comment mdadm Build legacy array with 512-byte chunk
Thanks for this. I eventually broke down and used a handmade python script to access the data and copied it to another RAID with a sane block size, but if I have this issue in the future I'll be sure to take a look at it.

comment RAID-5: Two disks failed simultaneously?
For point 2. Data Recovery. Recovering Data from a RAID5 professionally can run you $20k easy. Moreover, OP let the rebuild run overnight, stressing the disk, which can cause recovery to be more difficult or even impossible. Just letting you know ahead of time. Be sure to send all disks.

comment mdadm Build legacy array with 512-byte chunk
Thank you so much for taking the time to sleuth this out. I checked the kernel source in the md driver and it would indeed be possible, because everything is referenced by number of sectors as far as I can tell. Thank you very much, I'll play with it and see what I come up with. If you copy this response as an answer I'll gladly accept.
