Hi Phillip,
Mdadm does not care about the controller unless you created IMSM
based RAID. Basically you can create that type of RAID *only* on
Intel based platforms with OROM enabled. It's Intel solution, we
support it and we maintain it. It's very specific type of metadata.
[...]
Warnings about potentially troublesome situations are good, but
outright refusal is not. Yes, I realize it would be a problem for
Windows due to the poor way the driver has to be implemented ( why
can't the OROM see other disks on other controllers? ), but sometimes
you don't care about that. For instance, if you are setting up the
array on one machine where you can not connect all of the drives to
the same controller ( and do not care about booting from the array on
this machine ), but you are planning on moving them to a machine where
they will be. This is just one example of many situations where you
need to be able to say "I know what I'm doing, go ahead anyway".
Isn't there, or wasn't there, an environment variable for mdadm called
something like IMSM_PLATFORM_IGNORE for precisely this scenario? Is that
what this patch series disabled?
Cheers,
John.
