forward to seeing your contributions to improving this situation.

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.
