[Bug 599255] Re: dmraid fails to read promise RAID sector count larger than 32-bits

[Danny Wood]

Hi Vertago1,

Yes the patch appeared to work, we merged it to the Ubuntu dev packages and it worked for some people.
The sector size was still an issue in some setups as windows appeared to use both 512 and 1024 byte sectors sizes.

However once we hit the release we quite a few people then reporting non
functioning RAID setups as the additional bytes I chose were obviously
used for something else.

Upstream dmraid doesn't accept patches. It seems that most people who
start off booting using dmraid eventually migrate to a fully Linux Mdadm
setup. Add in to that Mdadm being more feature complete and also
supporting intel matrix raid metadata and dmraid is not really required
any more except for a few odd chipsets.
