Greetings,
A customer is running RedHat 5.3 and has inquired regarding the latest version of mdadm for that version of RedHat.
I am having some difficulty responding to the customer with the degree of confidence required for this production environment.
Is mdadm version 3.2.2 compatible with RedHat version 5.3?
Thank you in advance for considering this inquiry

In theory all later versions of mdadm are compatible with all kernels. Later versions add features, remove bugs, and sometimes add bugs.
The real question is probably "Has it been tested" or "is someone willing to
provide support". Maybe you should ask Redhat??

It's a little bit more complex than that. The mdadm package in rhel is responsible for boot up bring up of md raid arrays, and between rhel5 and rhel6 we changed boot loaders, changed init scripts, changed over to doing udev incremental assembly, and a host of other things. I have resisted the urge to put mdadm 3.x on rhel5 because it behaves differently and the particular quirks of mdadm 2.6 might or might not be relied upon by those boot scripts. So, my latest build for rhel5 is mdadm-2.6.9-3. Now, whether or not even just that much of an update would work with something as old as rhel5.3 with its (I'm sure) not updated mkinitrd or initscripts is another question.
